Issue: How to fix Windows update error 0x800703e3?

Hello. I have recently noticed that my Windows update keeps failing with error 0x800703e3. It shows that some cumulative and driver updates are failing while others are installing. Is there something that could be done about this?

Solved Answer

Microsoft operates Windows OS as a service, which means that users can expect to receive constant updates. One might receive several different types of updates, including cumulative, security, bug[1] fixes, and others. Most of these are shipped every second Tuesday[2] of every month, which makes the pattern more predictable.

Unfortunately, not all updates reach users successfully, and error 0x800703e3 is one such example – it doesn't matter if the update is initiated manually or automatically, it keeps failing every time with the same code. This is not something uncommon, as we have already covered similar problems users had to deal with – 0x800704f1, 0x800700a1, or 0x80246013, to name a few.

Windows update errors such as 0x800703e3 can occur due to various reasons, including corrupted system files, damaged update components, general bugs, or other problems. In this case, most users found it difficult to install cumulative updates along with graphic driver updates.

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.
