The Liquidware Container Service installs in minifilter mode by default in ProfileUnity 6.8.3 when using Windows 10/Server 2016 and above.  This can be reverted to legacy mode, which was the default used in ProfileUnity 6.8.2 and below. 


Upgrade to newest version of ProU, post 6.8.3 and this issue is corrected.


From the \\server\netlogon\ProfileUnity (or the share you have the ProfileUnity client delivered from) copy the file to your folder on your local desktop.

Open/extract the file ContainerService\x64\VirtFsService.exe.config from the archive.

Open the file VirtFsService.exe.config in a text editor and add scroll to the bottom.

Look for the following MiniFilterMode entry and modify this from True to False:

      <setting name="MiniFilterMode" serializeAs="String">


Save the file and place it back into the archive overwriting the existing file in the archive.

Place the back in \\server\netlogon\ProfileUnity (or the share you have the ProfileUnity client delivered from) overwriting the existing

When LwL.ProfileUnity.Client.Startup.exe (as defined in the ProfileUnity Computer GPO section) runs next time, the Liquidware Container Service will be installed in Legacy mode.

**Make sure only the file contents in the archive are zipped back up to prevent an extra folder ie.. flexapp\flexapp\files..**

Existing Installs

In the base image, uninstall the ProfileUnity client.

Reboot machine.

Run LwL.ProfileUnity.Client.Startup.exe with the configuration change outlined above for new installs in place.

Note:  The filter mode can be verified post configuration change by running fltmc.exe from an elevated cmd prompt on the client vm.  This will look as follows when set correctly to legacy mode


You can also use the 6.8.3 linked file that already has the changes made.   Just remove the .renameme and copy in place of on client tools network path.
