Storage Space for Windows Updates
The apparent discrepancy of 15.4GB is not attributable solely to the applications listed under Installed Apps. Windows calculates application storage more broadly, encompassing large system components (such as Microsoft Edge, Microsoft Office, and OneNote), as well as hidden application data, caches, and supporting frameworks. These elements are included in the Installed Apps category even when their individual sizes are not displayed. To accurately identify and assess this hidden usage, it is advisable to utilize tools such as Apps & Features, Disk Cleanup, or Storage Sense, which provide a more comprehensive view of storage consumption beyond what is shown in the Settings interface.
