Fix Windows Update and Activation Error Code 0x80072F8F 

If you are getting an error code 0x80072F8F while updating Windows or during its activation, you may try out the below workarounds and see if any resolve this issue. 

1] Disable Windows Firewall

Often it has been found that the Windows firewall prevents new updates from installing due to some internal glitches. It is thus recommended to disable Windows Firewall and check if you can now install pending updates on your computer. Here’s how to disable Firewall in Windows 11/10 –

  • Press “Windows key + R” to launch the Run dialog.
  • Type “firewall.cpl” and hit OK to launch firewall settings.
  • On the left pane, you may find a setting – “Turn Windows Defender Firewall on or off”. Well, click on it.

Windows Defender Firewall - Turn off

  • Tick the checkbox – “Turn off Windows Defender Firewall (not recommended)” under both Private as well as Public Network settings.
  • Click OK to confirm this setting. Don’t restart your PC as the Windows Firewall will then resume interfering with the update process. 

Now, check if you can install pending updates or activate your Windows copy.

2] Modify “Date & Time” to match your locale

In case your device date & time is not matching with the region where you reside, this may cause Windows updates to fail while installing. This might also result in activation issues on Windows 11 or 10 PC. So, go and check if your device date & time match the time zone where you live in. If you do find this mismatching, correct it by following the below steps –

  • Right-click on the Windows icon (Win + X), and select Run.
  • Type “timedate.cpl” and click OK.


  • Check if the time zone matches your regional area. If not, click on it and use the drop-down menu to select the appropriate time zone.
  • If changing the time zone doesn’t correct the date and time on your computer, click “Change date and time”, and manually set it to match your regional area. 

Modify Date & Time settings

  • Click Apply then OK to confirm the above changes and restart your PC.

regsvr32 softpub.dll /s
regsvr32 wintrust.dll /s
regsvr32 initpki.dll /s
regsvr32 mssip32.dll /s

  • After you re-register all the above files, come out of the Command Prompt and restart your PC. 

Sign back into your device again and check if the problem resolves. 

5] Configure the corrupted registry

There is a possibility that the registry itself has been corrupted somehow. In such cases, you need to manually configure the relevant registry entries. Here’s how to do this –

  • Press Win + R to launch the Run dialog.
  • Type “regedit” and hit OK. The UAC window will appear next, hit Yes to authorize opening it.
  • Inside the registry, use the left navigation to reach out to the below path –


  • Once you are there, look for the DWORD value named “MediaBootInstall”.
  • When found, right-click on it and select the option – Properties.
  • Change its value data field to “0“. Click OK to confirm the recent changes and close the registry window. 

Now that you have modified the registry, launch Command Prompt as administrator and do the following –

  • Copy/paste the below command and press Enter –

slmgr /rearm

  • When this code runs successfully, you will see a success message. 
  • Type “exit” to come out of the Command Prompt and restart your PC. 
  • Check if your Windows copy is activated now. 

6] Manually activate your Windows version

If for any reason, the activation issue is still there, manually activate your Windows version. Here’s how to do this –

  • Press Win + S, and type “slui.exe” in the text field.
  • Press Enter to visit System > Activation.
