Thanks again everyone.
I have ordered a new hard drive so I can install XP on it and just go with that.
It's like a full time battle with Windows 7. Even installing VC6 was quite troublesome. I won't waste time describing it, but Windows 7 is generally unhappy when you try to use old stuff. It's pretty clear that MS want everyone to move onto the new system. I can understand that and it is fine for game developers who make "version 1" of their game and then "version 2" which is a completely different product that you pay for again. In our case, where we want to update our existing customers, and there are a significant number of them on an older and perfectly good operating system, microsoft's tactics feel like sort of bullying and pushing us around, whether they intended that or not.
My point is, it's really quite hard developing a product suitable for XP when I'm on Windows 7, which I suspect is mostly deliberate by MS. Deliberate or not, it's difficult so I'm reinstalling the OS which supports what I am trying to do, which is develop LFS suitable for XP. I understand that this will not last forever, and for now I'm keeping my Windows 7 drive available.
On a personal level I have found Windows 7 quite frustrating. It's really bizarre always telling me I can't do things because I don't have permission and so on, although guess what, it's MY computer! Also ridiculous things like every time you do a search, it says "No items match your search." "Search again in Libraries (WTF?) Homegroup (WTF?) Computer (OBVIOUSLY THAT'S WHAT I WANTED FFS!) Custom... (WTF?) Internet (I WOULD HAVE USED FIREFOX FOR THIS!)".
I'm not standing in the way of technology, I just want a computer that is easy to use, when one click or two will get me what I want, not reading half an essay on the screen and having to decipher all sorts of useless information. It's just not for me, and I'm happy to go back to XP and see how long that lasts for me.
