Issue: How to Fix Windows 10 Update Error 0x800736B3?
I cannot install any updates on my Windows 10 Enterprise. The installation returns error code 0x800736B3. Could you please help?
Solved Answer
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 Outdated Windows OS is more vulnerable, sluggish, lacks of improvements, and may return various errors.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.

If you don't want to struggle with manual repair techniques, please use the automatic software. All recommended products have been tested and approved by our professionals. Tools that you can use to fix your error are listed bellow:
Access geo-restricted video content with a VPN
Private Internet Access is a VPN that can prevent your Internet Service Provider, the government, and third-parties from tracking your online and allow you to stay completely anonymous. The software provides dedicated servers for torrenting and streaming, ensuring optimal performance and not slowing you down. You can also bypass geo-restrictions and view such services as Netflix, BBC, Disney+, and other popular streaming services without limitations, regardless of where you are.
Don’t pay ransomware authors – use alternative data recovery options
Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files – Data Recovery Pro.
