How can I get my system to stop thinking Cakewalk\vstplugins is the default install loc?

Some manufacturers use the value in HKEY_LOCAL_MACHINE\SOFTWARE\VST\VSTPluginsPath as the default install location. Some maintain their own value in the registry.

Seems like every vendor has their own scheme for persisting the install location. Even worse, a few don't even bother and simply default to \program files\vstplugins, steinberg\vstplugins or a top-level folder called vstplugins (lookin' at you, u-he; it's not 1995 anymore).
 
After ending up with duplicate DLLs on several occasions, I just gave up and now let those lazy vendors stick 'em wherever they want. Even though c: is my smallest drive, VSTs just don't take up enough space to warrant fretting over.
 
Far more impactful is where sample libraries go, so that's all I worry about. I make sure there's at least enough room on c: for the initial install and then move them (pet peeve: why do vendors even bother with installers for Kontakt libraries anyway? Gimme a zip file, I'll figure it out!).
