I upgraded a 32 bit Win XP to a 64 bit Windows 7 build without a hitch, but
this doesn't contradict anything the KBs say. I did not use an "upgrade
disk." I did not do a "clean install," but again I did not use an upgrade
disc. I used a full Win 7 Premium. However 2 points to remember that are
obvious.
I) You are not going to upgrade to or install a 64 bit OS on an X86 or 32
bit box.
2) You may have to install as the MSKB says by starting the pc from the 64
bit OS--I think I had to do that. But it prompted me to restart which I
thought was nice because MSFT is getting better and better about not leaving
things between the lines for setups--cheers to them for doing that. I have
also noticed that the upgrade option in Win 7 and I suppose Vista will now
tell you what the roadblock is if it balks at upgrading and this is a very
nice feature and the guys and gals on the teams that designed this should be
commended for doing this.
When I installed from a Vista with Windows One Care, they for various
reasons won't allow or have designed things so that One Care won't install
on Win 7 so the upgrade link produced a message after checking my system
that I had to uninstall One Care and it would allow me to install Windows 7
because One Care isn't compatible with that. This is a nice touch/feature
and it is the most attentive work I've seen so far from MSFT to coach you to
get the upgrade in. It's nicely done.
What I can't put my finger on (although in the past it has had to do with
the expansion of files that does not require as much space) is why a 3.5 GB
OS (Win 7 64 bit) would require at first on one box on one previous build of
Win 7 a 11+GB free space piece of real estate and then subsequently a 16+GB
piece of real estate to allow the upgrade to happen. Hopefully, this won't
be present as they move toward RTM.
