Boot Performance Issues

I have noticed over the last two months some slow boot times. I have turned off some of the unnecassary startup programs and noticed a lot of errors in the event log. I was wondering if anyone could help me understand what the mean.

Here is a couple of the log reports

Here is the critical error one

And the most recent one:

This application took longer than usual to start up, resulting in a performance degradation in the system startup process:
File Name : dwm.exe

When I did the first install everything was booting up quickly. I am hoping that when I get the retail version and reinstall everything will be back to normal and fast. I am just concerned this is a hardware issue. I dont like the term, "Boot Degradation"...

Have you tried clearing your prefetch..?


Remember that once you have cleared it the next boot will take twice as long, but once it has re-learnt its drivers and cached them each boot after that will be much faster..

I forgot about that. I cleared the prefetch and the first two boots were quite slow but this last boot was much faster. Hopefully this will remain the same.

Thanks for the reminder

For those that are here researching because you have a similiar problem - do NOT clear your prefetch. Prefetch is a program that tracks and keeps the order of programs and services in your boot time - unless you change that order or take out programs/services at startup or even add them in.

If you clear Prefetch then you're starting all over again so it acutally SLOWS DOWN your startup. DO NOT CLEAR PREFETCH to speed up your boot time!
