Hi
I upgraded to Windows 10 Pro just over 2 weeks ago from Windows 7 Pro. Since then my PC keeps crashing and performance is very poor and, despite upgrading various drivers and (and downgrading some too) nothing has made it any more stable so I decided to roll back to Windows 7 which used to work absolutely fine. I have followed the procedure to roll back (http://windows.microsoft.com/en-us/windows-10/going-back-to-windows-7-or-windows-81) and my PC reboots, gives me a black screen with the Win 10 logo, reboots again straight into Windows 10. I've tried it a few times, it does that every time. No error messages on screen, nothing in Event log to say there's an issue. The event log shows that the shutdown was successful and the boot into Win 10 was successful, it doesn't show anything related to the attempts to roll back to Windows 7.
I haven't deleted/changed any of the files required to roll back.
I've booted into the Windows 10 troubleshooting tool and also attempted to "Go back to previous build" where I'm prompted for some admin credentials which i provide and it starts the process but a very short while later it reports "We ran into a problem and won't be able to take you back to the previous build. Try resetting your current build instead".
The upgrade to Windows 10 disabled the system restore point process but I enabled that and have about 4 Win 10 restore points and earlier this evening I restored to the first one I created about 2 days after upgrading as suggested by an article i found on the web. That restore worked fine but it still wouldn't roll back to Windows 7. I then tried to undo the restore (Windows said it was possible) but then reported that it failed to complete it and no settings had been changed.
I am really regretting my decision to upgrade.
Please, does anyone have any suggestions on how I can roll back to Windows 7? If I have to, I can do a clean install of Win 7 and all applications but that's a very time consuming process and I'd much rather be able to roll back to the Win 7 install I had before I upgraded.
thanks for your help
