USMT workaround for BGInfo desktop wallpaper

Posted on Updated on

If you use BGInfo on your computers and migrate a user’s profile to a new computer, you’ll soon discover that the BGInfo of the new computer is overlaying BGInfo from the old computer, creating a very ugly desktop wallpaper.  The reason for this is that once BGInfo executes, it generates a new image from what the user had previously set for themselves.  Fortunately, the original image file’s location is stored in the registry as well.  The below script that I created is designed to run prior to USMT (while no user’s are logged into Windows).  It essentially mounts each user’s registry hive, grabs the original file from the registry and then resets the Wallpaper value for that user.

There is one caveat to this process however.  If within USMT you’ve set /uel:X to excludes user profiles older than X number of days, using this script will cause those profiles to now be recently logged into.  So before using this script, be sure to cleanup any old user profiles that you do not want migrated.

Workaround for KB2444193 with USMT 4

Posted on Updated on

There is a known issue when migrating to Windows 7 with USMT.  If a computer is deployed using an AutoUnattend.xml, then after migrating a user to the new computer, when the user launches IE they receive the message “A program on your computer has corrupted your default search provider…“.  One workaround is to have a script correct the SearchScope GUIDs for each user profile.  The script that I have written (below) simply mounts each user profile hive, then deletes the registry tree for the SearchScopes.  The effect is that when the user first launches IE 8, then it will pull the default Search Provider from HKLM defined in the deployed computer via AutoUnattend.

Excluding file types within MigUser.XML

Posted on

For an upcoming upgrade of our computers, I had a request that during the user migration that only desktop shortcuts (.lnk) files be backed up and migrated and no other files.  It took several failed attempts to get working correctly, but the process I finally found that works was to do the following:

  1. Edit MigUser.xml
  2. Find section with comment “This component migrates Desktop files”
  3. Within the objectSet of “<include filter=’MigXmlHelper.IgnoreIrrelevantLinks()’>”, change the pattern type line to the below:

    <pattern type=”File”>%CSIDL_DESKTOP%\* [*.lnk]</pattern>

  4. Save the MigUser.xml (of course!)
