Windows 10: Files getting automatically deleted in Temp folder

Specs:Windows 10 Pro, version 21H2, OS build 19044.2364.Storage Sense is turned off.No 3rd party virus scanners or disk cleanup software installed.Issue: Majority of files in system temporary directory i.e. the path the environment variables TEMP and TMP are pointing to, including files in any subdir underneath, get deleted at times.I'm not 100% sure when this happens but I've got a strong hunch files disappear on reboot. I restart my PC fairly rarely, mostly when there's a series of updates pending installation and one of them requires a restart.Interestingly, the entire subfolder structure

Is it safe to delete the Temp folder in C:/Windows/Temp?

Yes, all *files* in the temp folder (not the folder itself) can, and should be, deleted periodically.

The temp folder provides workspace for programs. Programs can create temporary files there for their own temporary use. Each program should delete all its temporary files when it closes, but for various reasons it doesn't always happen (for example,
if the program crashes, it never gets to do this). That's why it's a good idea to periodically clean out anything left there.

Also note that there are some program installations which work in two steps. The first step concludes by writing temporary files and rebooting. The second step starts automatically after rebooting and needs to find those files there (and then deletes
them when it's done).

Other than doing it automatically when rebooting (that would interfere with installations like the kind I described), it's always safe to delete the contents of the temp folder. Because it's safe to delete any temp files that aren't open and in use
by an application, and since Windows won't let you delete open files, it's safe to (try to) delete them at any time. If any fail to delete because they're open, they'll either be deleted automatically when the app using them closes, or you'll get them the
next time you delete manually.

Some people may suggest that you reboot before deleting anything, but that's not necessary, for the reason described above (on the other hand, it doesn't hurt to do it).
