Analysis

ShellNewHandler

Overall verdict

  • ShellNewHandler is a niche, lightweight utility hosted on SourceForge designed to give users more control over the Windows 'New' context menu (the ShellNew menu). It can be considered good for its specific narrow use case, but it is an older, minimally maintained tool that may not suit all users, especially those on modern Windows versions.

Why this product is good

  • Provides direct control over customizing the Windows right-click 'New' menu, allowing users to add or remove file type entries
  • Lightweight and free, without bundled bloatware typical of some other free utilities
  • Simple and focused in scope, making it easy to understand for its specific purpose
  • Open distribution via SourceForge allows transparency and no-cost access

Recommended for

  • Power users who want to declutter or customize the Windows New context menu
  • IT administrators managing standardized desktop environments across multiple machines
  • Users comfortable with older utility-style tools and Windows registry-related tweaks
  • Not recommended for casual users seeking modern, actively supported software with regular updates

Questions & Answers

As answered by people managing ShellNewHandler and username.md.

What makes your product unique?

username.md's answer:

username.md gives people and AI agents an internet identity they actually own. Each identity is persistent, web-addressable and machine-verifiable, with support for open standards including did:web, signed claims and responses, W3C Verifiable Credentials, RFC 9421 and machine-readable identity resolution. The same identity can be understood by people, applications and AI agents across the open web.

Why should a person choose your product over its competitors?

username.md's answer:

Unlike platform-specific profiles or identifiers, username.md is designed to be portable and independently verifiable. Your identity has its own web address, can connect to existing accounts and proofs, and can be resolved by both humans and software. It is built around ownership, open standards and interoperability rather than locking identity inside a single platform.

How would you describe the primary audience of your product?

username.md's answer:

username.md is built for people, developers, businesses and AI-agent builders who need persistent, portable and verifiable digital identity. It is especially relevant for developers building AI agents and applications that need to resolve and verify identity programmatically across platforms and environments.

Which are the primary technologies used for building your product?

username.md's answer:

username.md uses open identity and web standards including did:web decentralized identifiers, Ed25519 cryptographic signatures, RFC 9421 HTTP Message Signatures, W3C Verifiable Credentials, JSON-LD, JWS, OpenAPI 3.1 and MCP-based identity resolution and verification.

What's the story behind your product?

username.md's answer:

Chris has imagined the idea of a universal identity for quite some time. He wrote a blog post about the topic in 2022 and the idea persisted.

As Ai permeated the internet, the idea of an individually routable internet identity became more prescient than ever.

Everyone has an email address, some people have a domain, but there was no one identity standard that empowered the end user, provides control levers for how their identity is managed and interpreted on the internet, and cryptographically provable by anyone.

username.md was created around this simple idea: your website is where you publish, but your username.md is who you are. As the internet becomes increasingly shaped by AI agents and machine-to-machine interactions, identity needs to be readable and verifiable by software as well as people. username.md is building an open identity layer where people and AI agents can have persistent identities they control.

Who are some of the biggest customers of your product?

username.md's answer:

username.md serves individuals, developers, businesses and AI-agent builders. We do not publicly disclose individual customer names.

  • I recently got libreoffice, but now the new option in right click looks like a mess. Can someone help me get rid of them please?
    Use Shell New Handler. Run the portable app and simply untick the items you don't want to appear in your new context menu. Source: about 4 years ago
  • This menu should be easy to add/remove programs to... Who is really creating Access Databases from this menu often enough to keep it here? (Not me!) Is there an easy way to edit this?
    I've always used ShellNewHandler for this. It's a really simple portable utility that allows you to remove most of the items from that menu. Tested it out on Windows 11 and it's still compatible. Source: over 5 years ago
