Task Manager Not Updating? Resume the Windows Refresh Speed

If Windows Task Manager CPU, memory, disk, or network data is frozen, change the real-time update speed from Paused to Normal in seconds.

Sometimes when you open Windows Task Manager, the data on the Processes or Performance tab appears frozen. CPU, memory, disk, or network values may stay unchanged for a long time. At first glance this can look like a system problem, but in reality running programs, network traffic, and resource usage are still changing normally.

In most cases, the system is not actually stuck. The more likely reason is that Task Manager’s refresh speed has been changed to Paused.

Quick Answer

Open Task Manager and change its update speed from Paused to Normal. On newer Windows 11 versions, open Settings in Task Manager and find Real time update speed. On older layouts, use View > Update speed. If the values still do not move, close and reopen Task Manager before investigating system-wide performance problems.

Symptoms

Common signs include:

  • CPU, memory, and other values on the Processes tab stop changing
  • Graphs on the Performance tab no longer update
  • Programs are clearly still running, but Task Manager looks frozen

Here is an example of what the issue looks like:

Example of Task Manager data not updating

Cause

Task Manager lets you adjust the Update speed, with options such as High, Normal, Low, or Paused.

If this setting is changed to Paused, the statistics shown in the interface stop refreshing. That is why CPU, memory, or network information can appear to be completely frozen.

As shown below, this option is usually available from the View menu in Task Manager:

Task Manager update speed set to Paused

Fix on Windows 11 and Older Task Manager Layouts

The setting appears in different places depending on the Task Manager version:

  • Newer Windows 11 layout: open Task Manager, select Settings at the lower left, and set Real time update speed to Normal.
  • Older layout: open View > Update speed and select Normal or High.

For the older layout shown in the screenshots, use these steps:

  1. Open Task Manager
  2. Click the View menu
  3. Find Update speed
  4. Check whether it is currently set to Paused
  5. Change it back to Normal or High

After that, watch the Processes or Performance tab again. In most cases, the data will start updating normally right away.

Changing this setting only affects how often Task Manager redraws its statistics. It does not pause running applications, CPU activity, network traffic, or Windows itself.

Additional notes

If the data still does not refresh after switching back to Normal, check a few other possibilities:

  • Whether you are using system-tuning tools or third-party performance monitoring software
  • Whether you are connected through a remote session and the interface is not refreshing correctly
  • Whether Task Manager itself is stuck, in which case you can close it and open it again
  • Whether only one graph is frozen while other values update, which may point to a driver or performance-counter problem instead of the refresh setting

That said, in most cases this issue is simply caused by Update speed being accidentally set to Paused, so checking that first is usually the fastest fix.
