The default location scoop installs programs to (which can be changed) is not in the system files directories, but the user directories eg.
C:\Users\<user>\scoop. This avoids a lot of problems to do with
PATH and UAC permissions, especially if you stick to the main scoop bucket. winget somewhat “supports” it, but it depends on each individual application supporting a
--location parameter instead of having a global install location (eg. different drives).
Also winget also does not support installing of portable applications, which is the main type of programs that scoop targets.
So I’m not so sure winget will make scoop redundant, at least until it manages to implement these features. I am especially skeptical about the portable applications one. To me, winget is still more focused on .exe and .msi installers as the target applications.
