Do I need Microsoft RAC

Mark asked
Last Modified: 2017-04-09
In searching for RAC I've found that it is responsible for gathering reliability data and displaying it in chart view. It seems I can also disable RAC.

What exactly does it do and do I need it? I don't believe I've ever "displayed" this data in Chart (whatever that is).

Here is a full explanation on Microsoft RAC.


The RACAgent is a hidden scheduled task that is automatically configured during system installation. This task is responsible for gathering reliability data and displaying it in chart view.

If you do not want to track system stability, you can disable the RACAgent task by selecting the Disable option that is also available when you right-click on RacTask in the center pane.


Yes, I saw that page which is where I got that information for my OP.  However, that link simply says it's to "track system stability", and the various tabs on the Properties give me information about when the tracking task are run, finish and so on.

I still don't know what it's tracking, or where to find tracking results. That link does not tell me how to view the "system stability" information supposedly gathered by RAC. How do I do that?

Take a look at this link.


In Windows 7 Microsoft uncoupled the Reliability Monitor from the Performance Monitor; consequently the place to check the readings is via the Control Panel --> Action Center --> Maintenance, View reliability history.

So it looks like you would get to it from Performance Monitor in Windows 7.


In my Control Panel --> Action Center --> Maintenance, I have: Check your backup results; Check for solutions to problem reports; Backup; Check for updates; Troublehooting; System Maintenance -- no View reliability history.

In, Control Panel > All Control Panel Items > Action Center, there is a "View performance information" link, which gives me the "experience index."

Still, I don't know where to see these "system stability" metrics.

My question category is Windows 7.

Scott C:
I don't have a Win7 machine handy, but it looks like you can get to it through the Performance Monitor.
Hmmm, I thought the Performance Monitor was live-time, not historical. I'll try disabling the RACAgent and see if that has any effect on the Performance Monitor.
