Hello, I’m Virginia a fellow Windows user.
The best way to backup is to use a disk image. This will save a snapshot of your pc as an disk image, then should a problem occur you can use recovery media or the program’s recovery drive to restore the image.
Windows has its own backup & restore but this is a deprecated feature so may have problems.
Microsoft recommend using third party software:
“System Image Backup (SIB) Solution
We recommend that users use full-disk backup solutions from other vendors.”

If Windows 7 backup & restore is not working for you in windows 10/11 then you may have to consider moving to third party solutions or use File History & OneDrive which just backs up certain files & folders.
Of the two I would recommend disc imaging software.
I use Macrium Home but there is a free version still:
Direct download link:

Or download here:

AOMEI backup free: https://www.aomeitech.com/ab/standard.html
EaseUS backup free: https://www.easeus.com/backup-software/tb-free.html
These have their own boot media which can be created on USB or CD in case of failed drives & with Macrium this can also be added to Windows boot list as a choice during boot up
