disable plugin scan at audacity startup

question from a newbie: running Audacity 2X on WindowsXP,Audacity exe.download,install from there.
how to disable plugin scan at Audacity startup:suggestions/instructions howto please.
thanks in advance.
btw,unchecking scan box under preferences not working.

Edit menu > Preferences > Effects.
Disable (uncheck) VST effects.
(If the scan occurs each time that you start Audacity it is because you do not have any VST effects installed, so you don’t need Audacity to keep looking for them).
