How to get this update
Microsoft bundles the latest servicing stack update (SSU) for your OS together with the latest cumulative update (LCU) in a single package. The SSU for this release is KB5063707, producing versions 22621.5619 and 22631.5619.
This update is available through the following channels:
- Windows Update and Microsoft Update - the update downloads and installs automatically.
- Windows Update for Business - the update downloads and installs automatically according to your configured policies.
- Microsoft Update Catalog - download the standalone package directly from the catalog.
- Windows Server Update Services (WSUS) - the update syncs automatically when Products is set to Windows 11 and Classification is set to Security Updates.
To remove the LCU after installation, use the DISM /online /remove-package command with the LCU package name as the argument. You can find the package name by running DISM /online /get-packages. Running wusa.exe with the /uninstall switch will not work on the combined package because it contains the SSU, and the SSU cannot be removed once installed.
Frequently asked questions
Does this update apply to both Windows 11 22H2 and 23H2?
Yes. KB5062552 covers Windows 11 version 22H2 Enterprise and Education editions as well as Windows 11 version 23H2 in all editions. Both editions receive the same resulting build numbers - 22621.5624 for 22H2 and 22631.5624 for 23H2 - after installation.
What is the end-of-servicing timeline for Windows 11 version 22H2?
As of June 26, 2025, Windows 11 version 22H2 Enterprise and Education editions no longer receive non-security preview updates. Monthly security updates continue until October 14, 2025, after which the version reaches end of servicing entirely. Microsoft recommends upgrading to the latest version of Windows 11 to remain protected.
What should I know about Secure Boot certificate expiration?
Secure Boot certificates used by most Windows devices are set to expire starting in June 2026. Microsoft has been deploying updated certificates to consumer and non-managed business devices over recent months. Devices that have not yet received the newer certificates will continue to start and operate normally, and standard Windows updates will continue to install. IT administrators should consult the Secure Boot Playbook for Windows clients and Windows Server.
Will this update also install Microsoft Store application updates?
No. Windows updates do not install Microsoft Store application updates. Enterprise users should refer to Microsoft Store apps - Configuration Manager guidance, while consumer users should use the Get updates for apps and games in Microsoft Store option to keep Store applications current.
