1. Back up all of your data files.
2. Create a Restore Point.
3. Download the 434MB 5-language file from
http://tinyurl.com/32z6vj
4. Start > msconfig (as administrator).
5. Under Services tab, check the Hide all Microsoft services box.
6. Under Services tab, Disable all.
7. Under Startup tab, Disable all.
8. Reboot.
9. Install the SP1 download - expect 30-60 minutes with 2-3 reboots.
10. When complete, go to msconfig as administrator again, restore the
Services and Startups you wish to run, or under the General tab select
Normal startup.
You're finished.
If you encounter any conflicts, use msconfig to suppress the startup or
service causing it, and seek the latest driver, file, app, etc.
If you cannot get an updated file/app/driver that is compatible with SP1,
and you must have that function, roll back. Sorry...
No warranty with this advice, though I was successful on three
recalcitrant computers that should have updated the simple way, but
wouldn't. They run fine now, showing 6001. Good luck to you, and please
report here.
