Solved is it safe to remove Temp folder before Windows update?

Hey everyone!
I have changed the "C:\Users\***\AppData\Local\Temp" and "C:\Windows\Temp" directory to my HDD which is "G:\Temp\"
then I created a .bat file with this code:
then added the .bat file to Group Policy / User Config / Windows settings / Scripts / Logoff
So, whenever I click on restart or shutdown, Windows will run disk cleaner and then clears the G:\temp subfolders and files.
is it safe to click on restart after a Windows update? Does windows update store files in temp folders during an installation? or it's better to deactivate the .bat file before updating to make sure it doesn't ruin the update...
any suggestions?
thanks.

Disk Cleanup (cleanmgr) will only delete temporary files with a last access timestamp older than seven days, as indicated by the LastAccess value in the registry...


That's a perfectly safe thing to do. Cleaning the temp directory entirely every reboot seems excessive.

WU uses its own staging folders to download and extract updates. It doesn't care about any other folders that exist.

Cleanmgr wants to clean files up, because it's designed to clear enough disk space to allow a major Feature upgrade to run. Windows doesn't want a pending update/upgrade blocked simply because it ran out of disk space on C:\.

The normal Windows temp and user temp folders are targeted, simply because there's an understanding those are allowed for periodic cleanup. While cleanmgr runs in order to help WU, WU is indifferent on how it gets done except that nobody touches WU's staging folders.

Thanks dear Pseymour.
Yea I think so... it's excessive. I'm developing an engineering software with python which works with Simulia ABAQUS and I have to use the temp folder a lot. so I have to clean it twice a day at least!
My question is about Windows update. I'm afraid cleaning user or windows temp breaks the update I don't know
