I got 1 min. from hitting the restart button back to usable desktop. 33 sec. from hitting power button to usable desktop. 5 sec. less if unplug my camera, but I used more than just bootvis to get it. Used to make seven to eight passes of the line on the boot screen. Now it's 1 without Cam and 2 to 3 with Cam plugged in. The following is how I got mine------------------------------------Use BootVis optimization tool to optimize computer boot speed. Reboot and see if boot has improved. Go to prefetch and either delete all files or delete NTOBOOT file. Go to regedit.
(prefetch will start prefetching fresh copies on reboot)
HKEY_LOCAL_MACHINE/system/current controlset/Control/SessionManager/Memory Management/PrefetchParameters
Click on EnablePrefetcher and change the value from (3) to (1). Now close regedit and reboot.
This will still allow prefetching, but not the NTOBOOT file which is apparently XP's own boot trace prefetch file. This seems to allow holding of the BOOTVIS Optimization without trying to overide it with XP's boot tracing and optimization.
This fix is experimental, but has worked great for me. I noticed when you would use BootVis you would get one fast reboot then it would slow down. After using the above it holds the fast boot
always.( WARNING: This may not be reversible except by system restore. Make sure you create a good restore point if you don't want to chance it.)
