Machan the easiet way is to first CRACK ya windows in to Genuine. Just search through the forum and u will find loadz of stuff to make it Genuine. The one which worked for me was from SAN_APIIT. Ask it from me in MSN if u want it! Then go to Microsoft.com and download it! Or else just install it! (Assuming u have already downloaded and cant install it!) U will have no problems! Guaranteed to work! Actually it is working 4 me!!
No man! It takes less than 5 seconds man! Both when downloading from Microsoft website (Not really sure whether they validate ya Windows copy when u download WMP11) and when installing!
