Ran into an oddity I thought I would share. After installing and verifying a customer’s Exchange 2013 CU22 upgrade using PowerShell, I handed the servers over to the customer. Sometime in the next week the customer contact me to verify I installed the correct CU. Thinking this was rather strange, he shared a screenshot of Add Remove Programs with it clearly showing CU20 as the installed version. I logged into the server and indeed it was incorrect. PowerShell, however, had the version correct at 15.00.1473.3. I then ran the install in a lab, same result. Add Remove Programs was wrong and PowerShell was correct:
After a bit of research, it appears that this is a known issue:
Exchange 2013 CU22 Shows Incorrect Name In Add/Remove Programs
Checking previous and current releases of Exchange, I do not see any other versions that are like that. Not sure how that slipped through QA, but there are other examples of these little things that slip through Microsoft’s QA from time to time. At least this isn’t a major issue.
