Using System Restore is a better option than to create a registry backup. Still, if you want to create Registry backup, here’s what to do:

Open Registry Editor by typing regedit in RUN (Win Key + R).

Now, on menu bar click File | Export

Remember to click on ALL (in Export Range) (This will back up the WHOLE registry), before you save.

Now just name the file and click save.

Give it some time to save it.
