Windows Vista Explorer using 50% CPU all the time
I have task manager open and can see that Windows Explorer is using 50% cpu
all the time, this is not good. I have rebooted in safe mode and performed a
full virus scan using 2 anti virus programs. I have also scanned for spyware.
Explorer will crash on occasion and has to be restarted in task manager as a
new task under apps.

Re: Windows Vista Explorer using 50% CPU all the time

There could be some causes....

1: New Vista installs take time to adapt itself to your machine
(internal tuning) and usage habits (prefetch, cleanup...).

2. The folder/s you are opening require explorer to call an external
program to scan the file (metadata, indexing, video icon previews...)

It might be from an external program explorer is calling having
difficulty or related to interal stuff, do either of these sound like
the cause?
Check the Performance logs under computer management and see if it has
identify`d any root causes.

Re: Windows Vista Explorer using 50% CPU all the time
maybe you want to use ProceXP to check and see what other suspecious dll
files or exe files are executing with explorer.exe

i had similar problem on my comp as well, and i am using core 2 duo ... i
still do experience it abit, what i did was i close all the program also my
game... once the explorer finish running, the cpu usage came back down to 0
percent...

btw, i am using RC SP1 for Vista... and yes, it does has abit of that kind
of problem too... are you using SP1 ?
