How to fix
Windows Store Error Code:0x80073cf9
on Windows

I have been receiving error code 0x80073CF9 when trying to install apps on Windows Store. Not every application fails though, so I am very confused what triggers this error. That being said, I also have no clue how to fix it. Any help would be appreciated.

Windows Store,[ref en-1] also known as Microsoft Store, is the main source for users to download applications from.[ref en-2] While initially the store has been oriented towards the distribution of Universal Windows Platform apps, now it contains over 669,000 applications for Windows, Phone, and universal apps. People can find both free and paid apps with various price tags.

Since third-party sources are often accused of spreading malware[ref en-4] and scams[ref en-3], people tend to rely on sources like Windows Store because they use filters and collaborate with trusted developers. Unfortunately, but Windows Store errors are very common, which is why apps on it become unavailable temporarily - 0x80073cf9 error is one of them.

Windows Store errors are overall very common - 0x803fb005, 0x80244018, 0x8024001E or 0x87AF000B are just a few examples. Each of these codes might indicate different reasons for their appearance, although they all result in users' inability to download and update apps from the Store. Without a doubt, it can be an extremely frustrating experience. Luckily, there are several ways you can fix 0x80073cf9, as long as you follow the free instructions we provide below.

Most users who encountered the error said that the problem is not universal, as some users might face it when downloading some apps, while others claim they can't use the Store at all due to error code 0x80073cf9.

Installation Failure: Windows failed to install the following update with error 0x80073cf9: Gears of War.

While the error code is most commonly encountered while attempting to download apps from Windows Store, others might face it when updating Windows.
