Is there any recent changes implemented by microsoft with respect to the temp folder access.Due to this few application that uses the temp are not working as expected . **********kindly refer the attached image ************************************Note: I know how to take ownership and gain access to my accounts.I need to know the behaviors changes that has been implemented .: s

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).

 

Original owner of "temp folder" in C: Drive

Hi Patrick

Click your Start Button, then just type cmd

From the resulting list, right click Command Prompt and choose 'Run as Administrator'

Paste this into Command Prompt and hit Enter

icacls "C:\Windows\Temp" /t /q /c /reset

When that command completes, close Command Prompt, that will have reset permissions and owner on that folder . . .
