Solved Re-installing WinXP, it no longer accepts the 25 digit code.

Specs: Windows XP Home, Cerelon 1.8gHz, 2GB Ram
I had to format the power interruption damaged hard drive and re-install Win XP Home from the same disk and 25 digit code that succeeded in Feb, 2009. Now it will NOT accept that code as valid !! How do I activate Win XP Home with a single registry entry change? I know it is possible, and easier than all other options.

I don't think that this site is going to tell you how to bypass the protection mechanisms built in to Windows. Phone the Microsoft activation phone number.

Seems odd to me that a hard disk change affected activation. This normally only happens if the CPU or motherboard are changed. Phone MS activation (as already suggested), they will probably be able to help in this situation.

Always pop back and let us know the outcome - thanks

"I had to format the power interruption damaged hard drive"
Did you delete all the partitions? when I have problems, I find deleting & a FULL ( not Quick ) format to NTFS is the best way.

XP - D to Delete the selected partition

I had that problem once or twice when installing 98. It turned out that either the hard drive or cdrom had failed during the install ( I can't remember for sure but I think it was the hard drive.) Setup still thought everything was OK but it couldn't verify the key because the device the algorithm was on had failed so it gave the 'invalid key' error.

When you're installing XP, if the license number isn't working, there's information right on the screen telling you how to Contact Microsoft to activate Windows.

It took a while for the whole Full (NOT Quick) format, (CDR) Win2000 install, (CDR) WinXP UPgrade "do-over", but it solved the problem.

BTW, the "0" to "1" registry change solution was written in a help column of a PC type magazine to speed up the hassle of the whole WinXP re-install procedure. There was no nefarious intent, but it sure seems to have enabled it. That tip is somewhere in my massive torn out pages stack of useful articles. I remember checking my registry entry in 2009 and it indeed was a "1" entry.

MS catches on in a hurry if some simple hack precludes authenticating your copy of XP. Jennifer told you how to do it in #6.
