Forced to Reactivate Windows after Hardware Change?

Windows Genuine Advantage (WGA) is an anti-piracy system enacted by Microsoft that enforces Microsoft Windows online validation of the authenticity of several recent Microsoft operating systems when accessing several Microsoft Windows services, such as Windows Update, and downloading from the Microsoft Download Center. Specifically, WGA covers Windows 2000, Windows XP and Windows Vista. It does not cover Windows Server 2003 or the Windows 9x family.
What hardware gets checked?

The WPA system checks ten categories of hardware:

1. Display Adapter
2. SCSI Adapter
3. IDE Adapter (effectively the motherboard)
4. Network Adapter (NIC) and its MAC Address
5. RAM Amount Range (i.e., 0-64mb, 64-128mb, etc.)
6. Processor Type
7. Processor Serial Number
8. Hard Drive Device
9. Hard Drive Volume Serial Number (VSN)
10. CD-ROM / CD-RW / DVD-ROM

It then calculates and records a number based on the first device of each type that was found during setup, and stores this number on your hard drive. Initially, this is sent to Microsoft in an automatic dial-up, together with the Product ID number derived from the 25-character unique Product Key used in setting up Windows.

If Service Pack 1 has been installed, the entire Product Key is also transmitted: This can then be checked against a list of known pirated keys

The hardware is checked each time Windows boots, to ensure that it is still on the same machine. Also, if you subsequently perform a complete format and reinstall of Windows, Microsoft’s activation center will have to be contacted again because the information held on the machine itself (the number previously written to your hard drive) will have been wiped out by reformatting the hard drive. If your hardware is substantially the same, this will be done by an automated call without your needing to talk to anyone.

What does ‘substantially the same’ mean? WPA asks for ‘votes’ from each of these ten categories: ‘Is the same device still around, or has there never been one?’ Seven Yes votes means all is well — and a NIC, present originally and not changed, counts for three yes votes! Minor cards, like sound cards, don’t come into the mix at all. If you keep the motherboard, with the same amount of RAM and processor, and an always present cheap NIC (available for $10 or less), you can change everything else as much as you like.

If you change the device in any category, you have lost that Yes vote — but will not lose it any more thereafter if you make changes in that category again. So, for example, you can install a new video display card every month for as long as you like

The Wga status is in the file “WPA.DBL”. How many YEs votes you have?

To find that you just need to use XPINFO.exe.
You will get it from http://www.licenturion.com/xp/.

Now the TIP:
1)After making a small hardware change like youve changes the cdrom so youve lost 1 vote.
2)Then check the status of wpa.dbl with XPINFO.exe You will have 1 no vote
3)Then delete the wpa.dbl from system32 folder(there will be a backup wpa.bak for emergency)
4) Reboot System It will complain about the licence
5) Reactivate though the internet to obtain new wpa.dbl
6)Then check the status of wpa.dbl with XPINFO.exe You will have all yes votes.
The advantage is that if you didnt do this the you will have to activate through phone~!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
