How not to do, fourth edition

Task is to re-create user profile on Windows 7 operating system.

So here is the steps i do:
Log out the current user who is somehow pretty buggy.
Log in with user who has administrator rights.
Go to c:\users\
Rename Andy to Andy.old
Log out the administrator
Log again with Andy. Everything is fresh and clean :)
Move all documents from Andy.old to Andy
Everything is working, continue living :)
.. but NOT in long terms!
One day after windows update the new Andy can be gone.

And again this is not how to do things!
