Fail 1: My Windows was activated right after it was online. I'm not sure what kind of personalization you want. I don't see what Windows 8.1 can do but Windows 10 can't by default.
Fail 2: You can change the search engine as stated in the previous post.
Fail 3: You need to uninstall driver completely first. Windows will not auto-install drivers right after driver is uninstalled because you shouldn't be online at that time.
Fail 4: What kind of control over updates you have? Windows 10 Pro can defer upgrades.
You need to be more specific about your problem to get help. Your problems can be resolved; just look up.
On the other hand, my problem is weird even though it doesn't bother me much. My Mouse Properties dialog is slow to open. It takes about 1-2 minutes for the dialog to open after clicking on Mouse in Control Panel.
I asked Microsoft community and searched everywhere, but found no solution. This IS a problem.
The my windows activated ~2 hours after upgrading to it (which isnt that much of a problem, however it was annoying as most options were locked for me until it activated. Those options include changing options in Edge and changing the color scheme. I stated that (atleast to me) it looked super ugly with the black task bar and white texts on it. after 20 min looking at it my eyes started to hurt. Im not sure why windows didnt choose to make the default colors similar to what they are in older versions.
As for the drivers. When i installed windows 8.1 (i have to add i made completely clean install) It did picked up alot of things from the personalized windows i had (task bar on the right side, wallpaper, kept my drivers - yes it did automatically installed same drivers i had on windows 7) while on windows 10 i had to go to computer management->device manager and remove 5 times the network adapter choosing the option "delete the driver files too" and it kept popping up after device scan with the same sh1t driver that always gave me error code 10. Up untill i removed the device installed the correct driver and then scanned for new devices
I couldnt find any option there... just one that would let me choose between automatic restart and planned restart or something similar. Also it looks more hard to navigate than the previous versions but im not gonna b1tch about it as it is expected to have some menus changed
Overall for someone who dealt with the beta version it might not look that way but for a new user it is frustrating
(Anyways im just stating my current opinion and if there is options or menus i missed please feel free to point that out)
