I'm with Tony on this, if it isn't broke don't touch it, I would think you would/could introduce more problems by doing this. Obviously I/we would recommend backing your machine up before you proceeded, and if you're going to do that you might as well get a nice clean install on board from the off

Here is a Microsoft guide to the differences, ignore the salesy stuff they include though.

Differences

From this list key ones that may impact a home user would be:

Multi-processor support (could you see yourself running dual processors in your home machine? Some high-end gamers do ....)

Security - do you have your own network at home with other PC's in which you share files/folders between them? If you do their are other administrative benefits that could apply such as roaming profiles/GPO's etc - but you need a domain to leverage these.

Multi-lingual UI pack - do you have people using this PC that are multi-lingual who would want this feature?

In short, unless you need anything on that list I'd leave it how it is.

:D

cheers - leave as is then!!

Now another question....webspace, where can I get some cheap or free.

Been trying to upload pics to my ntl space but it comes up not allowed or out of memory and I cant update it!! Been using ACE ftp3 s/ware which I downloaded

If you just want space for pics I use photobucket.com. Free!
