Microsoft’s big Windows 10 rollout is happening all over the world in 190 countries. And maybe you upgraded, or maybe you’re going to wait a week or two before doing it. Something important you need to know is: Yes, you can revert back to your old OS, but there is a caveat.
Reverting Back to 8.1 or Windows 7
Maybe you upgraded, and aren’t quite ready for the changes in Windows 10, or maybe you don’t like it at all. Whatever the reason, you can go back to the previous version of Windows you were running if you want. But, you will only have 30 days to make your decision.
According to Microsoft’s FAQ:
Can I go back to my previous version of Windows if I don’t like Windows 10?
Yes, while we think you will love all the features of Windows 10, you will have one month after upgrading to revert back to the previous version of Windows on your device.
Now, in the flurry of articles coming out about Windows 10, some tech websites are advising to delete the Windows.old folder located in the C: drive to clear space.
I am here to let you know that if you do that, and then decide you want to go back, you can’t. Not without doing a complete reinstall your former version of Windows.
And, if you have an OEM copy (the copy that came on it when you bought your PC) you might end up having to buy a retail copy of the previous version.
If you have any thoughts that you might want to go back to Windows 7 or 8.1 after upgrading – Don’t Delete the Windows.old folder.
It’s probably safe to assume that after 30 days you’ll be acclimated to Windows 10, and have any issues that may have popped up resolved, and want to stay with it. If that’s the case, and you have a tablet or SSD with limited drive space, go ahead and delete Windows.old. But make 100% sure you want to do it.
Here are the step-by-step instructions on how to revert back to your previous version of Windows. We’ll also show you how to delete Windows.old if you need to save space.
But for now, we definitely wanted to let you know that if you want to downgrade, it’s imperative not to delete the folder that contains the files used to revert you back.
