Disable Performance Counters Running in Background
There is a performance monitor located in XP in Control Panel > Administrative Tools > Performance that does not usually see the light of day with most users. What it does is track a number of different areas regarding your system’s performance, such as CPU activity and hard drive access. It runs constantly in the background using up system resources without most people even using it. If you have no use for this and wish to reclaim some system resources, there is a tweak to turn it off.
First, you will need to download and install the Extensible Performance Counter List Utility. Go to C:Program FilesResource Kit and run the Exctrlst.exe utility.
Select each line in the “Extensible performance counters” window and clear the “performance counters enabled” button below. This must be done for each counter. When it’s finished, just exit the utility.
The next time you access the performance monitor, there will be no information available or shown.
Disable Remote Registry
This service allows your registry to be edited from a remote computer. It is most likely the case that this service is not needed, not to mention a possible security risk for people concerned about their system security.
To turn it off, go to Start > Run and type services.msc. Set the startup type to “Manual” or “Disabled” for XP’s “Remote Registry” or 2000’s “Remote Registry Service”.
If you do not plan on using XP’s fancy blue, olive green or silver themes and aren’t running any skinning utilities that rely on XP’s theme service, then turning it off altogether and running Windows Classic Style would free up a fairly significant amount of memory. To use Windows Classic Style, simply right click on the desktop and click “Properties. Go to the “Appearance” tab and change the “Windows and Buttons” drop down menu to “Windows Classic Style”. Hit Apply and OK.
To shut off the service entirely, go to Start > Run and type services.msc. Double click on “Themes”. On the “General” tab, set the startup type to “Manual” or “Disabled” and click OK.
