New Recovery Tool to help with CrowdStrike issue impacting Windows endpoints

RobYork  thanks, no worries.   I tried to handle it in the code below, in case it helps anyone.   For now, we're trying to detect Bitlocker encryption on or off based on the "manage-bde -status" command and parsing output looking for the "Lock Status:"   If its "Locked" I then parse the "Volume " line of the output to get to the drive letter.  If there's multiple drive letters this won't work well.  Maybe there's a better way, since we found the manage-bde -status output to be limited in the Windows PE environment with encryption enabled.   

If the target computer isn't using Bitlocker encryption, the batch file loops through drive letters A-Z and finds the one where CrowdStrike exists.  That seems to work pretty consistently.   This isn't fool-proof but hopefully someone with better .bat file skills could enhance it.    Thanks, Bruce  

7/22:  I haven't done .bat files in decades a colleague noticed I needed a "setlocal" at the beginning to clear variables.  Also, the parsing of "manage-bde /status" doesn't seem to work in the WinPE environment so this approach is flawed.  

setlocal
cls
@echo off
for /f "delims=" %%a in ('manage-bde -status') do ECHO.%%a | FIND /I "Lock Status:          Locked" > Nul &&  GoTo BitLockerOn
GoTo BitLockerOff

:BitLockerOn
for /f "delims=" %%a in ('manage-bde -status') do ECHO.%%a | FIND /I "Volume " > Nul && for /f "tokens=2" %%i in ("%%a") do set word2=%%i && set drive=%word2%
echo Using drive %drive%
echo If your device is BitLocker encrypted use your phone to log on to https://aka.ms/aadrecoverykey. Log on with your Email ID and domain account password to find the BitLocker recovery key associated with your device.
echo.
manage-bde -protectors %drive% -get -Type RecoveryPassword
echo.
set /p reckey="Enter recovery key for this drive if required: "
IF NOT [%reckey%] == [] (
	echo Unlocking drive %drive%
	manage-bde -unlock %drive% -recoverypassword %reckey%
)
Goto DeleteLogic


:BitLockerOff
for %%D in (A B C D E F G H I J K L M N O P Q R S T U V W X Y Z) do if exist "%%D:\Windows\System32\drivers\CrowdStrike\C-00000291*.sys"  (
	set drive=%%D:
	echo Using drive %drive%
	echo.
	Goto DeleteLogic
)

:DeleteLogic
	del %drive%\Windows\System32\drivers\CrowdStrike\C-00000291*.sys
	echo Done performing cleanup operation.
