REM   -taskadd    = add autorun of autoupdate.bat on startup in schedule task
REM   -taskremove = remove autorun of autoupdate.bat on startup in schedule task
REM
REM Info:
REM   The autoupdater first use and check the official rdpwrap.ini.
REM   If a new termsrv.dll is not supported in the offical rdpwrap.ini,
REM   autoupdater first tries the asmtron rdpwrap.ini (disassembled and
REM   tested by asmtron). The autoupdater will also use rdpwrap.ini files
REM   of other contributors like the one of "saurav-biswas".
REM   Extra rdpwrap.ini sources can also be defined...
