Issue: How to fix Windows update error 0x800704bd?

Hi, I have been trying to update Windows to the 22H2 version for all its new features, but I keep getting the 0x800704bd error every time I try. I've been waiting for several days, but the result is always the same. Please provide some advice.

Solved Answer

Windows updates are released on the second Tuesday of every month, as Windows started to be operated as a service. Updates to the operating system can include bug fixes, new usability improvements, UI[1] tweaks, and, most importantly – security patches for vulnerabilities,[2] which can ensure that the OS is resilient to cyberattacks.

Some users are unfortunate enough to experience error code 0xc1420121 when trying to update Windows 10 or 11, which doesn't allow them to enjoy new features and implement the mandatory security improvements.

Most people reported that the issue arises with the newest Windows version upgrade, 22H2, which was initially released on September 20, 2022, and promised a lot of new features and operating changes. Despite this, users can come across the 0xc1420121 error when dealing with any other update, for example, KB5019959.

In most cases, users notice that the patch has failed after a routine automatic update installation. Otherwise, users would be shown that their systems are lacking updates due to the 0xc1420121 error and that they should try again later. Unfortunately, trying once more – even several times – does little to resolve the situation as users return to square one.

Just like with any other update errors, this one could also be caused by numerous issues. Windows systems are dynamic and contain thousands of files, various apps, different settings, different versions of drivers,[3] and other components. Due to these parameters, the solution for a Windows update error can vary from computer to computer.

Below we provide several methods to fix the 0xc1420121 error, although we do recommend running a scan with ReimageMac Washing Machine X9 PC repair tool first – it might fix underlying issues automatically for you.

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.
