I decided today to reset my Windows laptop because it is getting slow, I can't remove Avira and Widnows updates keep failing. What data is now important except for my personal data (I just put all these folders, photos, videos files and my personal data on a hard disk). Are there any other important files that I should back up before resetting?
If you have secured the personal you know your passwords you can reset it.
You should save documents that you need at work / school. You also need a USB stick with windows on it or a CD to install windows. Otherwise no further files are required
It would be better than resetting to completely reinstall Windows with a new key. And format the hard drive completely.
What should be different with a new key? Except that I have to spend money again
