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.

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.
