Error 0x80041002 from PowerShell after upgrade to Windows 10

On a box I just upgraded, we run a script that’s supposed to add a new scheduled task. After the upgrade, attempting to create a new trigger would return this beauty:

PS C:\Users\User> New-ScheduledTaskTrigger -AtStartup
New-ScheduledTaskTrigger : Method "NewTriggerByStartup" not found
+ CategoryInfo          : ObjectNotFound: (PS_ScheduledTask:Root/Microsoft/...S_ScheduledTask) [New-ScheduledTaskTrigger], CimException
+ FullyQualifiedErrorId : HRESULT 0x80041002,New-ScheduledTaskTrigger

The solution was to run this magic batch file that re-registers a whole slew of DLL files with the system, and then reboot.

net stop winmgmt
c: 
cd %systemroot%\system32\wbem 
rd /S /Q repository
 
regsvr32 /s %systemroot%\system32\scecli.dll 
regsvr32 /s %systemroot%\system32\userenv.dll
 
mofcomp cimwin32.mof 
mofcomp cimwin32.mfl 
mofcomp rsop.mof 
mofcomp rsop.mfl 
for /f %%s in ('dir /b /s *.dll') do regsvr32 /s %%s 
for /f %%s in ('dir /b *.mof') do mofcomp %%s 
for /f %%s in ('dir /b *.mfl') do mofcomp %%s 
echo DONE

I found the batch file here, intended to fix another issue with the same error code.
