If an update fails, you can usually restore the previous version of an application. Updates are often downloaded and installed in the background. One reason for this is that the Windows operating system requires a significant amount of disk space to update and maintain system files. Your free disk space gradually shrinks in a seemingly inexplicable way. But things usually look different after you've used the computer for several months and installed various space-intensive applications. As a user, you might wonder if you’ll ever need those 500 gigabytes or 1 terabyte of space.
When you purchase a new computer or reinstall your operating system, it often seems to have infinite amounts of disk space.
