Reduce Windows 8.1 to Windows 7 version
Reduce Windows 8.1 to Windows 7 version
Currently, my brother's system runs an unofficial version of Windows 8.1 since I obtained the license from him—it was a scam. I have a working Windows 7 copy. There seems to be a simple method to revert to Windows 7 without needing backups or formatting the drives.
Make Windows 8.1 feel similar to Windows 7 with simpler settings
Make it hard but just move everything off and change the format.
It's smarter to save vital information from the computer and then prepare the hard drive. This ensures a fresh setup for 7 with no unwanted files lingering.
If you manage this, save the information and perform a fresh setup of Windows. It’s preferable, though it requires additional time.
The link that DimasRMDO posted doesn't apply to you. This is downgrade LICENSE. You said you have Windows 7 license already. You can't downgrade Windows. You need to backup the files, format and re-install Windows and all your brother programs. There is no easier process.
