How to Use the USB Tool
📌 Once you have your USB ready, follow these simple steps:
- Insert the USB into the computer that has the problem.
- Wait a few seconds until it appears in "My Computer".
- Open the USB and select the folder you need (e.g. "Antivirus", "Repair" or "Recovery").
- Find the file ending in .exe and do double click.
- If a confirmation window (User Account Control) appears, click "Yes".
- For portable tools that don't require installation, simply run them from the USB folder without copying them to your computer.
If the computer does not start Windows, you can:
- Presses F2, F12 ή TIME when the computer is turned on (depending on the model).
- An options menu will open — this is called the BIOS or Boot Menu.
- Select USB as the first boot option (Boot Priority) to run the tools directly from USB.
- If you have installed tools like Hiren's BootCD or portable antivirus, you can repair or scan the system even when Windows won't start.
- Some tools such as drivers or file recoveries require running with right click → Run as administrator for full functionality.
Safety Tips
Keep your USB safe and clean:
- Don't lend it to others — it may be infected with viruses or malware.
- Scan it regularly with antivirus to make sure it's clean.
- Keep a backup of the tools in a folder on your computer or in the cloud.
- Update programs every 3-6 months by downloading the latest versions.
- For greater security, create folders with protection or password if they contain sensitive tools or data.
- Be careful with files you download from the Internet — always download them from official or trusted sources.
Additional Tips
Make USB even more useful:
- Insert a text file with the title
ΟΔΗΓΙΕΣ.txtwhere you can write down what each tool does, so you can easily remember how to use them. - Also keep some basic drivers (e.g. for Wi-Fi or graphics card) in a separate folder.
- If you have enough space, also insert a Windows Installation Media (you can create it with Microsoft's Media Creation Tool) to reinstall Windows.
- Add portable versions of programs you use frequently, e.g. Google Chrome Portable or VLC Portable.
FAQ
A 16GB USB is enough for basic tools. If you want to put Windows Installation Media, portable programs, or lots of additional tools, opt for a 32GB or 64GB USB.
Most tools are compatible with Windows 7, 8, 10, and 11. Some older ones may not work on Windows 11, so we always choose the updated versions.
Of course! You can use the remaining space for files, photos or backups. Just don't accidentally delete the tool folders and be careful not to get infected with viruses.
It is a good idea to download the latest versions of antivirus every 3-6 months, while you can update the other tools once a year to ensure they are fully functional.
Try running it "as administrator" (right click → "Run as administrator"). If it still doesn't work, it may need to be installed, upgraded .NET or Visual C++ redistributable, or it is not compatible with your version of Windows.
