I wouldn't waste my time with
Vista as it is a heap of sh1t.
76% of American businesses are using
XP, which in my opinion is better than
Win7 which has so much crap added on.
1. My suggestion is to download
Windows XP SP3
2. Download small software to make Windows XP SP3
Genuine
3. Dowload
Driver Genius to get all the required drivers.
4.
Disable Windows Updates ( believe me the updates are not required )
If you need help with links for downloading let me know and I will certainly help you.
Cheers
