Windows 7, Build 7600, This Copy of Windows is not genuine
I have a Windows 7 laptop. Generally I am pretty pleased with it. Not as pleased as XP, but much more pleased than that claptrap piece of junk called Vista. Windows 7 still craps out occasionally, but a reboot (sometimes removing the batteries to do so) fixes whatever ails it. However, I got a shocker the other day. After re-booting, it told me that my copy of Windows was not genuine. Windows 7, Build 7600, This Copy of Windows is not genuine. What the hell?
Well it turned out that the fix was relatively easy, but still disconcerting. Click on the start menu. Open up All Programs > Accessories. Right click on Command Prompt and click on Run As Administrator.
In the command window, type in: slmgr -rearm
That should fix it. Another reason to think that Microsoft is a buggy piece of crap.
