Microsoft support forums are abuzz with people complaining that Vista boots and launches applications far slower than XP — even though Microsoft said a primary Vista goal was faster boots. Have you noticed Vista booting slower than XP?

I’ve found that Vista boots almost twice as fast as XP. To test it out, I used a Dell Inspiron E1505 laptop with 1 GB of memory. I have it set up as a dual-boot machine, and both versions of Windows are recent installations.

In Windows XP, it takes 45.1 seconds to get to log-in; on Windows Vista it takes only 26.3. That’s quite a difference.

I have several other PCs with XP installed, and several other PCs with Vista installed, but comparing their boot-up times is tough. My XP machines have been around for several years, and have accumulated the usual assortment of startup junk, while my Vista machines are much cleaner. So naturally, on them Vista boots faster than XP.

What have you found — does Vista boot faster than XP, or have you found that XP is the faster of the two. Let me know.
