I have a laptop with Windows 10, and since November I have not been able to install any cumulative updates. The most recent version is '2021-12 Cumulative Update for Windows 10 Version 20H2 for x64-based Systems (KB5008212)'. Meanwhile, security intelligence updates have installed successfully.
Every time I attempt to perform the update, it downloads the update, but the install halts at 20%. After half an hour, I get the error message 0x80073701.
I have attempted every solution I could find to resolve the situation, including running the troubleshooter, running the system file checker or DISM tool, emptying the system distribution folder, and resetting windows update. Nothing has been able to fix the issue.
I would very much appreciate your suggestions.
