I have added over 2000 fonts to the fonts folder Ive been told since that doing this can slow down the start up process, so I would like to remove those I added, however I dont want to remover a system font, so does anyone know which fonts are loaded at set up, Im using windows Vista Home Thank You

It won't make the slightest difference to your systems performance.
I do have to ask why you installed so many though.

Loading 2000 fonts onsystem startup takes less time then it did to type this sentence.

I agree with CurlyBen, I use maybe 5 differnent fonts, why an additional 2000?
