Windows 10 May 2019 Update will require 32GB disk space

Windows 10 users with small main storage disks should take notice that the next big update will require a lot more disk space. Previously, Microsoft's minimum requirement for the 32-bit version of Windows 10 was 16GB, and 20GB for the 64-bit edition, but now that's been increased to 32GB for both versions.

As I already reported earlier this year, Windows 10 May 2019 Update will reserve 7GB of your storage capacity to prevent out-of-disk error issues with the installation of future updates. This disk space will be permanently blocked, but users will be able to manually reduce the amount of space reserved.

As ARS Technica reports, this may make it impossible to install the latest versions of Windows on systems with limited disk space:

If your system can't be upgraded, it'll be stuck with version 1809 for the remainder of its supported life; that's currently set to expire on May 12 2020 for Home, Pro, and Pro for Workstations editions, and May 11, 2021 for Enterprise and Education editions. Version 1809 also has a long-term servicing channel counterpart, which will receive bug fixes and security updates until January 9, 2024 and security fixes until January 9, 2029. It would be nice if Microsoft offered these fixes to hardware that's left abandoned by a feature update, but we wouldn't hold our breath.

The new disk requirement does not apply to Windows 10 IoT Edition.
