Hello!
Explorer.exe began to use much of CPU (it look like) after increasing RAM
from 2GB to 6GB. Explorer.exe uses much of CPU when I open a 4Gb mkv file in
VLC player when uTorrent has been seeding for 8 hours already.
OS is Windows Vista Ultimate SP2 x64. Page file is 'system managed' on G: HDD.
Before increasing RAM, HDD was busy for several minutes in 30 minutes
intervals when uTorrent has been seeding.
How to prevent the explorer.exe from overloading CPU?
ProcessExplorer64.exe
http://download.sysinternals.com/Files/ProcessExplorer.zip gives the
following for explorer.exe when the later uses much of CPU:
