While using the active setup for Windows update installation on your computer, you may encounter an error stating that you do not have enough free disk space for installing updates. It may display that the installation requires only a small disk space, but after the installation starts, it demands for 3-4 times more disk space.
This error is very obvious. When you download a file, it gets downloaded in a compressed format and requires less space, but for uncompressing, it requires more space. So, when a file is uncompressed into a temporary folder, the .exe files install the theme and get removed from the hard disk. After the files are removed, only a small part of the disk space is used. The process completes itself during the installation.
