If you recently installed the Windows 10 November 2019 Update, then you've probably noticed that the available space has shrunk several gigabytes. However, it's not because the update takes more space. Instead, it's because, the system creates a copy of the previous installation as a precaution, in case the device needs to rollback to its original settings as a result of errors or compatibility problems during and after the upgrade process.

Although this is a useful mechanism, Windows 10 will still keep the files inside the "Windows.old" folder taking up a lot of space, even when the upgrade completed successfully. Getting rid of these files allows you to reclaim roughly around 8GB to 12GB of storage, which it may not be significant on devices with multi-terabyte drives, but on laptops with limited storage could mean more time without thinking to upgrade the internals.

Of course, this only applies for devices upgrading from the October 2018 Update (version 1809) or older releases, as computers running the May 2019 Update will receive version 1909 as a monthly cumulative update, which doesn't require reinstallation. Therefore, the install won't take much space, and no security copy will be created. (Though, you'll be still able to undo the update like with any quality update.)

In this Windows 10 guide, we'll walk you through the steps to delete the leftover files wasting valuable space after upgrading to version 1909 using the Settings app as well as with the legacy Disk Cleanup tool.
