WMRegOptimizer is a freeware application for Windows Mobile Pocket PC devices that optimizes the registry of Windows Mobile- in other words, defrag it. It lowers latency for certain system calls, which may result in better responsiveness in some situations resulting in somewhat faster registry access for applications and executables where there is a bottle-neck.

Before running WMRegOptimizer, ensure to:

- Close all running applications
- Uncradle the device
- Put the device in flight mode
- make sure battery is not low

After the program finishes the job, close it and soft-reset the mobile device. The program may appear to freeze at times. Do not soft-reset or terminate it but let it continue. The entire process may take up to 5 minutes to complete.
