How to remove data encryption for Universal Windows Platform apps

Question

*This text has been translated from Simplified Chinese.

This device initially has device encryption and Bitlocker enabled. Later I turned them off, but UWP Apps' data files are still encrypted. I've tried unencrypting the property, but I get "Unable to apply property, the parameter is incorrect". Then open the "decrypted" file with any app will show "The APPX file cannot be accessed because it is not encrypted as expected." I cannot copy or compress the file without unencrypting it. How do I remove this unbelievable setting?

Answer 1

This is an intentional action taken by Microsoft.

If you install UWP apps to a drive other than the system drive (usually C:), Microsoft will encrypt the files in a way that only the system and the app itself can access. Users cannot access directly or decrypt them.

And worse, if you try to create or modify other files using this program it may get encrypted just like the program files themselves as well.

The only solution is to move the UWP app back to the system drive (C:).

这是微软特意这么做的。

如果你安装UWP应用到非系统盘（通常是C盘），微软会以一种只能系统和应用本身解密的方式加密程序文件。用户不能直接打开或解密他们。

更糟的是，用此UWP程序创建或修改过的的任何文件也可能会跟这些程序文件一样加密。
唯一的解决方案是迁移UWP应用回到系统盘（C盘）。
