2. ShareX
🏆 Best All-in-One Screenshot and Recording Tool
Key Features:
- Record your screen as video or GIF
- Read text from images (copy text from a screenshot)
- Automatically upload and share captures

4. EarTrumpet
Best Per-App Volume Controller
Key Features:
- Set different volume levels for each app
- Matches the Windows 11 look
- Drag and drop audio between speakers and headphones
- Lives in your system tray, always ready
Why We Like It: Microsoft should have built this into Windows. EarTrumpet lets you turn down Spotify without affecting your game sound, or mute your browser without touching everything else. Simple and essential.
5. Rainmeter
Best Desktop Customization Tool
Key Features:
- Completely redesign your desktop look
- Add live widgets showing CPU, RAM, weather, and more
- Thousands of free designs made by the community
- Uses very little memory and processing power

7. Agent Ransack
Best File Search Tool (Searches Inside Files)
Key Features:
- Search for words inside PDFs, Word documents, and text files
- Combine search terms (find files with “invoice” AND “2026”)
- Save and export your search results

Why We Like It: When Windows Search fails to find that one specific document, Agent Ransack finds it. The key difference is that it searches the contents of your files, not just the file names.
8. ClipClip
Best Clipboard Manager
Key Features:
- Saves everything you copy (text, images, files)
- Organize copied items into folders
- Search through your copy history
- Never lose a copied item again
Why We Like It: The built-in Windows Clipboard (Win+V) is limited. ClipClip saves, organizes, and lets you search through everything you have ever copied, so you never lose that important text you copied three hours ago.

Why We Like It: For users who want a fast browser without the tracking found in Chrome, Edge, and even regular Firefox. Waterfox strips out the data collection while keeping everything else you love about browsing.
13. MyPhoneExplorer
Best Android-to-PC Sync Tool
Key Features:
- Connect your Android phone to your PC over WiFi or USB
- Manage text messages, calls, and files from your computer

Why We Like It: Unlike Microsoft’s Phone Link app, MyPhoneExplorer works completely offline and keeps all your data on your computer, not in the cloud. Great for people who value privacy.

Best Free Diagram and System Planning Tool
Key Features:
- Create professional system and business diagrams
- Visualize how different parts of a project connect

Why We Like It: A specialized but essential tool for IT professionals, project managers, and system planners. It lets you map out complex structures and workflows visually, completely free.
18. FXSound
Best Free Audio Enhancer
Key Features:
- Improves all audio on your PC (music, movies, games)
- Bass boost and voice clarity settings

Key Features:
- Opens PDF files instantly (even large ones)
- Also reads ebooks (ePub, MOBI) and comic books (CBR)
- Portable version runs from a USB drive with no install

Best Free Download Accelerator
Key Features:
- Speeds up downloads by splitting files into parts

22. Advanced Renamer
Best Batch File Renaming Tool
Key Features:
- Rename hundreds or thousands of files at once
- Use photo dates or music info to build file names automatically
- Undo any rename if you make a mistake
Why We Like It: Essential for organizing messy photo folders, music libraries, or project files. You can rename 1,000 files in seconds using rules like date taken, file type, or custom patterns.
23. Eraser
Best Secure File Deletion Tool
Key Features:
- Permanently deletes files so they cannot be recovered
- Overwrites data multiple times for maximum security
- Schedule automatic secure deletion of specific folders
Why We Like It: When you delete a file in Windows, it is not really gone. Someone with recovery software could get it back. Eraser overwrites the data so sensitive files are truly destroyed beyond recovery.

Common Problems and Solutions
Windows SmartScreen blocks an app from installing
This happens with lesser-known free apps. Click “More info” then “Run anyway.” SmartScreen warns about apps it has not seen often, not necessarily unsafe ones. All apps on this list are well-established and safe.
An app runs slowly or freezes
Try running the app as administrator (right-click the shortcut and choose “Run as administrator”). Also check if your antivirus is scanning the app in real-time, which can slow things down. Adding the app to your antivirus exclusion list usually fixes this.
FXSound or EarTrumpet does not detect my audio device
Make sure your audio drivers are up to date. Go to Settings, then Windows Update, then check for updates. If the issue continues, uninstall the app, restart your PC, and reinstall. Some Bluetooth headphones need to be connected before opening these apps.
Snapdrop does not find my other device
Both devices must be on the same WiFi network. If you are using a VPN, disconnect it first. Some corporate or public WiFi networks block device-to-device connections, so try it on your home network.
AutoHotkey scripts are not working
If a script does not work in a specific app, try running AutoHotkey as administrator. Some apps (especially games) require admin-level access for scripts to interact with them. Also make sure you are using AutoHotkey v2 syntax if you downloaded v2.

I love Rain meter, have been using for the past 5 years straight. Microsoft should just include it as part of Windows.
Good point, I think slowly Microsoft will make their own built-in software like this and I think, for some reason, they will bundle it with their Copilot, basically you will be able to ask/or tell your AI what you want your wallpaper/screen to look like and it will do it.
