Yes, the final update was to get my own laptop to tell me that Microsoft weren't doing any more updates - oh the irony.
I've discovered, according to the link to the upgrade suitability check which someone kindly posted, apparently I can upgrade to Windows 7.
But I've only got 1Gb of RAM on my laptop so I'm not convinced and also I can't find where to get a copy of Windows 7 - half the web-sites I've seen which sell software looked like the "dodgy websites" I was warned about earlier - all flashing buttons and "download now"!
Also, some of the feedback on Amazon from people having bought update versions of Windows 7 tells how they've been ripped off by buying illegal copies accidentally - how do I know what is or isn't an illegal copy? Where is the best place to go to get an upgrade copy of Windows 7, and will there be any point on a laptop with 1Gb RAM?
This is an ubelievable situation - I've got an old, but perfectly functional laptop and I'm having to look at getting rid of it. Not right - thanks for all the help though, it's much appreciated.
