You have a service or two that has a modest memory leak and you would want to restart right when it has consumed a certain amount of memory.
This approach has an advantage over scheduled restarts because it will restart the service right when it is needed, or otherwise it leaves "it" alone.
This requires the use of Microsoft PowerShell which is available for XP (as download) and built-in on Windows Vista/7 and Server 2003 or later.
First time you try to run it, it is very likely that it won't run the script locally because out of the box, the script file is disabled. You will need to manually type in after manually opening PowerShell
Set-ExecutionPolicy RemoteSigned
From that point on it should permit running.
#
# This script detects the memory usage threshold and then restarts a service named in this script. You can
# run this script periodically in Scheduled Task to restart memory leaking service.
#
# Remember to do
# Set-ExecutionPolicy RemoteSigned
# so that this script can run
# To run this script from a BAT,
# powershell -File RestartService.ps1
#
# First comment out the following two lines so that you can get the basic idea of the content of this stuff by
# looking at the proc.txt output file in your editor to hunt for the process name etc.
# Then it's easier to figure out the filtering for the name and the threshold.
#
#$Processes = Get-WmiObject -ComputerName "localhost" -Class Win32_PerfFormattedData_PerfProc_Process
