Look out: This browser link will crash your Windows 10 PC
Look out: This browser link volition crash your Windows 10 PC
UPDATE: Microsoft has patched this flaw with a organization update. Run across end of story.
Hot on the heels of final week's Windows x corrupt difficult drive problems comes another flaw that crashes a PC if you endeavor to open a specific link in some web browsers. And yes, this crash will yield that feared blueish screen of death (BSOD).
Both flaws were discovered past researcher Jonas Lykkegaard and detailed in his Twitter feed. This new bug doesn't open a web page, he said, but instead directs the browser to try to browse the PC'southward internal file organisation -- a feature mutual to most web browsers.

But considering the link is supposed to include an extra element, and the system doesn't seem to properly check for errors (perhaps because the control is coming from a web browser), Windows ten gets dislocated, trips over itself and pops up a BSOD.
Bleeping Figurer tried information technology on several systems using the Google Chrome browser and found that information technology works on Windows 10 version 1709 and later. Tom's Guide found that it besides works in the Brave web browser, which uses the same underpinnings as Chrome, and in an older version of the unrelated Firefox browser.
Use at your own adventure
Because this flaw doesn't seem to cause any lasting harm, it's probably safe to share the filepath: "\\.\globalroot\device\condrv\kernelconnect".
Play with this at your own run a risk. If you type information technology into the address bar of a browser, your reckoner will likely bluescreen and so practise the usual file checking. Our reckoner didn't restart automatically afterward that, so we had to power-wheel manually to make all well.
[Update: Our exam PC restarted normally a few times, merely is now stuck in an Automatic Repair boot loop. So, on second thought, you really shouldn't attempt this.]
[Update part 2: It now looks like the Automatic Repair boot loop may have been acquired past a completely dissimilar issue.]
Microsoft told Bleeping Calculator that it "has a customer commitment to investigate reported security issues and we will provide updates for impacted devices equally soon as possible."
Lykkegaard told Bleeping Reckoner that Windows 10 views the filepath every bit a command and expects the user to too blazon "attach" at the cease. But if the user doesn't add together annihilation, then Windows bluescreens.
He also said that whatever user, not just those with administrative privileges, can make this happen. Tom's Guide confirmed that was truthful.
This flaw tin be exploited. Lykkegaard found that especially crafted files downloaded from the internet could crusade PCs to crash when the files were opened, and Bleeping Computer said it had institute a way to make the PC crash upon startup.
Pranksters could also embed the filepath in harmless-looking links on web pages, emails, instant messages or social media. Simply none of these methods would be likely to cause permanent damage. [Or maybe it would -- see above.]
Update: Flaw patched
On Feb. nine, Microsoft patched this flaw as part of its regularly monthly software updates. Here'southward how to make sure yous install this patch.
