Microsoft's tenacity in imposing AI across its product stack has cornered Windows into a tough spot. Mac and Linux are catching up in terms of software compatibility, and Windows' longstanding flaws have begun to outweigh its universality. Even though the company has promised to fix the OS and has initiated a course correction, the mistakes just keep slipping through the cracks. The latest in the line of discrepancies is a new Windows update that, funnily enough, won't install for a lot of users.
Microsoft pushed the KB5079391 non-security update on March 26, 2026, featuring "production-quality" improvements, which means it's part of the efforts to make the OS more stable/reliable. It's ironic then that the update refuses to install, throwing up the 0x80073712 error code in a loop. This code means something is broken or missing in the update files, which is preventing Windows from piecing together the update.
