6 When the device reboots it will automatically launch Regedit. Click "File | Import" and then locate the "Mnav" folder in the files and folders selection list and double click to open. You will see the "modified.reg" file copied in step 4, double click to import.
7 Delete the renamed "regedit.exe (e.g. mnavedce.exe) in \mnav (or rename it)

9 Copy "showtaskbar.exe" from the .zip file and paste into \Windows\Startup
10 Locate "explore.exe" in the \windows folder, right click and select "Create Shortcut". Cut the "Shortcut to Explore.Exe" file that is created as a result and paste into \Windows\Desktop. Repeat this process for "MNAVDECE.exe located in the "Mnav" folder and "MP3Player.exe" located in \Windows
Finally reset your device once more with the stylus and it will boot to the WinCE desktop with shortcuts to the three applications you had before
