You can use System Restore to roll your system back to a point before the update was installed. You won't lose any personal files, but any programs installed or uninstalled in the interim will be reverted. Open the Control Panel and select "Recovery." If you don't see the "Recovery" option, select "Large icons" or "Small icons" from the "View by" menu. Select "Open System Restore" to open the System Restore utility. Restore points are created automatically when new programs or updates are installed. Depending on your System Restore settings, you may have many restore points or just a few. Old restore points are deleted automatically to make room for new ones. You may be able to check a box in the lower-left corner to view all available restore points. This will generate a list of all of the programs, drivers, and updates that will be removed or restored when rolling back. Programs and drivers that are restored may need to be re-installed to function properly. Once you click "Finish," your computer will reboot and roll back to the restore point. This may take a little while to complete. After your computer successfully rolls back, Windows will start and a dialog will appear indicating that the restore is complete. After restoring, see if getting rid of the update file fixed your problems. You'll likely need to re-install or uninstall any programs or drivers that were restored during the roll back process. If the system restore process doesn't work, or makes things worse, you can undo it and revert your computer to how it was before restoring. Open the System Restore tool again and select "Undo System Restore" to undo the last system restore you performed.

summary: Open the System Restore tool. Select the restore point you want to roll back to. Click "Scan for affected programs." Confirm that you want to perform the restore process. Test your computer. Undo the system restore if problems occur.

This "clears" the lock of any previous numbers. If at any point in putting in your combination you mess up, do this again to start over. Turn the dial to the right and stop at your first number. Always start with a turn to the right! For your second number, turn the dial to the left, going past zero and your first number. Then stop at your second number. Some locks are a bit odd or finicky -- if your locker isn't opening after you put the three numbers in correctly, try turning left past your second number once and stopping on it on the next go around. For your third number, turn the dial to the right and go directly to the last number. Leave your lock on this number. Always remember: right, left, right. Pull the lock open and out of the hole, or pull the latch or handle, if there is one. Otherwise, tug on the knob to open the locker. If your locker just won't open, try it again with the last number being five before or after your "official" last number. Sometimes the older locks get, the shakier they get in their requirements or abilities. If that doesn't work, ask your classmates or teacher if there are any similar quirks in the school locker system. Try twice before you call a teacher. Make sure, if you have a locker with an unattached lock, that you lock your locker when you leave. If you don't, it's possible your things will get stolen or your lock will be turned backwards. Close your lock up and twist the dial a bit. If you leave it on the final number, it may open up again effortlessly, for someone other than you.

summary: Spin the dial at least three times to the right (clockwise), all the way around. Enter your combination. Open the lock. Lock your locker after use.
