Can play on it again?
No. Unfortunately, it's not that easy. The programs are stored in the registry and other libraries. The simple backup on a stick only works with individual programs… But you can try it!
No.
The entries in the Windows registry are then missing and most programs do not run.
But are there other options?
If you want to reset your laptop because something is not working (blue screens, etc.), you can also do a repair installation, while the files and programs are preserved. Simply download the Windows Media Creation Tool and select "Upgrade".
No, at least not a sensible option.
You will need to reinstall them.
No.
