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 AspectCalc and ShellNewHandler.

Which are the primary technologies used for building your product?

AspectCalc's answer

HTML, CSS, JavaScript

Why should a person choose your product over its competitors?

AspectCalc's answer

Most aspect ratio calculators only do simple division and stop there. AspectCalc adds a live preview so you can visually confirm a crop or resize before committing, a "closest standard ratio" check for imprecise resolutions, and a one-click CSS export — all with no sign-up and no ads.

What makes your product unique?

AspectCalc's answer

It handles both directions of the aspect ratio problem in one tool — calculating the ratio from a given size, and resizing to a target ratio — with a live visual preview that shows the actual shape as you type, not just numbers. It also flags how close a non-standard resolution is to the nearest common ratio (useful for catching things like a "16:9" screen that's actually slightly off), and lets you copy the CSS aspect-ratio property in one click.

How would you describe the primary audience of your product?

AspectCalc's answer

Content creators, video editors and social media managers who need to resize content across platforms with different aspect ratios (Instagram, TikTok, YouTube), along with designers and front-end developers who need exact ratio math for layouts and CSS.

What's the story behind your product?

AspectCalc's answer

Built out of a recurring personal annoyance — manually calculating aspect ratios every time a video or image export needed to fit a different platform's required shape. Rather than doing the division by hand each time, AspectCalc turned that into a tool that handles both directions of the calculation with a live preview.

  • 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
