XP Pro Activation After Windows Update - Error Code 0x8004050a

[Flash999]

After connecting to windows update the other evening and downloading WGA &
IE7 along with other updates my computer asked me to activate windows when it
re-started.

It could not connect to the internet now for some reason so I used telephone
activation.

I then typed in the activation code and the computer returned error code:
Problem with Windows Activation : Error Code 0x8004050a and computer logs me
out.

Please don't give me the following advice :

1. Contact MS - As I've got a support number and they have pointed me here
or KB.

2. Try starting in safe mode - I've tried that but it still asks for
activation

3. Re-Installing XP Pro - For some reason it will not start my XP Pro disk
even with the 1st boot device set to CD-ROM. It does start up my old laptops
XP Home Edition disk thus allowing me to go into Restore but even though I
did create a restore point prior to updating cannot get rstrui.exe to run.

4. Try posting on WGA forum - They claim the problem is nothing to do with
them. Although there are similar posts going back 10 months there.

5. Try posting in IE7 forum - same as answer 4 above.

6. Tell me to install XP Home then run the XP Pro as I've acquired mutiple
devices since buying this laptop 5 years ago and don't want to re-load all
the drivers.

7. My copy of windows XP Pro is genuine. I do have a COE.

8. The computer had been running quite happily for the last 5 years before
this set of updates.

Wipe the hard disk with a utility from your hard drive manufacturer's
web site like MaxBlast5 before attempting to install XP.

Then, once you have XP installed, DO NOT GO TO THE WU WEB SITE! Set the
computer to notify but not download or install updates and DO NOT ACCEPT
THE WGA "update".

I wouldn't install IE7 either.

Try disabling the firewall to see if that makes a difference

Alias,

Too late it's already on there and that's what's causing the problem. Last
resort is to start from scratch.

Ron,

Can't get into windows to turn off the firewall.

Also since posting I have tried another legit copy of XP Pro I have but the
Laptop does not seem to see the XP Pro disks only the original XP Home that
came with it.

I added the 2nd Product Key, got the installation Id, phoned MS and got the
A to G codes and same error as before :

"A problem is preventing Windows from accurately checking the license for
yjis computer : Error Code 0x8004050a"

Does anyone know how to recover a restore point from restore console boot ?
