But it spent at least 3 hours when I upgraded from Vista Ultimate x64 to Windows 7 Ultimate x64. The machine is a Core 2 Quad 2.66hz with 8gb RAM. Obviously it was no joke when Windows 7 setup said the upgrade may take several hours. At the time of the writing of this sentence, it was still being upgraded, forcing me to use another machine to blog.
The final step of the upgrade - Tranferring files, settings, and programs - was the most time-consuming, took over 2 hours in my machine. And it showed that there were 1,003,453 items to be transferred. I wonder what constituted these 1 million items. One registry key = one item? Maybe I really have that many files.
I ran the Windows 7 Setup from within Windows Vista. It warned me that SQL Server 2008 may not run properly if I upgrade without uninstalling it first. After some googling I decided to follow the advice and uninstalled it.
Seems like most settings from Vista are left untouched after the upgrade. Unfortunately there is one big problem - all my pinned programs in Start menu were gone. I have to repin those programs. Anyone experienced this?
