Netropa's MMKEYBD.EXE and OSD.EXE are used for Dell's Enhanced Keyboards with media buttons. The two executables stay in memory. When adding these two executables to ProcessGuard and on system reboot, Windows XP-SP1 Home will load, start to activate programs, flash a BSOD, and reboot again and again and again. I can delay MMKEYBD.EXE startup, say 5 seconds, using StartupDelayer and the system will boot up fine with no problems. Do you want me to e-mail you these two executables for evaluation?
