Ahead of next month's release of the Windows 10 October 2018 Update, Microsoft is warning users to make sure there's sufficient storage space for the upgrade, or there may be trouble.
The alert is targeted at users of systems with limited storage space, which may fail to initialize after running Windows Update.
Microsoft singles out "thin clients" and "embedded systems". But since Windows 10 demands around 10GB of space to install, it could be taken as a general warning for owners who've skimped on PC costs by buying Windows laptops with 32GB flash storage.
Many of these users have in the past been met with 'Windows needs more space' warnings during an upgrade.
The cause of this issue is something that users might assume Microsoft had eliminated by now, for example, by raising minimum storage requirements for hardware makers, which are respectively 16GB and 20GB for 32-bit and 64-bit Windows 10 desktops.
Until then, there's the now-deprecated Disk Cleanup tool. But owners of 32GB storage devices will probably have to follow Microsoft's manual instructions to make way for the next version of Windows 10.
Microsoft's Oct. 2 event in New York City is expected to feature more than just a couple refreshed Surface devices. Windows, Office, Cortana, and other software and services will likely get cameos, too.
