A quick question about GMod's compability

I’m getting a new computer soon that has windows 7 on it instead of the one I currently have on it with windows vista on it. I just looked on the GMod page on steam and noticed that it only listed windows vista, XP and 2000 under the system requirements. Does this mean GMod won’t work on windows 7 or will it still work?

I’m running 64-Bit Windows 7 and Gmod runs fine.

It’s 100% compatible.

Indeed that is true.
I’m using it on my laptop with these specs:
AMD Sempron 2.4GHz
140GB Hard Drive
ATI Radeon HD 4200 128MB
Windows 7 Home Premium 64 bit
