All those itchy hands or had automatic updates, went to upgrade
and facing problems with WMP11... you've got some help.
Please note that this only
applies to XP. If you are using other systems (by right you
shouldn't, whatever way you got WMP11 installed, I don't know how
to fix).
Another note: Please do not run CCleaner, CleanUp!, ATF Cleaner or
any other cleanup programs. If you do so, then you won't be able to
roll back. Do it after you've successfully rolled
back.
Part 1
Please also make sure that you are part of the Administrators
group, whether or not your logged in name is Administrators.
To check, go to Start > Control Panel > User Accounts.
Your logged on nick should be under Computer Administrators as
shown in the picture below (blue box):
If you can't find User Accounts icon, look on your left.
You will see Control Panel with two arrows pointing upwards.
Click on Change to Classic View (see image below,
brown box).
Now, if you are not part of the Administrators group and is using
XP Professional, there's a way to get pass.
Go to Start > Log Off. Select Log Off, don't switch user.
Press Ctrl + Alt + Del twice.
You will shown a log in box.
Type in administrator
The password should be blank.
Press Enter to log in.
For XP Home users, go to Start > Shut Down.
Wait for 30 seconds. Then boot up your system again. When you see a
screen asking you to press some buttons (Del or F2 or whatever),
press F8. Keep pressing F8 till you get into a screen that shows
you the Safe Mode option.
Use the up down arrows to select Safe Mode. Press Enter.
Wait for XP to load.
Once it starts, select the Administrator account, NOT your usual
account.
The rollback starts now!
