Is it true that rustup does not use the Windows registry?

I want my rustup installation to work on any Windows device with VS buildtools and Clang support by simply adding environment variables, and can use rustup normally for upgrades, adding targets, etc. A previous post said that rustup does not use the Windows registry, but I found that it adds an item to the installed program list. Is this optional and does rustup have any other side effects on the system other than environment variables?

the installed program list item

The post you linked to is nearly 6 years old. Perhaps it was true back then, but rustup definitely uses the Windows registry now:

Any options are considered to disable these behaviors?

Seems that there are none for now, after searching in issues.

Looks like it isn't done if during installation you answer no to "Modify PATH variable?".
