Fast Reaction Test VS ShellNewHandler

• Simple and instant to use
  The test runs directly in the browser with no installation, sign-up, or setup. Users can start measuring their reaction time within seconds, which makes it very accessible for casual use.
• Free to use
  The site is generally free, so anyone can check their reaction time as often as they like without a subscription or payment.
• Quick feedback and easy benchmarking
  Results appear immediately in milliseconds, letting users compare their scores across attempts or against averages. This is handy for fun competitions with friends or tracking rough improvement over time.
• Works across devices
  Because it is a lightweight web-based tool, it can be used on desktops, laptops, tablets, and phones with a standard browser, so users can try it wherever they are.
• Useful for practice and awareness
  Gamers, athletes, and curious users can use it as a simple warm-up or to get a general sense of their visual reaction speed. It also works as a fun, low-pressure way to learn about human reaction times.

Possible disadvantages

• Results affected by hardware and latency
  Screen refresh rate, input device lag, browser performance, and network or system delays add to the measured time. Scores can vary between devices and may not reflect true neurological reaction speed.
• Not scientifically validated
  It is an informal online test, not a clinical or research-grade tool. Results should not be used for medical, diagnostic, or professional performance assessment.
• Limited scope and depth
  It typically measures only a single simple visual reaction, with no choice-reaction tasks, auditory tests, or detailed analytics. This limits its value for deeper training or analysis.
• Limited tracking and features
  Basic tools like this often lack accounts, detailed history, progress charts, or robust leaderboards. Users who want to monitor long-term improvement may need to record scores manually or use another tool.
• Possible ads and inconsistent results
  Free sites may display advertising that can distract or affect page performance. Individual results also fluctuate with attention, fatigue, and anticipation, such as clicking early, so single scores are not very reliable.

• 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
