Windows feature updates 11 aren’t simple patches, but full-fledged new versions of the operating system that introduce new features, performance improvements, and security updates, as the 26H2 of Windows 11.
In a couple of weeks, the new version of Windows 11, called 26H2, so it’s essential to make sure your PC is compatible and ready before proceeding with the installation, to avoid errors or interruptions during the process.
Why is checking compatibility essential?
- Updated drivers: outdated or incompatible drivers can cause instability or crashes, or make peripherals such as printers, graphics cards, or sound cards unusable.
- Manufacturer support: manufacturers such as Intel, AMD, NVIDIA, ASUS, Dell, Lenovo, and others release drivers specifically optimized for new versions of Windows. Updating them reduces the risk of malfunctions.

- Back up your data: save your most important files to an external drive or OneDrive/another cloud service.
- Check hardware compatibility:
- CPU: check whether your processor is still supported by Microsoft for 25H2.
- RAM: minimum 4 GB, at least 8 GB recommended.
- Disk space: make sure you have at least 10–20 GB free for the update.
- GPU and peripherals: check for updated drivers for your graphics card, network card, audio devices, and printers.
👉 Useful resource: Will my computer support Windows 11?
- Update your drivers: download the latest versions from your PC manufacturer’s website or from the websites of individual component manufacturers.

- Third-party antivirus software: many updates fail because of external security software.
- First disable your antivirus, and if problems persist, consider temporarily uninstalling it.
- Keep your activation code handy so you can reinstall it afterward, if necessary.
Managing disk space
- Use Settings > System > Storage to check what is taking up the most space.
- Delete temporary files or apps you don’t need.
- If needed, connect an external USB drive: Windows can use it as temporary storage for the installation.
Practical tips during installation
- Disconnect from the internet: turn off Wi-Fi or unplug the network cable to reduce possible errors during the update.
- Remove unnecessary USB peripherals: such as printers, scanners, webcams, or external drives.
- Check for errors with SetupDiag: if the installation fails, you can use Microsoft’s official tool to find out why.
