Windows 10, initially promised as “the last version of Windows,” was released back in 2015. It was subsequently succeeded by Windows 11 several years later, and now mainstream support is set to end in October 2025. Microsoft has mostly just released bug fixes and minor app updates for Windows 10 over the past few years, but now an improvement for update packaging is rolling out.
Microsoft is bringing a significant under-the-hood improvement introduced in Windows 11 to Windows 10 PCs: decreasing the size of update downloads. Windows 11’s updates are notably more efficient due to optimized packaging, including the elimination of reverse differentials from cumulative update packages. Now, this optimization is being extended to Windows 10, version 22H2, with the release of the April 23, 2024 (KB5036979) update. Starting from this update, you can expect a significant reduction in update package size, from approximately 830 MB to around 650 MB, facilitating smoother updates and conserving network bandwidth. This applies for both the current update and any updates that might land on your PC in the future.
