Windows 7 - Microsoft: Windows 7 upgrade can take nearly a day

While developing Windows 7, Microsoft ran a ton of different performance tests to make sure the operating system was an improvement over its predecessors. One of the tests focused on upgrade performance: 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. Microsoft gave three reasons for using the Vista SP1 to Vista SP1 upgrade as a baseline instead of Windows XP to Vista:

Well that's pretty ugly. I was thinking of performing an upgrade the wife's laptop, now I may want to rethink that.

Twenty hours and 22 minutes for a heavy user upgrade on medium hardware. I wonder how many MS testers commited suicide

Nice post 7dreams thanks

That is scary.

No one is going to want to wait that long.

I would hope someone with THAT much data would have it on a separate partition while having the OS on its on drive

Yeah Mine Took 2 Hours, with only 20gb.

In fact, If I would have a 1.5TB hard drive and one of them, I would have all my data on it. Then, I would say "OMGGGGGGGGGGGGGG how will I update?!" But, If I wanted it, I would be in that category. But that's not the case and there's actually much more data on my hard drives than on Microsoft's tests. Like ~700GB.

And, yes, I'm keeping most of my files on my different hard drives. For various, obvious reasons :

1. Data security.
2. If there's a problem with the OS, a quick copy of the User folder on an other folder and we are ready to go.
3. OS upgrade time
4. No more huge quantity of DVDs

I always prefer clean install for a new version of windows to make it as close to how MS intended it to run as possible. If you have bits from previous versions in the new install, it must affect it in some way.
