Windows 11 Task Manager Performance Panel is blank with no data
All data in the Performance tab of Task Manager is blank (CPU, Memory, Disk, etc. are not displayed). Restarting and resetting Task Manager does not resolve the issue. Please provide a fix.
This usually happens when Windows performance counters or WMI are broken. Task Manager itself is fine.
Try these quick fixes:
1. Rebuild performance counters (most common fix)
Open Command Prompt as Administrator and run:
lodctr /R
Reboot.
2. Restart WMI
- Open services.msc
- Restart Windows Management Instrumentation
3. Repair WMI if needed
winmgmt /salvagerepository
Reboot.
If the Performance tab is completely blank, it’s almost always corrupted counters or WMI — not a Task Manager bug.
