Windows 10: Under Settings & Features what does an unavailable app mean? Solved

    Under Settings & Features what does an unavailable app mean?

    I see a long list of my windows 7 apps. Some have a size and date and other have the date and the words "unavailable".

    What does this mean and if it means I can't run the app, what can I do about it? Do I have to find a Win 10 compatible version?

    Thank you,

    The Apps & Features list shows the applications you have installed on your system, both Windows Store app and desktop applications. By default the list is sorted by the size they occupy on the hard drive.

    List also shows the date the app was last used:

    In case of a Windows Store app showing size as Unavailable, it only means that you have not yet used that app since you upgraded to 10 like Mail and Calendar, Maps and Microsoft Solitaire in the below screenshot; as soon as I will use them, the Settings app can calculate their size. In case of a desktop applications Unavailable is also sometimes shown even when you have used the application but for one or another reason the Settings app cannot determine the size of the application. In screenshot below you can see Maxthon Browser, Microsoft Expression Encoder and Office 365 size as Unavailable although I use all of them on daily basis:

    Short answer: Unavailable in this list simply means that the size the application is taking on your hard disk cannot be determined by the Settings app.

    Thank you very much for your answer. I was getting a little confused, because once I found an entry, I went to the apps and attempted to run it. Some started fine and others looked liked they were loading, but nothing happened. So the unavailable did not make sense. Now I understand that it is only a size field I can ignore them and work on the apps that do not appear to be starting.
