FAQs (Frequently Asked Questions)

Q1: Can you get banned for using multi Roblox?

No, you will not get banned for simply running multiple Roblox instances, as long as you are not using any exploit programs or modifying the game’s memory. Roblox allows players to log into multiple accounts, and multi-instance tools only help you open more than one game window at a time. As long as you avoid exploit injectors or cheating software, multi-Roblox usage is completely safe.

Q2: Why does Roblox close my second instance?

Roblox automatically enforces a single-instance mode, which means it closes any additional game windows you try to open. This is part of Roblox’s default behavior to prevent multiple clients from running at once. You can bypass this restriction by using tools like MultiBloxy or Process Explorer, which safely allow multiple game instances to stay open at the same time.

Q3: What is the best multi-Roblox tool in 2025?

The most reliable tools for running multiple Roblox windows in 2025 are MultiBloxy and Process Explorer. MultiBloxy is easy for beginners and works with just a single click, while Process Explorer is an official tool from Microsoft that offers a very safe way to open multiple instances. Both methods are trusted and work consistently with the latest Roblox updates.

Q4: How many Roblox windows can my PC handle?

The number of Roblox windows you can run depends entirely on your computer’s hardware—mainly the CPU and available RAM. A system with 8GB of RAM can usually handle around 2 to 4 instances comfortably, while a PC with 16GB can run between 5 and 10 instances. High-end setups with 32GB of RAM or more can often handle 10 or more Roblox windows without performance issues.
