/minimized - Start minimized
When this switch is used only ManicTime tracker will be started, main window will not popup.
/nohw - Disable hardware acceleration
Useful only if main window crashes often. If it does, you can try this argument. It will disable hardware graphics acceleration.
/nostartup - Skip writing to the registry
When it is started, ManicTime tries to write to the registry, to ensure it will be run at startup. Some users don't have rights to do that or have some software installed which prevents writing to that part of the registry and kills the offending app (in this case ManicTime).
This will skip the writing to the registry. Please note that if you use this, ManicTime will not be started at startup and you will have to run it manually.
