Probably win 7. That's weird because it is working on my pc with win 7.
It used to work on mine(win 7 pro), BUT, it stopped working. I eventually had to get a guy in to sort it out. He wrote a bash script which deactivated something or other (I know a lot, but I don't know everything - no one can ) and it started working again.
He did tell me why and that windows 7 and vista were prone to it becoming an issue. But, in all honesty it went in one ear and out the other.
It also could be unrelated to your friend.
I have lots of software which makes changes (programming software)
I make lots of changes to windows 7 which could have triggered something.
I run into problems every now and again and I use tweaking.com windows all repair all in one software (its free) and it does what I would have done anyways. It can reset everything back to normal again (from user permissions to that annoying pop up each time you start a program) you get to choose, which suits me.
Wait a bit for Ashley, he knows a great deal, and will give some valuable insight.
