Windows 11 Pro Updates failing beginning with KB5077181

Question

Hello - I'm using Windows 11 Pro and am not able to successfully update beginning with Security Update KB5077181 on February 11, 2026. I sought online help a couple of weeks ago, but the update continues to fail. Would appreciate any help and/or advice to fix the problem, Thanks.

Answer 1

I would try the recovery option first. Go to Settings > System > Recovery > Fix problems using widows update, then select Reinstall now.

Answer 2

KB5077181 is the February 10, 2026 cumulative security update for Windows 11 versions 24H2 and 25H2. When this specific update repeatedly fails, the supported approaches in context are:

1. Install KB5077181 manually via Microsoft Update Catalog
   1. Go to the Microsoft Update Catalog entry for KB5077181.
   2. Download the MSU package that matches the system (for example, Windows11.0-KB5077181-x64.msu).
   3. Create a folder such as C:\Packages and copy the downloaded MSU file(s) into it.
2. Use DISM or PowerShell to install the package From an elevated command prompt (Run as administrator):
   • If installing directly on the running system:

          DISM /Online /Add-Package /PackagePath:C:\Packages\Windows11.0-KB5077181-x64.msu
     

     Or from elevated PowerShell:

          Add-WindowsPackage -Online -PackagePath "C:\Packages\Windows11.0-KB5077181-x64.msu"
     

   DISM will automatically detect and install any prerequisite MSU files in the same folder if required. Alternatively, use Windows Update Standalone Installer (WUSA) to install the MSU by double‑clicking it or running wusa.exe with the MSU path.
3. If multiple MSU files are required KB5077181 can come with prerequisite MSUs that must be installed in order. If using the individual‑file method, install them in the documented sequence, for example:
   1. windows11.0-kb5043080-x64_... .msu
   2. windows11.0-kb5077181-x64_... .msu
   Install each with DISM or WUSA before retrying Windows Update.
4. If update failures persist
   • Use the Feedback Hub app to report the update failure (include the exact error code from Windows Update history).
   • For additional interactive help, use the Get Help app in Windows or contact Microsoft Support.

These steps provide a clean, manual installation path that often resolves repeated Windows Update failures with a specific cumulative update like KB5077181.
