I just upgraded to 8.1. When my computer boots there are two users. If I click the one with full administration privilages, I get the blank screen that everyone is talking about. If I ctl-alt-del and select "switch user " I can get the Guest user and the screen is fine. Start, swipe, desktop all work.

I have explored all the threads I can find here and none seem to help my situation. For example, i don't think it can be bad drivers if one user works fine.
Any Help?

Is one reason I said 'do the basics'.



Malware is NOT a virus. Malware is a way to get YOU the user to do things your not supposed through the use of clever Social Engineering things that you just 'CLICK' without thinking. The most common example was the 'Windows 201_ (fill in the year) Antivirus ALERT!' that would pop up. By installing 'something' else (usually people...
I'm not sure if the guest account prohibits elevated command prompts, but try it.

If you can't do it from the guest account, you'll have to do it from Safe Mode.
http://www.howtogeek.com/107511/how-to-boot-into-safe-mode-on-windows-8-the-easy-way/?PageSpeed=noscript

Once you've got the admin command prompt, create a new admin user account:
net user /add [username] [password]
net localgroup administrators [username] /add

See if Win 8.1 will let you login to this new admin user account.
 
Can be anything from the NON Guest is loading a program as part of its profile that is taking a long time under Windows 8 (aka not compatible) to you have Malware hosing up just that account.

At this point I would do a CLEAN reinstall of the OS, recreate accounts etc. When you 'upgrade' like this, it normally has issues and there is no 'single fix' as you can't "see" what is causing the problem most of the time.
 
Well, one new piece of information. I just left it sit blank while I did other things. I believe it "went to sleep". When I brought it back the "wakeup" screen appeared. I swiped from the bottom and both users are working fine. No blank screen.
Powered down. Powered up. Got the wakeup screen. Swiped, login to Guest works, login to the admin user is a blank screen.

I think I have it set to go to sleep after 10 minutes. I'll wait and see what happens then.

I don't want to go through all the potential problems of creating new admin account or another intall of the OS. I have done three OS installs in the last two days and always come to this.
 
I believe I just confirmed that if I let the 'puter go to sleep it will "wake up" and all users have a screen.
If I hibernate and restart it also works for both users.

So why does it hang up after a shutdown and how can I get it beyond that?
 
As I said it sounds like a bad load. It may not have the proper updated files necessary to ensure it is loading right, but does so once it does a full 'save' to the hibernation file then reloads it. Normally the symptoms are indicative of a corrupt profile, which requires a new one. Have you tried creating a test new admin account then see if it too suffers the same face. I am of the belief with the upgrade it may have things not normal for the system as it is now that worked before, which always comes back to a reload of OS.

BTW there is more then 8.1 upgrade you still need to apply the 8.1 UPDATE to get updated files from Microsoft.
 
I kept thinking that when I wanted to go to the admin account it was almost getting past the black screen. I just needed to find the last thing that would get it past the problem. I must have tried 20 or 30 different things I found surfing. Nothing worked.
So I decided I should start another admin level user as recommended. I'll describe what I did so others can follow.
Since the only admin user had a blank screen I needed a way to start another user. I found I could do the following:
ctrl-alt-del gave me a few choices including Task Manager.
In Task manager, File, Run new task,
type control.exe in the box and check "Create this task with admin priv"
Select user accounts, change user accounts, Add a new user.
And I get a window labeled "explorer.exe" and the message "class not registered"
I found I should Run New Task with admin priv and "regsvr32 ExplorerFrame.dll" It didn't work.
I got the message "The module "ExplorerFrame.dll" was loaded but the entry-point DLLRegisterServer was not found. Make sure that "ExplorerFrame.dll" is a valid DLL or OCX file and then try again."
I tried a lot of things like a new admin task and run cmd, then sfc.exe /scannow. It found no problems. Waste of a lot of time. Just to let you all know.

Now here is where everyone hates me. While surfing to a solution to create a new user, suddenly the black screen (that was behind my Task Manager and Control Panel windows) turned into the desktop I had created for this current admin user.

So I tried the Add a new user in PC settings and instead of the Explorer Error problem, it let me start a new user. It seems that after a long time and without any definitive action on my part, the black screen fixed itself just as it had a few times before and fixed the "Explorer Class not registered" problem also.

So I started a new admin level user and it went through all its steps loading apps and whatever. When it finished I selected the new user and damit, the black screen is back for the new user. FAILURE.

Luckily I could switch users to the admin user that I used to create the new user and the screen was still usable. Before I go further I am creating a Recovery Drive assuming I can find a 8GB flash drive laying around.
To be continued.
 
Well, I found that the new administrator account isn't a full power administrator. The true administrator is hidden and must be activated. To do that I have to run cmd.exe in administrative mode. To do that, press the WIN+X keys. In the list at the lower left find "Command Prompt (Admin)" and click.
Then cmd.exe and enter the command "net user Administrator /active:yes"
I don't remember what happened next but at some point I got a page with four "people" on it.
Administrator,
Admin (the one I created thinking it could have administration privileges but not a lot.)
The original "almost" administrator account.
and
Guest.

When I started the full Administrator user I got the damn blank screen again. I went out and shoveled some snow and when I came back the desktop was there.

While contemplating my next move I got a message that I needed to restart to install updates. I clicked restart and after it restarted I attempted to start the full administrator account but, you guessed it, blank screen.

So I thought I would type this update while hoping for the blank screen to change to the desktop.
 
Okay Admin1 account 'resolving' sounds like it is hung up waiting to do things. Now I am NOT sure how long you 'waited' the first or the 20th time with a BLANK screen to just let it 'work through it'. Normally when you need to upgrade / etc. you have the issue that it needs to recreate the HIVE, reset regs etc. and if you went from 32-64 OH FORGET IT! You just shot yourself in the foot hard.

That Admin2 does the same thing as a new account proves that the base image A) files B) default user account settings is NOT working as you expect it. While technically could be one of the "apps and whatever" that is causing the issue I would still say it is UNSOLVABLE because you replaced key system files and now you have a no way to track down which file(s) are the issue or combination of files or just because of that file with this program on that network design with that rights package etc. Your now at the point where you would be paying programmers to use debugging tool for 'patch maintenance' and that is far beyond the necessary 'solution' for the users, but it is the ONLY way to resolve it on this path you taken.

MY suggestion, no INSISTENCE, is you will need to 'start from scratch'. I would do system swaps at this point. Simply take a base system that is comparable to these people, and install Windows, make all the necessary patches and fixes to it FIRST till your on Windows 8.1Update and this week's patches. THEN install your apps one at a time, updating each and see if you have a problem anyway along the way. IF you do, then you most likely figured out the most likely culprit causing the issue, if not then it proves what I am saying, the 'inplace update' you did wasn't performed properly / correctly and has corrupted key components (HIVE, etc.) that aren't just a SFC fix.

Now some caveats,
1) I would NEVER give end users ADMIN rights unless there was a absolute hard (unable to perform their entire job) limit reason why. They should ONLY be given Power user and Admin rights should be limited to a IT Support account they NEVER have the password to.
2) Since Vista the old 'way' to replicate systems has vanished away due to the new security structure (you do know that the Administrator account is NOT the God account anymore, like in old XP, but just Power User right?). As such the 'only' way to replicate that finishes image is to use the Microsoft® Deployment Toolkit 2010 with a SMS server setup on the domain, now if you wish to make a base line image then deploy it. Normally people are doing Hybrids which has the base OS then pushing via SMS patches updates and apps based on group access rights, for example someone in the Accounting Department doesn't need to have access to the Personnel Records Department's apps and vice versa, so the push would be based with different packages.
3) You need to really step back (based on your other answer to my previous response) that the end users may not WANT you to do this, the better question is, can they live with these results? Can they deal with computers functioning as your discussing now? IF NOT, then the answer is, sorry but either we do it this way or your stuck with this 'solution'.
 
Tom,
Thanks. But I am the only user. This is my tablet that I use for leisure. A little surfing, taking notes at meetings, reviewing spreadsheets and documents when I don't feel like sitting at the desktop. So I can do anything I feel might help and not worry about how many admins there are.

I took a break and decided to basically do what you advise as far as start from scratch. I found this and I think it relates to my problem:

"The black screen was because SFC /scannow had restored system files and Windows could no longer load the custom style I had installed into Windows\Resources\Themes. I had overwritten the default aero.theme with a custom one. PEBKAC."


I did change the theme for the first account I started because the default hurt my eyes. But I just selected one of the other options in Windows 8.1, nothing strange. But I did it after I started the Guest account. So the Guest account used the default theme. After I changed the theme of the first account, that caused my problem. Then every account I started after that used the theme of the first account because that was the only one with enough privileges. So right now, after activating the real Admin account I have four accounts. Three use the new theme and Guest has the default. The three all hang at the blank screen. Guest works every time.

And something that tends to confirm that is, after the "long time", when any other user passes through the blank screen, the theme it uses is the default theme not the one I had changed it to.

So "start from scratch" seems the "shortest way home" for me. I already copied the Documents files to my NAS so even if I wipe a lot I won't lose anything.

I believe the Recovery USB I made may have the same problems. The last time I checked I had a recovery partition on the SDD. So tomorrow I will try to recover to Windows 8, install 131 windows updates (This will be the second time doing this). Then download Windows 8.1 and not change a single thing until I am sure it is very stable.

I want to thank you for taking the time to read through all of my post and really understand it enough to provide what I am sure is very good advice. I'll report back the results.

Well to clarify a couple points;

1) The 'hidden' account you unlocked was just the Administrator account. The Administrator account doesn't hold any more special 'powers' than a normal Admin account (anything you remember about XP and before toss it out completely, it isn't relative anymore since Vista - I had to learn this with 7).
2) NO the Administrator account is not the 'true' Hidden 'Admin' aka GOD account. The TRUE account is called "Trusted Installer" and you can NOT active or access it. It actually has 'rights' over Admin and is integrated into Windows Executable itself as the true 'GOD' over your OS (aka Microsoft is Admin not you over your OS). If you mess with files assigned to Trusted Installer (Case in point 'default theme') without using 'Take Ownership' (google the add on reg) you are fighting Trusted Installer's code and you will lose (blank screen). You will have to learn (as I have and others) to pick your battles and you can NOT just take ownership of 'everything' or 'most things' but very limited things (Backgrounds, Themes, Fonts, etc. minor things) or else it breaks the system in a myriad of ways, all not just simple DO A get B result either.
3) As I mentioned updating to Windows 8.1 through the store isn't the only part. You then need to 'update the update' to 8.1 Update through Windows Update, to get all the past year and going forward patches. This include drivers that are corrected and otherwise. I use a simple tool, SLIMDRIVERS, to find all the latest compatible drivers no matter what Windows / other tools say. Normally some stupid little one (i.e. the I/O interface for USB that allows the touchscreen to work) can be not updated correctly and SLIMDRIVERS does a fine job of finding it too.
4) Windows 10 - aka ONE Windows to RULE THEM ALL! Has been trial released to the public and will be final release by Tax Day and is a FREE UPGRADE to all LEGAL Windows 7/8 users. I personally am doing mutliple systems here in my home when it is final release, but from what I seen of those 'testing it', looks solid already and solves the many UI issues anyone with a 'desktop' or laptop had with Windows 8.
 
Well, that was a waste. Win 8.1 overwrote the recovery so I can't go back.

Samsung is sending me a Windows 8.0 recovery CD. Snail mail. They can't send a 8.1.

So when I get it I have to run the CD.
Install a few hundred updates to 8.0
Download 8.1.
Hope it doesn't end up with the same problems.

It's enough to make a guy want to go Chrome or even iPad.
 

You can thank Microsoft for that one. In their infinite wisdom, they made Windows 8.1 keys different from Windows 8.0 keys. So if your laptop was sold with a Win 8.0 key, the manufacturer can't give you 8.1 (without paying Microsoft for another license). Their only choice is to force you to restore to 8.0, then do the free update to 8.1.
 
Well, the key is in the bios. I found a program that claims to have pulled it out. It lists the same key for 8.0 and 8.1 so I tried a direct download of both. Both rejected but not as "invalid" just something like "wrong type".

So a list of things I am looking forward to when I receive the CD.
This tablet does not have a CD reader.
The reader is on my desktop 'puter.
I won't be able to establish a network connection when I try the recovery (I can now)
I hope I can transfer the CD to a USB.
I hope Win 8.1 now installed will allow me to go back to 8.0

What else have I not thought of, Murphy?
 


You can simply get the download from Windows.com website, there is steps on there on how to download Windows to a USB and then try off that. Otherwise you would need to buy a USB DVD drive (won't be a CD) to plug into the tablet, but the tablets don't have enough 'power' to power it, so make sure you get one with external power.

NO, whenever you do a OS update you CAN NOT GO BACK. Also Microsoft / all others have already stated updating to 8.1 then 8.1 Update is REQUIRED to receive any patches, fixes, updates. Non compliance will prevent your Windows from being fixed, patched, and protected when they find problems, holes, or security concerns.

You COULD just wait till Windows 10 is released in April, the technical review version is available at present and is a FREE update to all Windows 7 and 8 users.
 
I have shut it down many many times. Windows 8.1 has been feeding me updates everyday and I install them hoping the update might fix the problem. Most of thm reqire a reboot.

Right now I have 4 users. One is just a Guest with no privilages. Two are Admin and one is the "Super Admin". Only the Guest will boot correctly. The others will hang with a blank screen. If I wait long enough, and that can be hours, the blank one I have active may follow through and give the correct screens. I am not doing anything, just letting it sit. It is like it is off searching for something for a long time then gives up and goes to cpmpletion.
 
No, shut off fast boot/hybrid shutdown. It's under power options. Windows 8 Doesn't really shutdown unless that's deactivated. It does a hybrid hibernation. A mode which has been responsible for EVERY black screen I have seen to date on windows 8.

Well, it looks like it was a virus or virus like program. I ran Malwarebytes and it found about 37 items to quarantine. When it finished everything was running fine.....Well except for getting back to the setup I had before.

So, I am pondering how could a virus get on this tablet. I haven't had a virus on any of my computers in 10 or more years. It was working fine. Every few days I would get a splash screen saying "Click here to update Windows 8.0 to Windows 8.1". Could this be a virus? I finally decided to do the upgrade and clicked on the splash screen. I thought it went through the Windows Store.

I only ran Malwarebytes because the Windows 8.0 recovery disk from Samsung has not arrived yet. And I think we all agree it won't work since 8.1 is installed. I just thought I would go through the motions for Samsung to get to the next level of support. Now I will call it a day with this problem.


Thanks for all the help and advice.

One final thing. Should I start a new thread and include the Quarantine log from Malwarebytes? Maybe smarter minds then me can analysis it and provide some knowledge for others that may hit this problem. I hate to think they would find this thread and go through all this before finding the final post.
 


Is one reason I said 'do the basics'.



Malware is NOT a virus. Malware is a way to get YOU the user to do things your not supposed through the use of clever Social Engineering things that you just 'CLICK' without thinking. The most common example was the 'Windows 201_ (fill in the year) Antivirus ALERT!' that would pop up. By installing 'something' else (usually people either installing PIRATED stuff, Toolbars, or just 'clicking through' a install without reading it) they installed this piece of Malware which would then alert you to a few steps you need follow to 'remove' a virus. When instead being 'technically naive' they instead are helping to actually infecting the system (turning off firewalls, installing a web based 'plugin' etc all under the 'admin acct').

Because Malware acts like 'normal' software it can't be "see" by antivirus programs as they are looking for malicious code 'attacking' or altering the system in specific ways. The difference to understand is a Doctor looks for symptoms for your illness to diagnose your illness btu that has NOTHING to do with stopping all the Solicitor Phone calls / SPAM emails or Adverts sent to your physical mailbox right? Well that is the same difference between what Antivirus looks for and what Malware does.

I am sorry to say though "I haven't had a virus on any of my computers in 10 or more years." I hear from people is 100% of the time false. It has always been you just didn't realize you had viruses (people 'determine' they have a virus ONLY when the antivirus says they have one, which is a false assurance) and you just 'worked around' problems you ran into, which were caused by malware and viruses. Even though I have Masters degree, Certifications, and highly educated / experienced (20 years) in many all levels except Data Centers systems support, I can say I have had viruses come along on my systems in the last 10 years or more, and I am a professional whom knows how to look out for them.

Educating yourself is the key to understanding the difference, then a false sense of relying on 'automated' systems to tell you, which they can't. The computers are ALWAYS dumb... and they just make dumb happen 1000% faster and more complex then we can normally respond. So we need to be aware what the computers are doing and know what we expect them to do and realize the difference to 'fix' the computer from doing the wrong thing it doesn't understand it is doing.



No this is NOT a virus, and NO you weren't getting updates, you can't Microsoft already said so (http://www.computerworld.com/article/2484495/microsoft-windows/microsoft-mandates-windows-8-1-upgrade.html) .
I would suggest the Idiot's Guide series (LOVE the books!) and get the Idiot's Guide to Windows 8, since Vista came out things are very different then they were 10 years (XP backwards) ago. There is ALOT of difference and depending on your knowledge you can understand how SERIOUS the differences are or not.

Either case, Microsoft was STUPID, you install Windows 8, then you have to go to Window Update to update to the point that Microsoft Store (where you get 'Windows APPS' like a cell phone) to get the Windows 8.1 update. Then your still not done, then you need to go back to Windows Update and update the update so you now at Windows 8.1 Update edition, then you need to add on ALL the fixes / patches / updates since then as well. That is how you get a 'currently supported' Windows, and is what I was saying in my basic steps post.



NOPE. No need to and no, no one can 'analyze' this log and tell you 'Just never go to this website, never download this program, etc.' do A prevents B steps. The problem is if you get one malware it integrates with others to pull them down based on many things (are they getting paid, is it a friend's software, does it get them more 'cred' with showing how AW3SUM# L33TZ they are, etc.) . So installing any malware will open the door to many others.

The WAY and ONLY WAY to protect yourself is: TREAT THE INTERNET LIKE REAL LIFE.
Whom do you trust when you 'visit' their 'store', the Sears in the Mall or 'Bob's Specials' as he sits hanging out of his van in the back alley? Well that is the same of the Internet, if you visit Internet places that you can't actually 'go to their physical store and SMACK them in the face / let your lawyer serve them papers' then they are NOT a place to trust with your computer.
Sears, Bank of America, etc. you can get up from your computer, get in your car, and go physically to them and punch them in the nose for messing up your computer right? Well where is Willy's Cool ALLFREE Software ? How can you visit Willy? Is that even a GUY? Or named Willy at all? See.. if you can't physically interact then most likely they aren't "trust worthy" just like tBob and his Van in the back alley offering a nice new Sony 60" TV for only $200 cash!

The TV is a LIE and the INTERNET is a LIE. Always recite that and you should keep yourself safe.
