Quick overview:
After you have cleaned up the System File Protection folder as described in this trick, you can now limit it to a certain size for the future. I recommend a maximum size of 100 MB.
Click one after the other on Start > Execute and type it into the command line sfc /cachesize=100 in. After clicking Enter, the limit for this folder is set and you no longer need to worry about precious storage space.

NOTE FOR NEW PUBLICATION: This article was produced by Sandro Villinger and comes from the Windows Tweaks archive, which has been built up since the late 1990s.
Founded Windows Tweaks as a teenager in the 90s. His helpful PC tricks made it Germany's most visited Windows site (at the time Sandro looked like this). He then went on to write elsewhere, for example for PC-Praxis, Computer Bild and PCWorld in the USA. Microsoft also poached him from us. Now Sandro is back, finally sharing his tweaks here again. For a stress-free digital everyday life. You can reach Sandro via e-mail.
