should these files be removed?
They are not Windows files so yes... the msdadmin folder is strange, have you got some kind of CentOS running?
Windows 8 only has one app (
I know of) that puts stuff in the temp folder and thats the Microsoft store... this file should not be removed because it can cause an issue with the store kicking you out.
Most the time the legit files in temp are 3rd party software; firewalls, anti-virus, Adobe etc in sort any software that syncs to the internet will tend to dump files here and thats fine because its the way Windows was designed to work... all of these files can be removed without issue if the software isn't running at the time you try to remove them... thats also why most...
