"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.
