How to fix Microsoft Store error 0x80070426?

Issue: Hi. My computer works fine, but recently, I've been getting a 0x80070426 error in the Microsoft Store, which prevents me from using it (I can't update or install new apps). Any idea what's going on?

Solved Answer

One essential part of the Windows operating system is the Microsoft Store, which serves as a central destination for downloading and updating a vast array of applications. However, like any complex software system, it is not immune to issues. The Microsoft Store error code 0x80070426 is one problem that users may encounter – it significantly reduces the operation of the Microsoft Store, making it impossible to update or download new apps.

The 0x80070426 error might have several causes. It is frequently linked to issues with the Microsoft Store itself, including bugs in the program or problems arising from faulty app files and caches. These issues may interfere with the store's regular operations, which could result in an error.

User account files that have been corrupted could potentially be a factor. In order to offer individualized services, the Microsoft Store depends on user account information; therefore, any errors or damage in these files may hinder the store's ability to operate.

Recognizing that this problem's potential solutions vary based on its underlying cause is crucial. If internal Microsoft Store issues or corrupted files are the cause of the issue, resetting the application or clearing the cache can be helpful. But, you might need to consider creating a new user profile or correcting an existing one if the problem is connected to a corrupted user account.

In more serious cases if these solutions don't work to resolve the 0x80070426 error, reinstalling Windows with the Media Creation Tool can be a viable option. By updating the operating system using this way, you can fix any underlying issues that may be generating the error without deleting your files.

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.
