14 DAY TRIAL // Microsoft has released a new set of cumulative updates for Windows 10, this time as part of the May 2021 Patch Tuesday cycle.
As always, all Windows 10 versions are getting such new updates, though worth knowing is that older releases are only serviced for the Enterprise and Education SKUs or if they’re running in LTSC.
The new cumulative updates are obviously focused on security fixes, and this month, Microsoft has addressed a total of 55 vulnerabilities with its Patch Tuesday cycle, out of which three are said to be zero-days that have already been exposed publicly.
The good news is that Microsoft isn’t aware of any attacks happening in the wild, but users are recommended to patch their devices as soon as possible anyway.
The three zero-day vulnerabilities are the following:
- CVE-2021-31204 - .NET and Visual Studio Elevation of Privilege Vulnerability
- CVE-2021-31207 - Microsoft Exchange Server Security Feature Bypass Vulnerability
- CVE-2021-31200 - Common Utilities Remote Code Execution Vulnerability
The new cumulative updates
The only two versions of Windows 10 that are no longer getting any updates are version 1703 and 1709, both of which have already reached the end of support for all SKUs.
