The operating systems on PDAs are different from the normal PC ones. The operating system is stored in the ROM of your PDA, and when you do a hard reset to your PDA, the windows is reinstalled from your ROM. And if there is no ROM upgrade for that particular device by directly from it's brand (sadly there is no ROM upgrade to any other version of windows for that device), you cannot upgrade your device's windows version. There is something called "Cooked ROMs" in the internet containing newer versions of windows, but they are illegal and risky. Anyway, your PDA is designed for that version of windows, including hardware, and newer versions of windows may not work correctly or completely slow down your PDA.
