Windows 10 May 2022 cumulative update is now heading to consumers and enterprises with several bug fixes and general improvements. May 2022 Patch Tuesday doesn’t appear to be a big release as it comes with fewer consumer-centric improvements, especially when compared to the April 2022 Update.
Windows 10 May 2022 Update fixes as many as 75 vulnerabilities where eight are classified as ‘Critical’ given their critical nature (allows remote code execution or elevation of privileges). As per the release notes, Microsoft has fixed 21 Elevation of Privilege security issues, Feature Bypass Vulnerabilities, 26 Remote Code Execution bugs, and more.
In addition to the aforementioned issues, the company has also three zero-day bugs, including an issue related to the NTLM Relay Attack where an unauthenticated attacker could abuse the call method and use the LSARPC interface to authenticate to the attacker using NTLM.

- Open Windows Settings in Windows 10.
- Click on Updates & Security.
- Click on “Windows Update“.
- Select “Check for updates“.
- Click on “Restart now” to complete the installation.
Windows 10 is now on the backburner and all cumulative updates or even features are based on the version 2004 of the OS. For those unaware, all releases after version 2004 are actually based on this version of Windows 10 as Microsoft shifted its focus to the development of Windows 11 or Sun Valley.
Although the base is version 2004 for all later releases, the build revision number is still different for all versions. For example, if you’re on November 2021 Update, Microsoft says you will receive bUild 19044.1645. Likewise, if you’re still on May 2021 Update, you will be getting Build 19043.1645.
The build and version numbers are different, but bug fixes or the changelog itself are entirely identical. Windows 10 version 21H2, version 21H1, 20H2 and 2004 share the same code.
