Increase or decrease system font size

Decreasing the system font size can show more content in the same screen area. Similarly you can increase the font size to increase the readability.

Go to Start -> Settings -> System tab -> Screen -> Text Size tab and move the slider around.

As mentioned there, the font size change is not guaranteed to work for all applications as many apps keep their own font values, overriding the system defaults. It also does not seem to work on text inside menus. The technique should however work on most microsoft inbuilt applications.

Stop ActiveSync from asking Partnership selection

One of the annoying things about ActiveSync is that it asks for Partnership (Standard or Guest) to be selected when a connection is established, for e.g. on new devices. If you are a developer and are continously establishing Activesync connection with a device, it can be very annoying to close the selection screen every time.

Solution is to add a registry value, GuestOnly under [HKLM\Software\Microsoft\Windows CE Services]. and set its value to 0x01. This will force Guest as the selected partnership mode.
Once the device syncs in Guest mode, it will always do so.
