Windows More news on Windows 8. This time around, Gabe Aul, a director of program management in Windows, blogged about the changes Microsoft has made to Windows 8's boot process. The results are impressive - a boot time not much slower than waking from sleep on current Windows 7 and Mac OS X machines. This is, of course, a vital component of getting Windows NT ready for tablets.

They always promise this

Another new version of Windows, another new promise of faster boot up times. I thought you had used Windows long enough to notice the scam by now, Thom. ;)

Notice how they are improving the part of boot-up that is not really truly the problem with Windows. It is all the disk trashing that goes on when you log on along with their brain-dead FIFO I/O system that causes people to count boot-up times in minutes on budget computers.

Basically what is happening is that all disk access is serialized in the kernel without any regard to what process is doing the request. This means that if you have just a few background processes using the disk, the kernel buffers are filled with that and the 1 KB file the user is waiting for now takes 5 seconds to fetch.

Nothing they have announced here addresses the real problem (poorly designed I/O priority and that countless apps all start at the same time) and so the next version of Windows will effectively boot just as slow as the last one did on budget PCs.
