On Settings > Storage, you can visualize how much each file type takes disk space in your PC, but if you click on Apps & Features, you might find that the disc space doesn’t add up with the one shown in Storage.
The reason the Apps & Features disc space doesn’t add up is that there are many files in the OS that cannot be accessed or viewed, and not all programs show a storage size in Apps & Features, an example is Google Chrome.
So, Apps & Features is not a reliable way to check the storage size taken up by apps. Since It does not show the storage size of many apps, some apps aren’t even listed.
Microsoft Edge is an example of an app without a storage size in Apps & Features:

In theory, you can also check app size in Control Panel, but you have the same shortcomings as Apps & Features. Some apps won’t show up.
So how do you check the exact disk space each app takes up?
How to Check How Much Disk Space your Programs Take
A better way to check how much disk space your apps take is located by using a third-party app called the Control Panel.
A better way to check how much disk space your installed programs take is by using a third-party app developed to manage your programs, such as IObit Uninstaller.
IObit Uninstaller shows the size of every app on your PC and allows you to sort apps by size or uninstall some apps that can’t be via Windows, like Microsoft Edge WebView2 Runtime.
- Download IObit Uninstaller and install it on your PC.
- With the program open, go to the All Programs tab to visualize all the programs installed on your PC:
- You can also go to the Windows Apps to visualize all Microsoft Store apps installed on your PC:
You can also use IObit Uninstaller to free up disk space by uninstalling multiple programs at once.
Conclusion
The Apps & Features disk space doesn’t add up, as not all programs are listed there. Also, due to hidden system files that can’t be accessed.
Since it doesn’t provide an accurate way to check how much storage size each app is taking up, you are better off using a third-party uninstaller to visualize all installed programs on your PC and uninstall them.
