I used this tool and it actually helped me a lot of times to fix broken things, that are nearly impossible to google and repair. Without reinstalling. Lately i had problem with windows update, couldn't turn on update service for some reason. I just repaired pc and i had no corruption. So i run windows tweaking tool to repair windows update and it worked. Strange update wasn't working, after repair btw. And sfc /scannow found corruption, unable to repair it, even dism... I checked cbs log and it was related to windows update components. So it was probably this program, what corrupted it. I don't have any serious issues, i just don't like having corrupted system, because it can lead to various issues, which are hard to track and it can be caused by that.
So i ask again. Is this program safe to use ?
