Here at my client, we've been noticing some extremely weird issues that have been slowing down the computers. Unfortunately there is no clear process as to what's slowing them down. Whatever has been downloaded, I believe it is affecting both the memory, and the page file usage. The one thing that I have noticed personally: 1) SVCHost.exe is the culprit affecting the memory. It is hogging the memory and not letting go, especially with the computers that only have 256mb of memory. Running tasklist /svc reveals that it's the SVCHost that contains all misc. processes, including Audio, as well as the Windows Update process. 2) I noticed on a few computers that were acting really slowly, the memory was increasing by 1/3 of a MB every second... so every 3 seconds another mb of memory would be in use and not let go. I watched SVCHost get up to 136mb of memory usage until I had to shut it down. This has been going on for about 2 weeks now.
