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 0x800f0845.0x800f0845 error

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.

Prevent websites, ISP, and other parties from tracking you

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.

A VPN is also crucial when it comes to user privacy. Online trackers such as cookies can not only be used by social media platforms and other websites but also your Internet Service Provider and the government. Even if you apply the most secure settings via your web browser, you can still be tracked via apps that you are connected to the internet. Besides, privacy-focused browsers like Tor is are not an optimal choice due to diminished connection speed.

Therefore, to stay completely anonymous and prevent the ISP and the government from spying on you, you should employ Private Internet Access VPN. It will allow you to connect to the internet while being completely anonymous, prevent trackers, ads, as well as malicious content. Most importantly, you will prevent the illegal surveillance activities that NSA and other governmental institutions are performing behind your back.


Recover your lost files quickly

Unforeseen circumstances can happen at any time while using the computer: it can turn off due to a power cut, a Blue Screen of Death (BSoD) can occur, or random Windows updates can decide to reboot the machine when you went away for a few minutes. As a result, your schoolwork, important documents, and other data might be lost.

Additionally, you might also be attacked by malware that can corrupt your Windows or encrypt files with a robust encryption algorithm, and ask for a ransom in Bitcoin for the decryption tool. Cybercriminals might not deliver what they promised, however, so it is better to attempt alternative file recovery methods that could help you to retrieve at least some portion of the lost data.

Data recovery software is one of the options that could help you recover your files. Once you delete a file, it does not vanish into thin air – it remains on your system as long as no new data is written on top of it. Data Recovery Pro is recovery software that searchers for working copies of deleted files within your hard drive. By using the tool, you can prevent loss of valuable documents, school work, personal pictures, and other crucial files.
