Help - Undo Windows 10 Upgrades?

[ZzBloopzZ]

Hello,

I am out of the loop and need your help. I have a old client I used to support that just upgraded all of his Windows 7 machines to Windows 10 for his company. I told him long ago to stay with Windows 7 since some of his proprietary software he uses only works on W7. I could never get them to work properly on W8.

Is there a way to revert back to Windows 7, or is the damage now done? I honestly do not have the time anymore to help him if that is the case.

Thanks!

I understand that there is the ability to revert within 30 days. Why wouldn't somebody who wants to see how a new operating system works make an image of his drive before upgrading? I have seen problems reported on the windows 10 forum with this go back option.

You can revert anytime you like. However, you would need to leave the Windows.old folder alone.
