10/27/2026, 1:08 PMCurious to know if anyone uninstalled the CPM WMI Plug-in from the VDA install to resolve this: learn.microsoft.com/en-us/microsoftteams/teams-client-vdi-requirements-deploy
_"The parameter is incorrect" error can be caused by other file system drivers. Running fltmc from an elevated command window lists the drivers. Two Citrix drivers (UPMAction and upmjit) can cause the error, even if you're only using FSLogix HotFix 4 and don't have Citrix Profile Manager. This error happens because Citrix VDA installers typically install profilemgt_x64.msi by default for Citrix Director monitoring of logon time counters. Removing that MSI can fix "the parameter is incorrect" error._
I have to assume they mean the WMI plug-in because that's the component that handles the data being sent to Monitor.
