No analysis of DNSDoctor.dev yet.

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 DNSDoctor.dev and ShellNewHandler.

What makes your product unique?

DNSDoctor.dev's answer

The fix records are generated by a deterministic engine that validates them against the actual RFC grammar and the 10-lookup limit. The AI only writes the plain-English explanation; it never writes the record itself. Most tools either show you charts and leave the fix to you, or let a language model guess at DNS records, which fails silently when the guess is wrong. We also check things the DMARC-only tools skip: blacklists, reverse DNS, domain and SSL expiry.

Why should a person choose your product over its competitors?

DNSDoctor.dev's answer

The free scan needs no signup and gives you the full picture in one page, with the exact record to paste for each problem. The paid side answers the question most report dashboards leave open: is it safe to move to p=reject yet? It reads your DMARC reports, tracks every sending source, and tells you when the evidence supports the next policy step. One flat plan, no per-message metering, no sales call.

How would you describe the primary audience of your product?

DNSDoctor.dev's answer

Small business owners and IT folks whose email quietly lands in spam, sysadmins who want DMARC enforcement without reading XML, and MSPs managing email auth across many client domains. Also works for AI agents: there is a REST API and an MCP server, so you can run scans from your own tools.

What's the story behind your product?

DNSDoctor.dev's answer

Side project by a founder who manages domains for a few companies he supports. The pattern kept repeating: marketing signs up for some new tool, it starts sending as the domain, nobody added it to SPF, and mail disappears until a customer complains. Raw DMARC reports technically contain the answer, but nobody reads gzipped XML. So this became the tool: scan, get the exact record to fix, and monitoring that flags a new sender the day it appears.

Which are the primary technologies used for building your product?

DNSDoctor.dev's answer

Python does the heavy lifting, with the DMARC report pipeline built on proven open-source parsing libraries rather than being reinvented. The part that matters is architectural: record generation is plain deterministic code that validates against the RFC grammar, and the AI layer is only allowed to write explanations, never records.

  • 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
