7′s computer maintenance will delete all broken network shortcuts if you have more than 4 of them on your desktop. If the computer loses connection to the drive for whatever reason, then icons that point to the network drive letter get deleted because they are “broken”. Here is the work around.
Go to C:\Windows\diagnostics\scheduled\Maintenance and edit the file TS_BrokenShortcuts.ps1. You may have to take ownership of it to edit it.
Comment out lines 12-21 by putting a # in front of each line. Save.
This basically returns a blank list so that no shortcuts get deleted when they get “Broken”.
