I'm having occasional problems with NTFS permissions on a Windows 10 PC, especially when installing programs.
I guess it started when I created a new user for myself some time ago and deleted my old user, after a certain program failed to install, also because of a permissions problem.
Since then, I have occasionally tried and manually changed permissions here and there in case of access problems. In the meantime I have learned that one should not do this (unless you know exactly what you are doing).
Now I'm looking for a way to reset all permissions on the entire system partition to factory defaults.
As I have learned, this seems to be possible with the command
Secedit /configure /db Secedit.sdb /cfg C:\windows\inf\defltwk.inf /overwrite
However, before I unleash that command onto my system drive: could doing this possibly also go terribly wrong, or should I expect any severe side effects, respectively?
