Do cumulative updates include past fixes?

Hi folks,

I finally updated my desktop PC to Windows 11, and I was aware of a problem that Windows 11 had with AMD Ryzen processors that limited their ability to function at an optimal level. Microsoft fixed this with 2021-10 Cumulative Update for Windows 11 for x64-based Systems (KB5006746). However, I've looked into the update history and cannot find this update, but there is present 2022-03 Cumulative Update for Windows 11 for x64-based Systems (KB5011493) and 2022-04 Cumulative Update for Windows 11 for x64-based Systems (KB5012592). Would these updates cover the previous fixes?

Yea that is what cumulative means. MS only includes changes since the last update in the release notes.

"Most people are familiar with what is commonly referred to as Patch Tuesday or Update Tuesday. These updates are released on the second Tuesday of each month, and are known as the B release (where “B” refers to the second week in the month). B releases are typically published at 10:00 AM Pacific Time (PST/PDT).

Because they are cumulative, B releases include both new and previously released security fixes, along with non-security content introduced in the prior month’s Preview C release (see the next section). These updates help keep Windows devices secure and compliant by deploying stability fixes and addressing security vulnerabilities. B releases are mandatory."
