How to Fix Error Code 0x80240020
-
Sign In as an Administrator
Do not attempt to run Windows Update from a guest account or a standard user account — it will fail and may cause additional errors. -
Open Windows Update Manually
-
Restart Your Computer and Try Again
Save all open documents and close all applications before restarting to avoid losing unsaved work. -
Run the Windows Update Troubleshooter
-
Clear the Windows Update Cache
Only delete the contents inside the Download folder, not the folder itself. Do not delete files from any other Windows system directory. -
Reset Windows Update Components via Command Prompt
Run Command Prompt as administrator only. Typing these commands incorrectly can affect system services. Double-check each command before pressing Enter. -
Disable VPN or Third-Party Security Software Temporarily
Only disable security software temporarily and on a trusted, secure network. Re-enable it as soon as the update is finished. -
Check for Windows Update via Microsoft Update Catalog
Only download updates from the official Microsoft Update Catalog website. Avoid third-party sites offering Windows update files.

When to Call a Professional
You should contact Microsoft Support or a qualified PC technician if: the error persists after completing all steps above; your PC is part of a corporate or managed IT environment where group policies control Windows Update (your IT department must handle this); Windows Update is completely non-functional or your operating system appears corrupted; or you are uncomfortable running Command Prompt commands. Microsoft's free support can be reached at support.microsoft.com.Frequently Asked Questions
What does Windows error code 0x80240020 mean?
Error 0x80240020 means Windows Update requires a logged-in, interactive user to proceed. It cannot complete the update silently in the background. You need to be signed in as an administrator and manually open Windows Update to allow the update to run.
Will error 0x80240020 go away on its own?
Usually not on its own. Since the error specifically requires user interaction, Windows is waiting for you to take action. Simply opening Settings > Windows Update while logged in as an administrator and clicking 'Check for updates' is often enough to resolve it immediately.
Can 0x80240020 be caused by a virus or malware?
Rarely, but malware can interfere with Windows Update services. If you have tried all the standard fixes and the error persists, run a full scan using Windows Defender (Start > Settings > Windows Security > Virus & threat protection > Quick scan or Full scan) to rule out malicious software.
Does this error affect all versions of Windows?
Yes, error 0x80240020 can appear on Windows 10 and Windows 11. The fix steps are essentially the same for both versions. The menu locations differ slightly — Windows 11 places update settings under Settings > Windows Update, while Windows 10 places them under Settings > Update & Security > Windows Update.
Why does 0x80240020 keep coming back after I fix it?
If this error keeps recurring, the most common causes are: a scheduled update task trying to run while no user is logged in, a corrupted Windows Update cache that keeps regenerating bad files, or a third-party security product repeatedly blocking the update service. Try clearing the update cache (Step 5) and checking whether your antivirus or VPN software is interfering (Step 7). For persistent cases, running the full component reset in Step 6 usually provides a lasting fix.
