Here's the best solution:

1) open notepad

2) copy the below text into notepad:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionWPAEvents]
"OOBETimer"=hex:ff,d5,71,d6,8b,6a,8d,6f,d5,33,93,fd
"LastWPAEventLogged"=hex:d5,07,05,00,06,00,07,00,0f,00,38,00,24,00,fd,02

[HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersion]

"InstallDate"=dword:427cdd95
"ProductId"="69831-640-1780577-45389"
"DigitalProductId"=hex:a4,00,00,00,03,00,00,00,36,39,38,33,31,2d,36,34,30,2d,
31,37,38,30,35,37,37,2d,34,35,33,38,39,00,5a,00,00,00,41,32,32,2d,30,30,30,

00,00,12,42,15,a0,00,08,00,00,87,01,00,00,00,00,00,00,00,00,00,00,00,00,00,
00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,94,a2,b3,ac
"LicenseInfo"=hex:9e,bf,09,d0,3a,76,a5,27,bb,f2,da,88,58,ce,58,e9,05,6b,0b,82,

0a,0a,ce,0d,b8,27,4a,46,53,f3,17

4) go to 'save as' option

5) in the drop down menu of 'Save as type', select 'All files' not 'Text documents(.txt)' otherwise it wont work

6) save the file as 'WGA.reg'

7) double click on the file and click on 'yes' and then on 'ok'.

8) go to microsoft's genuine validation site and validate your pc:

http://www.microsoft.com/genuine/default.mspx?displaylang=en

9) now your pc is 100% legal and validated

enjoy!

note:- if you wont validate from microsoft, you would have to open this file each time you reboot
