Re-Activation for Windows XP
Should you restore your system to a point before you activated XP
on your computer, the OS will forget that you activated it and
you'll need to reactivate XP. If the system restore point is past
the 30-day grace period that Microsoft allows for activation,
you'll have to activate XP immediately.
The only workaround to reactivating your system is to perform the
following steps:
Start your Windows installation in Minimal Safe mode.
Move to the \%systemroot%\system32
folder.
Rename wpa.dbl to wpa.noact.
Rename wpa.bak to wpa.dbl.
Reboot your system as normal.
Note: The above procedure will work only if you've made no
significant hardware changes.
Like i said as per above, how do I go into the start-up screen
with the notebook unable to function properly.
