Can I register a custom URL scheme without Administrator elevation?

Question

There are many stack overflow questions about how to register a custom URL scheme (e.g. this one). However, the answer in every case seems to be to write to the privileged registry key HKEY_CLASSES_ROOT. My (wix-based) installer currently runs without elevation, installing per-user. Is there any way I can register a custom URL scheme without elevating to administrator privileges? I don't need to support anything older than Windows 7.

What I'm trying to achieve is to have links on a web page that perform specific actions in my application. My application is mostly .NET. The web page is ASP.NET.

I found the answer in this answer to a similar question. As an alternative to HKEY_CLASSES_ROOT, put the appropriate registry keys under HKEY_CURRENT_USER\Software\Classes. This location does not require elevation to write to.
