Features and specs

What each product offers, as listed by its team.

CalculatorSpan 5 features
ShellNewHandler 0 features
  • Free to Use
    CalculatorSpan offers its suite of calculators without any subscription fees or paywalls, making it accessible to anyone who needs quick calculations for finance, health, math, or other categories.
  • Wide Range of Calculators
    The site typically covers multiple categories such as financial, health, math, and conversion calculators, allowing users to find various tools in one place rather than searching multiple websites.
  • Simple Interface
    The tools are generally designed with straightforward input fields and clear instructions, making them easy to use even for people who are not tech-savvy.
  • No Registration Required
    Users can typically access and use the calculators immediately without needing to create an account or provide personal information, which speeds up the process and protects privacy.
  • Mobile Friendly
    Many calculator websites like this are optimized for mobile browsers, allowing users to perform calculations on their phones or tablets while on the go.

Possible disadvantages

  • Limited Advanced Features
    Free online calculator tools often lack the depth and customization options found in specialized software or paid financial/health calculation tools, which may not satisfy professional or advanced users.
  • Ad-Supported Model
    Since the site is free, it may rely on advertisements for revenue, which can clutter the interface and slow down page load times.
  • Accuracy Concerns
    As with many free online calculators, there may be limited transparency about the formulas or methodologies used, making it harder for users to verify the accuracy of results for critical financial or medical decisions.
  • Lack of Personalization
    The calculators are generally generic and may not account for individual circumstances or regional variations, such as tax laws or currency differences, unless specifically built for that purpose.
  • Limited Support or Documentation
    There may be minimal customer support or detailed explanations behind each calculator, leaving users without guidance if they have questions about how results are calculated.

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

  • 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
