Don’t do it. Most people aren’t going to experiment with navigating to root Windows 10 folders, but just in case anyone might be digging around in the software guts of their PC, it’s best to stay away from inputting this file path into your browser: “xxxxxxxxxxxx\device\condrv\kernelconnect”. [I'm not inserting the code in this thread.] It will not only instantly crash your PC, but also give you the dreaded blue screen of death (BSOD), from which your PC might not be able to recover. Do not do it!
According to Tom’s Guide, the bug was recently discovered by Windows security researcher Jonas Lykkegaard, who’s been tweeting about the issue on-and-off since October 2020. Lykkegaard explained that when the above path is opened in Windows 10, regardless of if the user has administrative privileges or not, the system can’t properly check for errors when it tries to connect to the path, resulting in a BSOD crash.
Aside from developers, there isn’t much of a reason why an average Windows 10 user would want to dig around in the root folders, especially at the kernel level; the Windows kernel is a crucial program that allows the operating system to function, controlling everyday processes like running drivers, and starting and ending programs. . . .While Gizmodo hasn’t tested the link ourselves (out of an abundance of caution that it might kill one of our few test PCs), both Tom’s Guide and BleepingComputer have sacrificed a PC for the cause. The PC that Tom’s Guide used became stuck in an Automatic Repair boot loop. BleepingComputer didn’t say if its PC made it out alive, but it confirmed this bug is present on Windows 10 version 1709 and later.
The rest is at the link.
I've used both Tom's Guide and Bleeping Computer when solving computing and software issues. Bleeping Computer in particular has a lot of answers, but search before you ask a question.
