Some people have found Windows 11 to be bloated with a lot of unnecessary files and apps that only slow down the OS. At least to these people as Windows 11 does come with genuinely great apps.
Gamers have also found that, because of the perceived Windows 11 bloat, a lot of their games don’t run as well as they should. So, people took the Windows 11 ISO file from Microsoft and created their own version.
This guide will show some of the best custom ISO files for Windows 11. Across the internet, many of them are compact and easy on the hardware.
What are the best custom ISO files for Windows 11?
Ghost Spectre
Ghost Spectre Superlite is a custom Windows 11 version focused on speed and performance. It removes resource-heavy features like OneDrive, Windows Defender, and NFC.
Benchmarks show smoother gameplay in demanding titles like Cyberpunk 2077, thanks to reduced bloat.
We like its focus on performance but caution: losing security features may leave some users feeling exposed. Still, it’s a fantastic choice for power users seeking peak efficiency.
Pros:
- Unparalleled performance boost
- Lightweight and resource-friendly
- Excellent for gaming on modest hardware
Cons:
- No Windows Defender or updates
- Limited customization for casual users
ReviOS
ReviOS is built for gamers and power users, cutting excess baggage like typing personalization, UAC, and unnecessary services.
It balances minimalism and functionality by keeping essentials like Xbox Game Bar and optional updates. We especially enjoy the Workspace feature for post-installation tweaks, making it feel personal and efficient.
Though lighter than Windows 11, you’ll want an antivirus since Defender’s out. Overall, ReviOS delivers solid customization and seamless gaming.
Pros:
- Customization right after setup.
- Retains important features like Xbox Game Bar.
- Easier on system resources (3.56GB ISO).
Cons:
Might require more post-install tweaking.
No built-in antivirus.
Phoenix Lite OS
Phoenix Lite OS removes unnecessary features but stands out by bypassing TPM and Secure Boot, broadening compatibility.
Versions like Ultra-Lite retain basics like Microsoft Store and pre-install useful frameworks. What caught our attention is its efficiency: reworked Bluetooth support and pre-installed tools make it ready to go.
While it lacks Hyper-V, its stripped-down design keeps functionality intact. Perfect for older or underpowered hardware.
Pros:
- Bypasses TPM/Secure Boot requirements
- Pre-installed DirectPlay and .NET Framework 3.5
- Lightweight and efficient
Cons:
- No Hyper-V, limiting Android app support
- Less versatile for professional tasks
