I’ve noticed a few subtle changes after updating to Windows 10 21H2. It’s primarily a security update, but I’ve found that systems with the update seem a bit more stable and responsive, especially on hardware with more recent CPUs. In terms of new features, it’s mostly under-the-hood improvements, so there won’t be significant visible changes to day-to-day productivity. However, I haven’t experienced any major bugs or issues. For a worry-free update, it’s always a good idea to back up your data first and ensure all your drivers are up to date.
