I cannot install any updates on my Windows 10 Enterprise. The installation returns error code 0x800736B3. Could you please help?

Are you installing Windows Updates regularly? Hopefully, the answer is yes. Outdated Windows OS is more vulnerable, sluggish, lacks of improvements, and may return various errors. Sadly, the latest Windows version, Windows 10, can’t be updated because the download and install of the updates end up with various error messages, for example, Error Code 0x800736B3.

Like most of the Windows Update errors, usually the 0x800736B3 error shows up due to the failure of Windows Update service. Nevertheless, the system may also return this bug due to the missing or corrupted .Net Framework. The only way to isolate the culprit is to try diverse error 0x800736B3 fixes, so we’ll provide a couple of applicable fixes. Before you perform the fixes, try to reboot your PC, check the system for malware, and run a scan with a professional optimization utility, such as [d1].
