Can't roll back to Wds 8.1 from wds 10 ..

Hi All
It's not even a week when I upgraded to wds 10 ..
Now It won't let me roll back ..
When I fo to Recovery .. and click roll back ..START .. It keeps showing wds can not find the files to go back even if WINDOW OLD still in drive C "main" drive ..




The only way to roll back is to restore factory settings ..

Any helps ..appreciated ..

Thanks

This is when you realize how important doing an image backup before upgrading is

How big is the Windows.old folder? Maybe things have been deleted from it?

You could download a Windows 8.1 ISO and use it to create a flash drive or DVD to install 8.1 from, especially if the recovery doesn't work. Windows 8 and Windows 8.1 ISO - Download or Create

I count too much on what MS said " 30 days " .. " Dawn you MS " ..
I can go back to wds 8.1 any time , just that it will take me long time to install all the programs and settings the way i like ..

Hmmm, this is fior Windows 7, but might also work for Windows 8:

I don't think it will work with 10 ,
It's so ok ..I will stick around with wds 10 for awhile ... and pick a weekend to reinstall 8.1 ..

Thank you for your help

Wouldn't hurt to try it since you are going to clean install 8 anyway. Would be nice to know if it does work, could help others in a similar situation.

Definately ..I will try that first ..
Thanks .

The following conditions may cause the computer can't rollback from windows 10 to windows 8.1:
Create a new account
Remove the $Windows.~BT and $Windows.~WS folders required by the system to perform the rollback operation.
tried other reduction / restore factory settings function
Remove the verification file installation
after a month of upgrading to Windows 10
See Windows 10 -- : windows
His Windows.old still there, check if it is the same reason:
Found the reason why it happened - The answer is most likely because I used the media creation tool to download a second copy and make a bootable USB. However that second copy apparently replaces the original windows upgrade folder (~BT).
