:: Safer WMI Repair and Diagnostic Script
:: Version 2.0
::
:: This script provides an interactive menu to diagnose and repair the
:: Windows Management Instrumentation (WMI) repository. It follows a
:: phased approach from least to most invasive actions.
::
:: IMPORTANT: This script should be run with elevated privileges
:: ("Run as Administrator").

echo This is the recommended first repair step. It performs a consistency
echo check and, if an inconsistency is found, rebuilds the repository
echo while attempting to merge data from the old repository.
echo.
echo Stopping the WMI service and its dependencies...
net stop winmgmt /y
echo.
echo Running the salvage operation...
winmgmt /salvagerepository
echo.
echo Restarting the WMI service...
net start winmgmt

echo --------------------------------------------------------------------
echo If the repository is now consistent, test your applications.

echo --- [3] Re-registering WMI Components and Recompiling MOFs ---
echo.
echo This is an aggressive repair. It will stop the WMI service,
echo re-register all WMI-related DLLs, and recompile all standard
echo MOF files in the WBEM directory.

echo Disabling and stopping the WMI service...

echo Re-registering all provider DLLs (this may take a moment)...
:: This loop uses corrected syntax to iterate through all DLLs.
for /f %%s in ('dir /b *.dll') do (
echo Registering %%s...
regsvr32 /s %%s
)
echo DLL registration complete.
echo.
echo Recompiling MOF and MFL files (excluding uninstallers)...
:: This command creates a list of MOF/MFL files, filters out any
:: containing "uninstall", and then compiles the files from that list.
dir /b *.mof *.mfl | findstr /v /i "uninstall" > moflist.txt
for /f %%s in (moflist.txt) do (

echo Re-enabling and starting the WMI service...

echo!!! --- [4] WARNING: DESTRUCTIVE OPERATION AHEAD ---!!!
echo.
echo You have selected to RESET the WMI Repository. This is a
echo "last resort" option that will delete the current repository
echo and restore it to the state it was in when the OS was first
echo installed.
echo.
echo POTENTIAL CONSEQUENCES:
echo - Third-party applications that use WMI (e.g., antivirus,
echo backup agents, monitoring software) will likely break.
echo - A full reinstallation of affected software may be required.
echo - All custom WMI configurations and data will be lost.
