I used CCleaner to clean the registry, made a back-up, rebooted to black screen, restored the registry backup, still broken.

Things i've tried:

System restore
Startup repair
Booting in safe mode
Rebooting multiple times

I have windows installed twice on my machine, such that prior to booting windows I'm asked to log onto

1. Windows 7
2. Windows 7 (recovered)

I used my Windows 7 recovered to access the registry backup and restored it from there.

I have Windows 7 Ultimate 64bit.

I would value anyone's help.
 
Solution
I would get into windows (however you can) backup critical data to cd or external device, then erase and reformat your hard drive, then do a fresh install of win 7. Good Luck.
Do not use registry cleaners. Registry cleaners pick and choose which registry keys to delete, and this leaves gaps in the registry. The kernel time savings in passing over deleted keys is insignificant, and in fact, may take longer. Sometimes the registry cleaners "guess" which keys to delete, and sometimes they delete valid keys, thereby rendering the affected programs corrupt.

Don't use registry cleaners.

Don't use third-party file cleaners. Sometimes the files are completely legitimate and take less than 2% of disk space, the deletion of which is insignificant in disk head operations and file searches. Use only the disk cleanup utilities that comes with Windows, or your operating system. Sometimes, the third-party cleaners also delete valid files, causing corruption in the normal operations flow of your computer, creating far more problems that it solves.

Don't use third-party file cleaners.

Don't use registry cleaners.

If you want to speed up your system because you think it is slow, then run msconfig in the command bar, and see which startup programs you can uncheck so they do not run on startup, each of which cuts into your kernel processing, thereby slowing your system down. Essential background services only on startup, the rest on manual, since they can be run at will after the system has booted. For example, I have only one startup program, and that is DVD play. All others on manual, not loaded at startup. On average, I have 80% of my memory free because of this.

My boot up time from power up to logon screen: 21 seconds, with Windows Vista SP-1. SP-2, after I installed it, only served to slow everything down to where I had to do a clean reinstall with the factory settings, uncheck all unnecessary startup programs, and essential services only. Power down time is about seven to eight seconds. Sleep time is about two seconds. All because I have all unnecessary services on manul, not running in the background, not eating up cycles.

I do not use Norton or McAffee anything. I use only Windows Defender, the firewall and MS security essentials. All scans come up clean. My system has never run faster nor more efficiently.

Do not use registry cleaners.

Do not use third-party disk cleaners.

Defraggler by Piriform is okay, though, I've never had any issues with that.

Windows disk cleanup utility works just fine and only deletes files that knows will not cause any problems or system crashes.

Leave the registry alone unless you know EXACTLY what you are doing.

System slowdowns are not caused by old registry keys from deleted programs, or even old files that aren't used any more, but too many startup programs running in the background you can fix yourself with msconfig from the search bar on the start button (if you have a start button). The program marketers don't tell you this because they want to make money from you and make you think you have an infection, like "1183 issues fixed". LOL. Most of them are non-issues and do more harm than good in removing them.

Don't be fooled. Leave well enough alone. Less is definitely more. Do not overclean.

Now, you are informed. Have a wonderful day!
 


With anything Windows, I do this every six to nine months routine. Then I turn updates OFF and leave them OFF. Updates, cleaners, too many startup programs, all are the problem. Just factory settings for me from a fresh reinstall.

I just love that!

I have been downloading and installing programs from here for a while now. I don't just install them and delete them if I don't like them I still play with them for a bit to see how good they really are. I LIKE almost everything about cCleaner EXCEPT after prolonged use with XP Pro and XP home and Windoes 7 the power options under the start menu WILL no longer work or be there, also Ctrl-Alt-Del will no longer work and the computer pops up with this message "Ctrl-Alt-Del has been disabled by you system administrator" there is a few other possible problems like the occasional Black monitor but I do not remember them at all this moment. I work and build computers and I know from experience that I will never use it again NOR will I recommend it. I have tested the power options and Ctrl-Alt-Del problem on other computers and same outcome. I myself had to reload Windows over 6 times due to these problems. could just be me but use at your own risk. Now you have been properly warned.
I was told a month ago to try CCleaner, So I downloaded and started cleaning, After I was done Eset Securities found 3 trojans in the CCleaner. I tried to uninstall CCleaner and then attempted to remove the trojans. My screen went black keyboard locked up but system is still running. I have a 4 core system with 32gigs of ram and 2 terabytes of storage and a 7980 Video Card. While in DayZ or Day of Defeat now after about 5-10 minutes of play my screen goes black my keyboard locks up and I must reset the system to get it to work. I didn't have this problem Before I downloaded CCleaner !!!
You've all be warned.
