Solutions

Solution 1: Enable the RACAgent Scheduled Task

2Navigate to: Task Scheduler Library → Microsoft → Windows → RAC
3Find "RacTask" in the right pane
4Right-click → Enable (if it shows Disabled)
5Right-click → Run to force an immediate data collection
6Wait 15-30 minutes, then check Reliability Monitor again
7If the RAC folder doesn't exist: the WMI repository may be corrupt (see solution 3)
8Also verify: Task Scheduler service is running in services.msc

Solution 2: Reset Reliability Monitor Data

1Open CMD as Administrator
2Stop the data collection: schtasks /change /tn "\Microsoft\Windows\RAC\RacTask" /disable
3Delete old reliability data:
4Navigate to C:\ProgramData\Microsoft\RAC and delete all contents inside
5Re-enable the task: schtasks /change /tn "\Microsoft\Windows\RAC\RacTask" /enable
6Force a run: schtasks /run /tn "\Microsoft\Windows\RAC\RacTask"
7Wait 15-30 minutes for new data collection
8Open Reliability Monitor: type "reliability" in Start menu search
9The graph should start populating with fresh data

Solution 3: Repair WMI Repository

1If the RAC task folder is missing, repair WMI:
2Open CMD as Administrator
3Test WMI consistency: winmgmt /verifyrepository
4If it reports inconsistent: winmgmt /salvagerepository
5If still broken: winmgmt /resetrepository
6Warning: resetrepository removes all custom WMI data — use as last resort
7After repair, restart the computer
8Run: sfc /scannow to repair any other system file damage
9Then: DISM /Online /Cleanup-Image /RestoreHealth
10Check Reliability Monitor after the next data collection cycle
