When I start Word, Excel, Outlook, or Powerpoint, but not OneNote, a window opens called Microsoft Office Professional Plus 2013 and runs the Configuration Process which takes several minutes. This only happens on one computer. I have tried suggestions from other threads for both Office 2010 and 2013, see my post in:
I added the NoReReg key for all prior versions of Office: 11, 12, 14, and the current 15 (this might have reduced the time the configuration takes - it seems like the progress bar used to run through 3 times, and now only once, but I am not 100% certain). It appears that priority support doesn't look at posts in other threads, but only original questions, hence, I am posting this.
I tried using Process Monitor to find where the configuration information is stored that prompts Office to rerun this process every time, but there were so many similar events that I gave up after trying to filter it down for several hours.
