Hello Rajesh,
The error code 0x80240031 is a Windows Update failure that usually indicates corruption in the update cache or a problem with the servicing stack. It’s not tied to a single KB, but rather to the update mechanism itself. The most reliable way to address it is to reset the Windows Update components and ensure the servicing stack is intact.
Start by opening an elevated Command Prompt and running:
net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 catroot2.old
net start wuauserv
net start cryptSvc
net start bits
net start msiserver
This clears the update cache. After that, run sfc /scannow and then DISM /Online /Cleanup-Image /RestoreHealth to repair any corruption in system files or the component store.
If the error persists, check that the latest Servicing Stack Update (SSU) is installed. Microsoft often releases SSUs separately, and without them cumulative updates can fail. You can manually download the SSU for your build from the Microsoft Update Catalog (catalog.update.microsoft.com in Bing).
Finally, confirm that Group Policy or third‑party security software isn’t blocking updates. In some enterprise builds, policies under Computer Configuration → Administrative Templates → Windows Components → Windows Update can prevent installation.
If none of these steps resolve the issue, it’s likely a known regression in the current build. In that case, the only option is to wait for Microsoft to release a fixed cumulative update or SSU.
I hope you've found something useful here. If it helps you get more insight into the issue, it's appreciated to accept the answer. Should you have more questions, feel free to leave a message. Have a nice day!
Harry.
