RMM Agent: Troubleshooting of persistent "All important and critical updates are installed; Reboot required" warning message

Situation

Warning message All important and critical updates are installed; Reboot required persists on RMM > Computers page despite of installation of the latest operating system updates and reboot of the machine. Updates status indicator is also active.

This situation may indicate incorrectly installed Windows update components.

Solution

In order to resolve this issue, consider safely renaming "SoftwareDistribution" and "Catroot2" system folders so that Windows updates could be re-downloaded and re-installed.

  1. Open elevated (i.e. launched under local administrator rights) Windows command line interface:

  2. Stop all Windows update-related services with the following four commands:

net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
  1. Rename "SoftwareDistribution" and "Catroot2" system folders to "SoftwareDistribution.old" and "Catroot2.old" system folders with the following two commands:
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 Catroot2.old

This way the initial folders will be preserved, just renamed, so that this action can be reversed if necessary.

  1. Restart Windows update-related services with the following four commands:
net start wuauserv
net start cryptSvc
net start bits
net start msiserver

  1. Close the command line interface and restart the machine.

  2. Windows updates will be re-applied and the initial issue with persistent warning message should disappear.
