Hey welcome to computerhope.com
, now sit down for the bad news!
I hate this as much as anyone, the old-days are over !
We used to borrow software from friends and put it in our computers and bammo, were good to go! Not anymore, with Microsoft products anyway!
Once, a
Windows Operating system is downloaded and installed in the (1st.*) computer, its done with... You cannot legally use it again... Legally.....
When windows does its automatic updates now days, a new "patch" installed is looking exclusively to make sure your operating system is yours and yours only...
Windows Genuine Advantage << thats the patch name... there are MANY articles on the internet (do a google search, etc..) and you can read up on this subject...
There are ways around this problem you are having I am sure, I don't know how to tell you to do it though but, you run the risk of having your operating system not allow you to connect to the internet in the future and maybe worse... Microsoft will be enforcing this new security of rights tool soon in all pirated copies of Windows...
Save up some bucks and buy a legal cd when you can, piece of mind*
