My friend has just bought a new computer that came with Windows XP HOME addition already installed.  Somebody else took the computer and installed simply accounting on it.  I'm not sure what happened after that, but now when you reboot the computer and the login screen comes up I get this error. "A problem is preventing Windows from accurately checking the license for this computer.  Error #0x80090006.  I can no longer log into the machine any longer. It keeps popping this message up.  I can however login in using safe mode which I don't quite understand why.  Any ideas?

Hi plexus1,
"Error 0x80090006" When You Restart Windows XP After You Restore Your
Computer from Backup

SYMPTOMS
When you restart your computer after you restore Windows XP from
backup, you may receive the following error message:



A problem is preventing windows from accurately checking the license
for this computer. ERROR 0x80090006

CAUSE
This issue may occur if you replace a hard disk, and then restore
Windows XP to the new hard disk from a backup. When you restore
Windows XP to a new hard disk, the hardware ID for the restored
Windows XP computer changes. The new hardware ID prevents the
computer from verifying the license correctly because the hardware
hash no longer matches the hardware hash that was used for the
original product activation.
RESOLUTION
To resolve this issue, after you restore the computer from a backup,
perform an in-place upgrade of Windows XP, and then reactivate the
Windows XP license.

First try system restore,

when in safe mode, try system restore to restore to an earlier time, and see if that helps, probably it will uninstall the accounting software that you have just installed, but the data will still be there.

If you turn off system restore, you have to use the Windows XP HE CD to do repair.

Set your BIOS to boot from the CD ROM. Then put the XP CD in the drive, as if you were doing a clean install.

You have to choose 'install windows' on existing drive then 'repair' option as it goes through the hdd to check the existing windows installation.

That should fix it.

Post the result to us again to see how you go.

Cheers.

I got it fixed.  Thanks guys.  Funny thing is that it didn't ask me to repair the installation, it just went right ahead and reinstalled Windows.  It was a brand new machine anyway so I didn't lose any information.

Thanks,

Luke
