KB5077181 after this KB update users who have laptop of 23H2 facing network issues what is the fix

Answer 1

1

If version 23H2 is installed on the device(s), that is a very old version of Windows, and no longer supported, is the 24H2 or 25H2 version not available on the updates section in the settings app.

2

What network problems are the users experiencing after installing that update, also KB5077181 is the January update, are the users not offered the March update.

Answer 2

KB5077181 is a cumulative update that must be installed using the correct package order when applied manually. Network-related issues (for example, Wi‑Fi or Bluetooth problems) after installing a cumulative update are often resolved by fully power-cycling the device hardware, not just doing a normal restart.

For Windows 11 23H2 devices that started having network issues after KB5077181:

1. Fully power-cycle the device
   • Shut down Windows completely.
   • If it is a laptop with a removable power source (or a desktop):
     • Turn the device off.
     • Disconnect the power supply (and battery if removable) or turn off the PSU.
     • Wait several minutes.
     • Reconnect power and start the device again.
   • This type of full power reset has been reported to restore Bluetooth and Wi‑Fi functionality after recent cumulative updates.
2. Reinstall KB5077181 correctly if it was applied manually
   • If KB5077181 was installed using standalone packages, ensure all MSU files for this KB are downloaded to the same folder and installed together using DISM or Add‑WindowsPackage so that all prerequisites are correctly applied:
     • Example (elevated Command Prompt on a running PC):
       • DISM /Online /Add-Package /PackagePath:c:\packages\Windows11.0-KB5077181-x64.msu
   • Alternatively, install each MSU file individually in the documented order if using Method 2.
3. If issues persist
   • Use Windows Update (not just Catalog MSUs) to reinstall or repair the current Windows version as documented, which can fix update-related corruption while keeping files and apps.

If the problem continues after a full power-cycle and a correct reinstall of KB5077181, reinstalling the current version of Windows via the supported repair/reinstall path is the next step.
