How can I fix code 31 in Windows 11?
I’m experiencing an issue with my Windows 11 computer where I keep encountering a “Code 31” error. It seems to be related to my device manager and the drivers for one of my hardware components. Every time I try to update or reinstall the drivers, the error persists. This problem is preventing me from using certain hardware functionalities properly, and I’m not sure what else to try. I’m looking for a detailed explanation of the common causes behind this error and why it occurs. Additionally, I’m interested in understanding any preliminary checks or diagnostic steps I should take before attempting to fix the problem. Your guidance on this would be greatly appreciated as I’m at a bit of a loss here.
