Is there a commandline flag for IE-8 to launch it from the commandline directly into full screen mode?
For anyone else's information, this actually opens Internet Explorer into "Kiosk" mode, with no way to exit other than hitting Alt + F4.
Full screen mode is different and has no argument from CMD, however, can be configured in Group Policy as follows:
Type regedit in RUN dialog box and press Enter. It'll open Registry Editor.
PS: Remember we have covered the same Registry key long time back here?
That's it. Close Registry Editor and restart Internet Explorer. Now IE will always open in full screen mode.
If you want to turn full screen mode off in future, delete all 3 DWORDs created in above steps.
