Windows Update Slimming: Less Disk Space on Windows 11 24H2

Microsoft says Windows Update will soon use significantly less local disk space — and for the millions of people running small SSDs or entry-level laptops, that's one of those changes that quietly fixes a real, everyday pain point.

Background / Overview​

For years, Windows updates have behaved like cautious packrats: they download entire update packages or large temporary payloads, keep copies for rollback, and hold reserved storage to guarantee the next update can be applied. That behavior improves reliability but often costs users several gigabytes of usable storage — a serious problem on modern 64GB and 128GB devices. Microsoft has been working to reshape that plumbing with a set of servicing and delivery changes that collectively shrink download sizes, reduce temporary storage needs during installation, and clean up leftover files more aggressively. Some of these changes trace back to the Unified Update Platform (UUP) architecture introduced a decade ago; others are new servicing innovations rolled into Windows 11, version 24H2 and the servicing pipeline that follows it. m](]) This article breaks down what Mi...m/"]Windows Update Will Soon Use Less Storage
