Move the CHM files to the local drive or globally set the desired
restriction at login.

Thanks for your help. But, moving the CHM files to the local drive is not
feasible as workstations need to open each CHM file individually.

Please explain in detail " How the desired restriction at login can be set

Thanks in anticipation.

If you have a domain, you can set the required change to run at logon as
part of a logon script; otherwise you'd need to set it to run before logon,
probably using the HKLM\Software\Microsoft\Windows\Current Version\Run
registry key to load the edit you need.
