[b:cbe8e44ad8][color=green:cbe8e44ad8]So far, All the PC's I've had in my shop too work on, Everyone asks me to take Vista Off. 
Only PC's I've had major issues removing Vista from were the Toshiba laptops. They don't offer any drivers for XP :evil: 

My wifes best friend Installed Microsoft Office 2007 on her Toshiba Laptop running Vista Premium and It messed it up.
She Ended up taking it to Geek Squad since if anyone else works on it, her Warranty would have been Voided  :roll: 

I've had more PC's come in from Geek Squad that were so messed up, It's pathetic 8O 

One a lady spent $200 for them to fix Her HP tower, It kept shutting down.
After getting it back, and it was doing the same thing, she brought it too me.
When I took the sides off , there was a inch of dirt in the cooling fans, and wires.  wack 
The power supply was so full of dirt, I had to take it apart, and clean it out. :? 
It's been 4 months now, and It's running like New, so she tells me :)   [/color:cbe8e44ad8][/b:cbe8e44ad8]
