How To: Disable Ctrl/Escape ?

Go to:
\HKLM\SOFTWARE\Microsoft\Shell

Make new DWORD Values as follows

DisableCtrlEsc DWORD 0
EnableStartButton DWORD 1
HideTaskBar DWORD 0

How To: Speed up device display ?

You can change the memory used to cache fonts glyphs, this allow you to use more memory to speed up the display.

Go to:
HKEY_LOCAL_MACHINE\SYSTEM\GDI\GLYPHCACHE\

You can change the “limit” value :
4096 : slow down the display, but use less memory (default setting on Palm-size PC)
8192 : default value on Pocket PC, average memory/performances
16384: speed up the display, but use more memory, twice the default Pocket PC value will be 32768

How To: reduce the amount of time your device is on when it wakes up for an alarm ?

We can reduce the amount of time for 180 to 60 seconds saving energy in this way.

Look for this key:
HKLM\SYSTEM\CurrentControlSet\Control\Power

And change the value of WakeupPowerOff from 180 to 60.

Go to:
HKLM\ControlPanel\Password

If you have any Redirect rename it to xRedirect.
