Use the following registry edits to change the 2 Home screen softkeys.
You can modify the Right key that is currently Lock to point to s2u2.exe instead of devicelock.exe.
Left SoftKey
HKLM\Software\HTC\manila\HomeLSKPath
Example: \Winodws\Start Menu\Program\Text.lnk

Right SoftKey
HKLM\Software\HTC\manila\HomeRSKPath
Default is: \Windows\DeviceLock.exe
