After the recent updates, Windows 10 users had a lot of problems.
It all started with the fact that back in January 2020, Microsoft reported a zero-day vulnerability in Internet Explorer, which attackers had already used for “limited targeted attacks.” The problem received the identifier CVE-2020-0674 and was associated with a vulnerability in the Firefox browser, which also became known in January. Apparently, the mentioned “limited attacks” were part of a larger hacker campaign, which also included attacks on users of Firefox. According to Microsoft, the vulnerability affects Internet Explorer 9, 10, and 11 when running on Windows 7, 8.1, 10, Server 2008, Server 2012, Server 2016, and Server 2019.
To protect users, Microsoft developers released a temporary patch that had a number of negative side effects for functions using jscript.dll. So, this fix caused printing failures on HP devices and other USB printers.
Then, as part of the February “Tuesday of updates,” a full-fledged KB4532693 was presented, but the problems did not end there. It turned out that some users lost data after installing update KB4532693 : their desktop and Start menu were reset to the default settings, and the files stored in the profile simply disappeared. It turned out that during the installation, user updates are switched to a temporary profile, and a backup copy of the original profile is saved with the extension .000 or .bak. But because of the bug, the restoration of the normal user profile does not end up, and sometimes the data is erased altogether.
Since Microsoft has not yet released new patches and a “patch for a patch”, specialists from Acros Security, a company developing a 0patch solution, entered the business. This platform is designed specifically for such situations, that is, fixes for 0-day and other unpatched vulnerabilities, to support products that are no longer supported by manufacturers, and so on.
Earlier, micropatch for CVE-2020-0674 was already included in 0patch , but it was not suitable for Windows 10 versions 1903 and 1909. Now Acros Security engineers said that they adapted their patch for all versions of Windows 10 and strongly advise users to use free version of your service, closing a dangerous problem, at least with the help of this unofficial fix.
