Tracked as CVE-2021-34484, the “zero-day” flaw enables hackers to breach all versions of Windows (including Windows 10, Windows 11, and Windows Server 2022) and take control of your computer.
Microsoft mistakenly thought it had patched the vulnerability (which was first found in August) when it was publicly disclosed in October. But the fix itself was found to be flawed, something the company admitted, and this drew even more attention to the vulnerability. Microsoft subsequently promised to “take appropriate action to keep customers protected” but two weeks later, a new fix has still not arrived.
Luckily the third-party security specialist 0patch has beaten Microsoft to the punch with a ‘micropatch that it has now made available for all Windows users “Micropatches for this vulnerability will be free until Microsoft has issued an official fix," 0patch confirmed.
You will need to register for a 0patch account and install its download agent before the fix can be applied, but with 0patch fast becoming a go-to destination for hot fixes which beat software companies to the punch this is a no brainer. Hopes will be high that Microsoft can release an effective patch sooner rather than later but, until then, all Windows users must act now if they want to be safe.

Interesting information has come out from Microsoft, Windows 11 dark theme will include a different sound theme from its standard light one.
When in dark mode on Windows 11, the system sounds generally become softer, and they echo a bit, creating a more soothing experience that matches the overall look and feel of the dark mode. Flipping back to light mode brings the system sounds back to their normal level.
However, even though the light model has slightly louder sounds than the dark mode, Microsoft has taken great care to make sure the audio is more soothing, according to a report from CNBC.
The designers of Windows 11 took inspiration from an approach called calm technology. Microsoft’s Christian Koehn and Diego Baca wrote about calm technology in a post on Medium. In it, they said, “Windows 11 facilitates this through foundational experiences that feel familiar, soften formerly intimidating UI, and increase emotional connection.”
According to a Microsoft spokesperson in a statement to CNBC, “The new sounds have a much rounder wavelength, making them softer so that they can still alert/notify you, but without being overwhelming.”
