Vista - This copy of Windows is not genuine

Please Help Guys,

Almost every time I turn on my laptop and log into my account a screen comes up saying something along the lines of Thank You For Validating Windows. This takes up the whole screen and I cannot exit unless I press OK. After my desktop is fully loaded a message comes up saying that Windows Aero has stopped working, you may be a victim of counterfeiting. There is then a link which takes me to Genuine Microsoft Software. I then run the validation test and pass. Also sometimes there is a message in white writing in the corner of my desktop which says:

Windows Vista (TM)
Build 6001
This copy of Windows is not genuine.

My Vista Ultimate is 100% genuine.
Please Help me find a fix which will stop these messages from coming up again.

Call Microsoft support. When did you get it? Where did you get it? Can you call your vendor and ask them why?

Thanks for your quick reply, I would rather not call Microsoft. I got this copy from my School.

Sounds like calling Microsoft would be the easiest solution, provided they even know how to fix it. Why dont you want to call them? If your software is legit, then you should have no problem with them, even if you got it through your school.
Also, you could try reinstalling Vista.

All i can ask of this is why ? ?
They are not the ogres they are made out to be,

Lol to call them i have to tell my dad, I don't really want to tell him that my laptop has a problem cos he will get all stressed.

You got a copy of Vista from your school? Did they give you a proper license to install with it? What OS was on it before? I would consider going back to the previous OS and get it working.

Hey super_js

If you want to continue using Vista the only way out of this problem is a phone call you will probably need your certificate of Authenticity to hand,

I presume that your dad will be a lot less stressed if you explain things to him.

Your only other option is a previously suggested, to go back to your old OS

Pooch

WMI issue could be caused by Vista not being fully compatible with your computer motherboard chipset.

I get the feeling there are important details being left out in this tale of woe...
