A user came to me with this laptop, he said his powerpoint is not working, when he open an existing powerpoint, it’s very slow to load that powerpoint. I tried all my troubleshootings, clear MS office Temp files, remove add-ins , repair , re-install MS Office, but it still didn’t work.
My last try was to create a new windows profile for him, and it worked perfectly.
So, my thought is: if user is having problem with Office, creating a new profile for him/her is the best way. It might take more time, but it should work.
