Running Vista on a Sony Vaio - constantly getting error message pop up about a missing .dll file : QTCF_CFHTTFMessageSetHeaderFieldValue. What can I do to find/fix this problem?

Running Vista <- There's the 1st problem.
on a Sony Vaio <- There's the 2nd.

Ok I kid. QTCF almost sounds like QuickTime something-or-other. All Vaios come shipped with so much crap installed it's a wonder they boot up at all. It's probably something that it shipped with.

If you want the easy fix, decrapify your machine so that it only runs the apps you want to install.

IF you want to find the culprit, use MSCONFIG and choose selective startup. ON the startup tabs you can pick and choose what apps to launch at startup. This will be a massive trail and error effort as you select a few items to launch, test, repeat... until you can identify the bad app.
