Adb restarting on Windows 7 machine

Hi guys, my apologies for starting this new thread but I tried searching and couldnt find my issue.

I just bought a new laptop with Windows 7 and I set up ADB and after every command it tells me its out of date, killing, then it restarts and runs the command. Everything works properly because I unrooted my phone using it like this, but it didnt do that on my Vista laptop. Anyone else having the same issue, I'm about to root again and I'd like to get it working properly before I do this. I set up the environmental variable thinking that might be the prob, but it didnt help. Thanks you guys!

Well if anyone else has this issue, it was because HTC sync was running in the system tray. I closed it and the problem is gone
