Issue: How to fix Windows update error 0x800f0845 on Windows 10?
Hi. How can I fix Windows Update error 0x800f0845 when installing KB4056892? Thanks!
Solved Answer
Although the Error Code 0x800f0845 falls into the category of Windows 10 update errors, it’s not a regular one. It means that it cannot be fixed by resetting Windows Update components or restarting Windows update service.
The 0x800f0845 error mostly shows up when installing Windows 10 Cumulative Update KB4056892 (16299.192),[1] although it can also appear during the installation of other patches, such as KB4103721.[2] The former is an emergency update for AMD and Intel systems to immunize the Meltdown and Spectre vulnerabilities.[3]
Since the beginning of January, 2018 Microsoft, along with AMD, Intel, and ARM manufacturers, are working hard to fix the severe design flaw, which exposes a wide range of PCs, phones, tablets and servers to attack.
Actually, Windows 10 update KB4056892 is the one that should address the issue. The update has been released and pushed as one of the automatic Windows 10 updates.
Unfortunately, thousands of AMD systems encountered an endless boot loop once the system attempted to restart to finish up installing the KB4056892 update.[4] The others reported a BSOD error, which indicates the fact that the update failed to install with an error code 0x800f0845. 
The KB4056892 update bugs were reported to Microsoft, which reacted immediately[5] by scaling back the rollout of the Windows patches both for Windows 7 and 10.

By the way, Microsoft explained the reason why some of the AMD systems did not accept the KB4056892. Microsoft’s spokesman reported:
Some AMD chipsets do not conform to the documentation previously provided to Microsoft to develop the Windows operating system mitigations to protect against the chipset vulnerabilities known as Spectre and Meltdown.

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.
