Speed your Windows Mobile with registry tweaks

with 3 comments

This set of my registry tweaks is believed to be a must have, it optimizes and enables various caches and thus gives significant performance gains. There are also few neat tweaks to make your life easier. Current set of tweaks was prepared for custom Windows Mobile 6.1 ROM by kva, however these values should work fine on any Windows Mobile device.

Improve graphic layer cache performance


Change the value of ‘limit’ from 8192 to 16384, 32768 or 65536 can be used as well but thats an overkill.

Increase Font Cache


Values same as glyph but currently this doesn’t show any gains so leave 0.

Enable file cache







Speed up SD Card Transfer







Change ‘BlockTransferSize’ from 64 to 16. This makes SD much more responsive with 4x faster read times!

Enable IE faster caching


Internet Settings\AggressiveCache=1

Remove Wireless Manager icon from right-bottom corner of today


In our case Keep = 0 doesn’t work so I change the filename of WlsMngSrv.dll in this reg key to sth like WlsMngSrv.dllxxx. You can delete the whole key as well but it’s easier to get back to it if you would ever need to. You can still load it from programs menu or assign a hardware button.

Today bottom keys

Create the following keys and strings in the registry:



112 is the left key and 113 is the right. Now for each key create two new strings for example: Default=Notes and Open=\Windows\notes.exe

Clear Type for horizontal mode


Note that 0 is enabled and 1 is disabled!

Enable Cleartype in Pocket Internet Explorer


Internet Settings\ClearTypeText=1

GPRS/EDGE keep alive

Change this if you constantly need internet access and don’t want to wait for connection to establish. It doesn’t drain your battery as this is only a GSM network state flag and nothing is transferred, so there is no way why you shouldn’t use this. The device is simply prepared to send/receive data. This also prevents the red phone button when pressed from closing data connection.



Connections\*your connection name*\AlwaysOn = 1

Change Wireless Manager to default WM style

This will revert default Microsoft Wireless Manager which is much cleaner and faster than Eten’s. You will need an initWiFi script though… so this trick is for advanced users only. Run Windows\wrlsmgr.exe to see how it looks.



Disable SMS threading in WM6.1

Create binary value:



SMS Delivery notifications

Messaging -> Text Messages -> Menu -> Tools -> Options -> * Text Messages -> and then just tick at “Request delivery notifications.

Soft reset the device and enjoy!
