Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify Print Spooler service is running
    Open Services console (services.msc) or run 'Get-Service Spooler' in PowerShell to check if the Print Spooler service is running
    Affected if The service is running - this is the vulnerable component that must be active for exploitation
  2. Identify Windows version and build number
    Run 'winver' from Run dialog, or run 'systeminfo | findstr /B /C:"OS Name" /C:"OS Version"' in Command Prompt, or use PowerShell '[System.Environment]::OSVersion.Version'
    Affected if The version displayed is within any of the affected Windows 10 or Windows 11 release ranges listed in the CVE
  3. Confirm exact build version for comparison
    Run 'winver' or check Settings > System > About to see the full Windows build number (e.g., 10.0.19045.xxxx)
    Affected if The build number is lower than the patched versions: 10240.21073 (1507), 14393.8246 (1607), 17763.7558 (1809), 19044.6093 (21h2), 19045.6093 (22h2), 22621.5624 (22h2), 22631.5624 (23h2), or 26100.4652 (24h2)
  4. Check installed security updates
    Open Settings > Windows Update > Update history, or run 'Get-HotFix | Sort-Object InstalledOn -Descending | Select-Object -First 10' in PowerShell to view recent patches
    Affected if No recent Print Spooler or Windows security update matching the CVE release date is installed

A user is affected if the Print Spooler service is running AND the Windows build number is lower than the patched versions listed for their specific Windows release.

  2. Open Settings > Update & Security > Windows Update
  3. Click 'Check for updates' to download and install all available updates
  4. Ensure the installed build number meets or exceeds the fixed version for your Windows release: Windows 10 1507: 10.0.10240.21073, Windows 10 1607: 10.0.14393.8246, Windows 10 1809: 10.0.17763.7558, Windows 10 21h2: 10.0.19044.6093, Windows 10 22h2: 10.0.19045.6093, Windows 11 22h2: 10.0.22621.5624, Windows 11 23h2: 10.0.22631.5624, Windows 11 24h2: 10.0.26100.4652
  5. Restart the computer after updates are installed
  6. Verify the update was applied by checking Windows Update history or running 'winver' again
