Windows A common topic of discussion in the Windows world - in fact, in any operating system - is boot performance. Many systems take a long time to reach a usable desktop from the moment the power switch is pressed, and this can be quite annoying if it takes too long. In a post on the Engineering 7 blog, Michael Fortin, lead engineer of Microsoft's Fundamentals/Core Operating System Group, explains what Microsoft is doing to make Windows 7 boot faster.

Blaming only OS (Windows or other) for slow boot times is actually nonsense. BIOS loader and hardware initialisation (both by BIOS and Windows) tend to take sometimes more time than OS loading.

Recently I built home PC with optional Vista boot. Initially it included one HDD and no USB devices; BIOS+Vista booted for about 25-30 seconds and Vista shutdown took about 4-5 seconds. Not bad IMHO.
Afterwards I added 2 more HDDs, tuner card and some USB devices. BIOS stage duration increased to about 20-25 seconds, BIOS+Vista does start about 50-60 seconds (same for BIOS+XP). Vista shutdown remained to 4-5 seconds though ;)

Because I boot my PC rarely, I've not investigated, what to change in BIOS (newer BIOS version perhaps), what devices to replace or what drivers to block to make boot faster. I've even not optimised Vista yet - I'm mostly using XP.

On one forums I read about very slow POST - about one minute - for some motherboard. After disabling some monitoring same motherboard did POST for 15 seconds...

If OS developers could optimise devices loading time, it would be good. If hardware manufacturers (and BIOS writers) could shorten initialising times, it would even better ;)
