What to do now

  1. Check whether you run Windows Remote Desktop Services (RDP) and identify your exact Windows version and build number (e.g., “Windows 10” or “Windows Server 2019” plus the build).
  2. Compare your build to the fixed versions below; if you are on an affected build, plan an immediate update to a fixed build.
  3. Apply the available Windows updates that move you to at least the fixed build for your exact product/branch:
    • Windows 10: update to 10.0.14393.9512, or 10.0.17763.9245, or 10.0.19044.7725, or 10.0.19045.7725
    • Windows 11: update to 10.0.22631.7582, or 10.0.26100.9445, or 10.0.26200.9445, or 10.0.28000.2954
    • Windows Server 2012: update to 6.2.9200.26349
    • Windows Server 2012 R2: update to 6.3.9600.23397
    • Windows Server 2016: update to 10.0.14393.9512
  4. After updating, confirm the build number changed and that Remote Desktop Services continues to run as expected; then re-test any remote-access workflows you rely on.
