    I have a little problem sometimes where certain files will just change format; for example, a couple of word perfect files all of a sudden became WMP files; they're just text files, why would this happen?! It doesn't seem that serious but I've had so many stupid problems over the years it just makes me lose confidence in the computer (again) and think I'll be back to having a haywire machine. Any ideas what would cause this?

    From what I can find so far, that is a Windows Media Player file. I have no idea why that would be happening! :confused:

    If they still open with Word Perfect while doubleclicked, it's just an Iconcache problem, and nothing to worry about.

    Delete the 'ShelliconCache' file in your Windows folder.

    Subsequently, reboot.
    Windows will automatically recreate the file.

    NOTE: You need to be able to view hidden files to see the ShellIconCache file: click Folder Options on the View menu in Windows Explorer, click the View tab, click Show All Files, and then click OK.

    You can also try the 'repair icons' option in TweakUI.

    Afterwards, in order to diminish the chance of the problem recurring, increase the size of your Icon cache:

    Copy the following bold text to Notepad:


    "Max Cached Icons"="2048"

    Save as Icons.reg, doubleclick it, and have it merged into the registry.

    Good luck,
