Windows 7: "This copy of Windows not genuine" even though it is.

Hello. I've purchased an Acer Aspire M3202 a little over a year ago with a free upgrade disc to Windows 7. Over the past year I've had no issues, but recently out of the blue I keep getting repetitive dialogs saying that my copy of Windows 7 isn't genuine even though it is.



I've run the "genuine check" online application only to have it say it would disable some of my features, so I quickly closed out of the application. So far my computer seems unaffected other then that annoying dialog popping up every few hours. I have blocked its process using a process blocker but would like to solve the issue completely.

Have you made any changes to the hardware of the computer? Sometimes hardware changes can cause Windows to think it is on a different computer and thus not licensed properly.

Yeah, actually, installed a new graphics card. Any tips on how to fix it?

Hello Avery,

You might see if you may be able to activate by phone instead.

Hope this helps,

I agree, that's generally what you have to do. Usually you have to talk to someone over the phone, you can explain the situation to them, and they have the ability to give you a special code that will allow you to activate Windows again (as I'm sure it says in Brink's link).

Little problem though, I can't open "slui.exe", I have disabled all my process blocking utilities and restarted to no avail, UAC is also not blocking it. It just won't open.

Did you type slui.exe 4 instead?

Yes, also to no avail.

As a test, do the tutorial once below to reset activation to see if you may be able to activate online or by phone afterwards.

Activation Trial Period - Extend Up to 120 Days

I'm a little cautious, if this doesn't work will Windows 7 loose most of its functionality?
