When I got Win 7 Ultimate 64-bit, I split the hard drive into 2 partitions on my laptop.
Was forced to wipe it clean so I reinstalled Vista Ultimate 64-bit and just left it like that. Then I got to work on the Win 7 partition, installing programs and such.
Last night, I booted into the Vista partition and gulped when I saw that it was "bare" - meaning no programs (like AIM, Office, etc) was there - so I spent up until 4 in the morning sprucing it up via installing programs and updates, then cleaning it up .... now it's done.
