¿Qué debe hacer?

• Verifique si su PC es compatible con Windows 11 con la herramienta PC Health Check de Microsoft.
• Actualice a Windows 11 si su sistema cumple con los requisitos.
• Considere otras opciones, como extender el soporte a través de las Actualizaciones de seguridad extendidas (ESU) de Microsoft para empresas.

Realice una copia de seguridad de sus datos antes de realizar actualizaciones o cambios.

¡Prepárese y manténgase seguro! No esperes hasta el último minuto para hacer la transición. Si necesitas ayuda con la actualización o la planificación, ¡no dudes en comunicarte con nosotros!

Windows 10 End of Support

Windows 10 End of Support – What You Need to Know

Microsoft has officially announced that Windows 10 will reach its end of support on October 14, 2025. This means no more security updates, bug fixes, or technical support from Microsoft. If you’re still using Windows 10, it’s time to start planning your upgrade to Windows 11 or explore alternative solutions.

Why does this matter?

• Security Risks – No more updates means increased vulnerability to cyber threats.
• Software Compatibility – New applications may stop supporting Windows 10.
• Performance Issues – Outdated systems can lead to decreased efficiency and reliability.

What should you do?

• Check if your PC is compatible with Windows 11 using Microsoft’s PC Health Check tool.
• Upgrade to Windows 11 if your system meets the requirements.
• Consider other options, such as extending support via Microsoft’s Extended Security Updates (ESU) for businesses.

Backup your data before making any upgrades or changes.

Stay prepared and secure! Don’t wait until the last minute to make the transition. If you need assistance with upgrading or planning, feel free to reach out!

HOW TO INSTALL LINUX ON AN OLD COMPUTER

HOW TO INSTALL LINUX ON AN OLD COMPUTER

To install Linux on an old computer, you need to download a Linux distribution (like Ubuntu or Linux Mint), create a bootable USB drive using a tool like Rufus, boot your computer from the USB, and follow the on-screen instructions to install Linux on your desired partition, choosing a lightweight distribution that is optimized for older hardware if necessary; remember to back up any important data before proceeding as the installation process may overwrite existing files on your hard drive.

Key steps:

1. Choose a Linux distribution: Select a lightweight Linux distribution designed for older hardware, like Xubuntu, Lubuntu, or Debian.

2. Download the ISO image: Go to the chosen Linux distribution's website and download the latest ISO file.

3. Create a bootable USB drive: 1) Use a tool like Rufus or UNetbootin to write the ISO image to a USB drive. 2) Ensure your USB drive is formatted properly.

4. Boot from USB: 1) Insert the USB drive into your old computer. 2) Access your BIOS settings by pressing the appropriate key during startup (usually F2 or Del). 3) Change the boot order to prioritize the USB drive.

5. Start the installation process: 1) When the computer boots from the USB, you will be presented with a live Linux environment. 2) Select your language and keyboard layout. 3) Choose "Install Now" and follow the on-screen instructions.

6. Partition your hard drive: 1) Decide if you want to install Linux alongside your existing operating system (dual boot) or completely replace it. 2) Allocate sufficient disk space for your Linux installation.

7. Complete the installation: 1) Set your username, password, and other preferences. 2) The installer will format the selected partition and install Linux.

Important considerations:

• Backup your data: Before installing Linux, ensure you have backed up any important files from your old computer.

• Check hardware compatibility: While most modern Linux distributions work well with older hardware, check if your specific components are fully supported.

• Adjust settings for performance: Once installed, you may need to tweak settings like the desktop environment to optimize performance on older hardware.
