Windows 10 is an operating system that is delivered as a service, which means that regular improvements, changes, security updates, and other features are shipped on a regular basis. Microsoft usually produces updates every second or sometimes fourth Tuesday of every month, hence the event is known as Patch Tuesday within the IT community.

Since Windows 10 release in 2015, 12 major OS upgrades have been delivered.[1] These usually include major changes for the UI elements and other improvements. Unfortunately, not all people can enjoy the new implementations due to a Windows update error 0x800f0984, as some reported on various IT forums.

The problem has been around for at least a few years, so it is not something new. In fact, Windows update errors like 0x800f0247 or 0x80070424 have been bothering users for years, as there is no universal solution that would work for everybody in most cases. There were also instances where the error occurred for everybody you tried to trigger the update process – 0x80070541 was fixed a few days later by Microsoft.

In any case, 0x800f0984 error can be seen after an attempt is made to update Windows – it can relate to feature, quality, or security updates. Several users reported that they were unable to upgrade the OS to the latest version, 21H1, due to this.
