How to fix Starfield error 0xc000001d in Windows?

Issue: Hello. When I try to launch Starfield in Windows, I get the 0xc000001d error. Is there a way to fix this?

Solved Answer

The much-anticipated video game Starfield has been made available for Windows PCs. However, a unique fault, known as error code 0xc000001d, has been seen by some users, preventing them from correctly opening the game. Players who were ready to get into the game and have fun have experienced irritation and inconvenience as a result of this problem.

The error code 0xc000001d primarily arises due to the absence of the Advanced Vector Extensions (AVX) instruction set on the user's CPU, which is often a result of the CPU's AVX instructions not being enabled in the BIOS configuration. A collection of CPU instructions known as AVX is necessary for carrying out various complex tasks, including those needed by several modern video games like Starfield. The game has trouble operating when certain instructions are unavailable or disabled, which causes the error.

Users who have been eager to play Starfield may feel the effects of this problem pretty strongly. As the error message offers no insight into the underlying cause, it not only prevents them from fully enjoying the game but also has the potential to frustrate and perplex them. A lot of effort may be spent by gamers researching the issue, looking for fixes, or even attempting to update their hardware to fix it.

The AVX instructions must normally be enabled in the BIOS settings as a potential fix for this issue. But for some people, altering BIOS settings can be scary and might call for technical knowledge. Furthermore, some older CPUs may not have any AVX functionality at all, leaving customers with incompatible hardware. Users may need to think about hardware upgrades or other options in certain circumstances in order to enjoy the game.

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.
