Re: Windows Update & System restore

Hi- I received the automatic update KB900485 on 4/26/06. My machine is
now using 400m of PF even when nothing other than the OS is running. I
restored my system to the restore pt just prior to the automatic
update, but the machine is still running slow and the "check update
history" on the windows update page still lists the update. The update
is not listed under add remove programs with other older updates. Is
there a way to figure out why it isn't being removed? Go back to an
even older restor pt? Also, there is a new "Windows Security" yellow
padlock icon displayed when you open the Start menu. Same update I
believe. Anyone have any thoughts? Hopefully? Thanks, Victoria

Most if not all of that PF Usage reported by Task Manager will be
"phantom usage" relating to the unused portions of memory allocation
requests.

By design Windows must allocate memory address space to satisfy all of
the memory allocation requests that are issued by Windows components,
device drivers, application programs, etc. And these allocation
requests are almost always for larger amounts of memory than are
actually needed under normal circumstances. So what Windows does is
to allocate RAM only to those portiosn of the requests that are
actually used, and to map the unused portions to locations in the page
file. Note that this mapping of unused memory requests to the page
file does not require any disk activity. All that is needed is to
make entries in the memory mapping tables maintained by the CPU.

The PF Usage reported by Windows Task Manager on the performance tab
includes these unused requests in the total.

If you are concerned about your computer's apparent slow performance
launch Task Manage and go to the Processes tab. Click twice on the
CPU column header to sort the list into descending order based on CPU
usage. That will show you what is using the most CPU time, which
might help identify the culprit.

Good luck
