Just to clarify, when I meant upgrade I meant it in the coloquial sense. I did the usual format and install not use the upgrade option on the disk.
Why back to XP? I left that behind about 5 years ago! Jumped over to Beta 2 of Vista, then the RCs and finally released Vista Ultimate which hasn't been touched since it was installed at release.
System is an x2 4400 with 2GB RAM and plenty of storage space. Never had a major problem that I can remember with with Vista, especially since SP1 and SP2.
The problems I'm having at the moment are slow file transfer speeds (across disks in the machine) also causing the machine to crawl to a halt (even when the transfers are being done over disks the OS isn't installed on) and a variety off annoying little bits like that, culminating in me trying to resize an jpeg image in Paint last night (haven't got round to reinstalling PS yet) and it locking up the entire computer. Managed to finally get the task manager up and tried to kill the process, resulting in the Paint process increasing ram usage massively and me hard resetting the machine.
7 also seems to be using more RAM than Vista at startup (with only MSE and mesh), not that it bothers me too much, just I wasunder the assumption that 7 would actually perform better... Still running a tight ship at the moment with only a couple of games installed, a few small programs and MSE, all of which were installed on the previous install.
TBH I assumed this would be the response but I just wanted to check as I quite like the new style of vista as well as one or two of the new bits (although quite a few are a pain in the ****) especially homegroup which is a massive plus in a house full of Win 7 machines.
