I just upgraded my Vista Home Premium (32 bit) laptop to Win7 Ultimate (64 bit), and so far (knock wood!!) things have gone very well, until I tried to restore my data. This data has lived on my hard disk for a year and a half, I'm restoring from a backup - but it keeps telling me I need more space.
I recall that the upgrade process told me it was going to save the old Windows in a folder called "Windows.old", in case I needed something from it. It did this - and a little investigation tells me the folder takes up around 76 GB of my 136 GB hard drive! 47GB of which is a spare copy of my userid (not including all files). My instinct tells me I can blow this away without trouble, since if something goes wrong with Win7 I'll fix it rather than back off to Vista - I'd just like to run the idea by the community and see if there are issues I'm not thinking of, where I might actually need some of that.
On the same issue, it created a new root-level folder called Program Files (x86). This is a MERE 137MB, but I'm assuming that whatever is in there I can't run on 64 bit anyway, so I can delete it. Does this sound reasonable??
