A Microsoft Software Engineer has posted the results of tests the company performed to the upgrade time of Windows 7. The metric used was total upgrade time across different user profiles (with different data set sizes and number of programs installed) and different hardware profiles. A clean 32-bit install on what Microsoft calls 'high-end hardware' should take only 30 minutes. In the worst case scenario, the process will take a bit 1220 minutes. That second extreme is not a typo: Microsoft really did time an upgrade that took 20 hours and 20 minutes.
Microsoft wanted to make sure that an upgrade from Vista SP1 to Windows 7 was within a five percent threshold faster than an upgrade from Vista SP1 to Vista SP1.
