Microsoft-minute 

The actual time it takes to download or install data as opposed to the time estimation given in the progress-bar dialog that accompanies the process.

According to this dialog, it will only take two more minutes to install the program. (Five minutes later) The program has to update. Now it says it will take another ten minutes to finish installation. Those are not real minutes; those are Microsoft-minutes!

Microsoft minute

A unit of time whose literal length is constantly changing due to rapid miscalculations of a computer wielding an operating system developed by Microsoft (i.e. Windows 95).

"Say, Benny! How long is it gonna take for this program to install?"
"Well Garrison, it says here just 3 more Microsoft minutes. You never know with those Microsoft minutes, though. It could be another six hours... but if we're lucky it'll only last one!"

Microsoft Minute

A seemingly random period of time required for a (Microsoft) computer system to recognize changes made and begin working properly. This phrase is most commonly associated with Active Directory (Windows Server) applications.

"I just changed your password on the server, so in 15 Microsoft minutes you should be able to log on. If it still doesn't work after 15 minutes wait another hour and it should work then."
