Launch Multiple Roblox Windows
Run more than one Roblox window at the same time on Windows 10 or 11. GuIltyHub uses proper mutex isolation so windows do not interfere with each other.
Why use GuIltyHub?
Mutex Isolation
Each Roblox window gets its own isolated mutex so they don't fight over the same process lock.
BrowserTrackerID Handling
Each instance gets a fresh BrowserTrackerID so Roblox treats them as separate sessions.
No Crashes
Properly isolated processes mean one window crashing doesn't take the others down.
Low Memory Footprint
Tuned for running many instances on average hardware without ballooning RAM.
One-Click Launch
Launch every account in your list with one click — no manual exe juggling.
Per-Window Logs
Each window writes to its own log file for easy debugging and reconnection.
Frequently Asked Questions
How is this different from Roblox's built-in multi-instance?
Roblox does not officially support multi-instance. GuIltyHub safely handles the mutex Roblox uses to prevent multiple instances.
Will my PC explode if I run 20 windows?
No, but expect 1-3 GB of RAM per window. 16 GB of RAM is comfortable for around 8-10 instances.
Does it work on Windows 11?
Yes, fully supported on Windows 10 and Windows 11. macOS support is being researched.
Can I close just one window without affecting others?
Yes. Each instance is fully independent. Close any window without disrupting the others.
