Wish they would fix this bug

I posted last time and happened a bunch of times and even when I would remote on other clients machines.  It would change the background after I sign out and then copy a picture of one of the machines I was on and puts in the c:\users\user\appdata\local\microsoft\background   or something like that in the folder.  I had another client who did that.  Just dont get how or why it does this.  Its almost as annoying as the commerical use for other home users, but guess they are getting picky about people using the free versions.  I pay for the business license, just hope they fix that changing the background with another one I'm connected to and copying that file in their profile.
