Isn't it true having more fonts makes Windows slower?

Isn't it true that the more fonts you have installed, the slower Windows will run (no matter what program you're in)?

Thanks

Windows will take more time to load.

I'm not sure if programs launched afterwards will also suffer from this.

After a google search it seems to say it will also use system resources once windows is loaded.

I was asking because my friend just told me "I've just installed 6000 (six thousand) fonts"

So I asked why in the world he would need all that and that it'll just slow down his PC. And he said well my PC is fast, so I said then why dont you remove the 6000 fonts you'll never even use 0.5% of, and sell your PC and get a PII 300mhz with 128 mb ram, itll run just like his 2200+ orwhatever cpu he has with 1gb ram.

Anyway, after quoting a bunch of google results that say it will significantly slow down and waste resources he removed them.

Yeah, clicker, and there was actually a 1k limit for windows in earlier versions (and I assume one of your links points to such a detail now, right?), but you could create a separate folder to "store" the excess ones. Never made sense though: just keep them on the darn CD's.

Actually most sites said anything above 300, others said 800, would significantly waste system resources.
