Stupid question - If I choose the upgrade option, will I have to reinstall all my games and such? For cleanliness' sake I usually reinstall Windows every few months or so (I'm weird, I know) but thats (again) on my desktop. The only reason I felt comfortable doing that was because it had 3 seperate drives from which I could choose. I shudder at the thought of having to reinstall everything I have on this, considering I've had it for 7 months without reinstall. Sigh. That would mean reinstalling FF7 (shouldn't take long this time round, it's only the 100th time), FF8, The Sims 2 and all its expansion packs (like 5 hours (only a slight exaggeration)... although I could just leave it considering I now have - ) The Sims 3 (an annoying amount of time). Sigh sigh sigh! This is the problem with having only 1 400GB drive - there's nowhere to put anything when you want to format it!
You shouldn't have to. Everything worked for me without reinstall. Except VMware's Workstation - which does not work with reinstall, either - and Daemon Tools. 7 actually warns you that those are not going to work, and recommends you to uninstall them. I'm not sure, it might have even said that the upgrade won't run from virtual disk (i.e. Daemon Tools), but it does.
Couple of things, though. First, I'm not sure how well the upgrade-option worked in earlier betas. I'd recommend at least the RC. Even so, I'm pretty sure that MS has said that the functionality is not supported. It does work, regardless.
Secondly, the way 7 does the upgrade is that it copies your personal stuff to another drive, installs itself and then restores the said stuff. This might turn out to be a problem with only one drive, and a somewhat small one, at that.
EDIT: Another really stupid question - what's the difference between x32 and x64? I've googled this and came up with a few annoying explanations. What I got from these were that they were coded differently and in one report stated that higher spec systems benefit from using x64. Is that BS?
I have an Intel Dual-Core, 400gb HD, Mobility Radeon HD X3500 and 4gig RAM. Should I use x64?
Really simplified; x64 can address more than 4GB of memory. Well, for practical purposes x86 (or x32, if you prefer) XP will top out somewhere between 3 GB and 3.5 GB. That's because it actually needs a chunk of the RAM to address the display memory. A chunk of
equal size. Or, so I've been told.
Basically; do you do image editing? DTP? Anything with considerable memory requirements? If yes, then you'd want the x64 and more memory to go with it.
The second thing is that x64-software will run only on x64 OS. Whether this is important to you, I do not know, but certain types of software are slowly migrating towards 64 bits, it will take ages before they abandon 32, though. CS4 was the first version of Photoshop to have x64 build, Lightroom has one, PTGui has one... and so forth. If the software needs lots of memory, it will probably migrate to 64 bits, one day.
