Um, you can put a file, registry.dat into your application bundle. It's a registry hive. It's found by searching for HKLM\Software. Writes to it won't persist between application launches. If you put file paths into it, you can use the same aliases from App-V.
You should be able to write to HKCU, and it should persist between launches. But, access to this is virtualized, and you are not accessing the real thing. Don't think you are able to do that if you want your software published in the Microsoft Store, but they should allow you to do it. It's mostly intended to allow legacy applications in enterprise to in the virtualized system.
