You appear to have a few applications running that are in search of these files. MS Transcriber is related to Pocket PC software.
I would ask myself a question if I were you, have I uninstalled any programs recently or deleted any folders related to this software?
When ever I start Windows XP Pro, I get several boxes that appear. They are UDF Formatter, DrvmCDBpending IO, Dispatch\Tfsnifs, Dispatch\??\TFSWIFS, DrvmCDB, and Diagnostic Traces. I also get a bos that says Microsoft Transcriber. Can any one tell me why and how to eliminate these from appearing? Thanks
