I installed it today.
First thing that happened is BSOD right in the middle of the installation

I guess that caused all the problems that followed.
So I tried again,this time about 20 minutes into the install I got an error.
Sorry I dont remember the code but I googled it and tried the solutions,none worked.
Here is a screenshot of one failed solution attempt.

I hadnt really done anything with Vista that could have caused these problems(as far as I know).No tweaks or hacks or anything like that.
But never fear I found a solution.
Re install Vista and apply the service pack.
It worked.
How much of an improvement is it?
Who knows all that messing about took a few hours and once it was done I went back to XP.

I will post again with my thoughts after I have installed all my programs again.For tonight Ive had enough.
