A question to u.. chirayu garg Are you using a genuine copy of XP. If your answer is some what close to yes, read below.
Hi.. this issue is well known as your computer is velneralble to new WGA(Windows Genuine Advantage). This is happening to alot of ppl.
The Windows Genuine Advantage tool runs from Windows Update automatically, & has been know to generate a "This copy of Windows is not genuine" error on legitimate Windows XP installations. On systems that are getting this message, have them navigate to the weblink below, & run the manual WGA validation to resolve the issue.
goto this MS site and validate manually.
