What is Windows10Upgrade folder in Windows? How to Delete it?

Windows10Upgrade

The Windows10Upgrade folder is created and used by the Windows Update Assistant program for downloading and installing the Windows Upgrade file(s). The Windows Upgrade file, which comes in the .esd format, is downloaded into this directory. After a successful download, the Windows Update Assistant program uses this ESD file to upgrade your computer to the latest version of Windows.

ESD (.esd) file – ESD stands for Electronic Software Distribution. Microsoft downloads the Windows upgrade files in the .esd file format. This file format provides a better compression than the older .wim (Windows Imaging Format) file format. The downloaded ESD files are used by Windows to install the latest update to the computer. The ESD files can be converted into the ISO format, and then be used to perform a clean install using a bootable USB/DVD.

Windows automatically deletes the .esd Upgrade file after the successful system upgrade. This folder only contains only a few megabytes of data afterwards. If Windows does not delete the .esd file automatically then you can delete it yourself either by using the Disk Cleanup utility or directly by using the Delete function in the Windows File Explorer.
