While we're at it, might as well make some changes like these:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Control Panel\Theme\UserPreferenceWidth
Want 5 row action toggles on your phone? Then this is for you! Create this dword and put a value of 75! This will give your phone that 1520 screen estate, meaning tinier text, tinier buttons, tiny everything!
Change value back to 0 and delete the dword to revert back to default.
HKLM\SOFTWARE\Microsoft\Shell\OEM\SystemTray\DataConnectionStrings\
also in this location is your mobile data status. Fool yourself and or your friends by changing the appropriate string (depending on your mobile connection) to 4G+ or 5G, or even go crazy by showing $$$.
Take note of the changes you make in here, that's the only way to revert back to default without performing hard reset.
HKLM\SYSTEM\Platform\DeviceTargetInfo\PhoneMobileOperatorDisplayName
if you want to show off your awesome carriers name in the about page. More on this
here!
Any additional strings you make in here can be deleted if you don't want it anymore.
HKLM\SOFTWARE\Microsoft\Shell\OEM\ThemeCPL\OLEDWarning
change value to 1 if you want to fool yourself and or your friends that your screen is OLED and if using the white theme, should also show a warning about battery drain on LCD. More on this
here!
Just put it back to 0 if you don't want it anymore.
There are many more! But unfortunately we can't change their values like export to sim toggle and VoLTE swtiches.
Good luck!
