I upgraded from windows 8.1 to windows 10 and I want back to windows 8.1, but I can't use recovery method because I deleted windows.old folder from my drive.
I have original windows 8.1 (setup files) and serial number,
How to use it to downgrade without losing my apps and files??
"How to use it to downgrade without losing my apps and files??" - You can't, you have removed the ONLY method of doing so. Download the Windows 8.1 Media Creation Tool and install Windows 8.1. This will mean you have to format your HDD to reinstall Windows 8.1 of course. – Ramhound – 2015-09-21T17:20:32.413
@Ramhound ..In disk drive I have two partitions C (for windows) and E .. If I used clean installation, Will the E disk partition be deleted?? – m7mdabuodeh – 2015-09-21T17:29:03.557
The installer only modifies the partition you select. How the installer works has not changed in over a decade. – Ramhound – 2015-09-21T17:30:52.110
