I recently downloaded the X-Lite- Optimum 10 Pro v5.iso and installed it on a budget Celeron laptop with only 4GB of RAM. Here is my honest review. The "Optimum" line is X-Lite’s flagship build. Version 5 is the latest iteration as of early 2026. It is based on Windows 10 Pro (22H2) but feels like a completely different operating system.
However, remember the golden rule of custom ISOs: (or your preferred AV) before running it, and never use it for online banking unless you have reinstalled Defender or installed a third-party AV like Bitdefender. -- X-Lite- Optimum 10 Pro v5.iso
8.5/10 (Docked 1.5 points for the biometrics removal and security caveats). Disclaimer: I am not affiliated with the creator of X-Lite. Custom ISOs void your Windows license and come with potential security risks. Install at your own risk. I recently downloaded the X-Lite- Optimum 10 Pro v5
