You can run Roblox twice on the same PC using either a second user account or a virtual machine, but the method depends on your hardware and what you want to do
Running two Roblox instances at once means opening the game twice in separate windows so you can play two different games, manage two accounts, or test something while playing. Your PC can handle this if it has enough RAM and CPU power — most modern machines do — but the setup differs based on whether you want to use one account twice or two different accounts.
The easiest route for most people is opening Roblox in your main browser and the Roblox app at the same time. If you need two separate Windows user accounts running Roblox simultaneously, you will need to use a virtual machine or run both sessions on the same account using a workaround. Each method has trade-offs in complexity and performance.
Key Takeaways
- The simplest method is running Roblox in your web browser on one window and the Roblox app in another, which works on most PCs without extra setup.
- Running Roblox on two separate Windows user accounts requires a virtual machine or remote desktop software, which demands more system resources.
- Your PC needs at least 8 GB of RAM and a mid-range processor to run two Roblox instances smoothly without lag.
- Roblox terms of service do not prohibit running multiple instances, but using multiple accounts to exploit games or gain unfair advantages violates the rules.
Browser and app method: the easiest setup
Open Roblox in your web browser (Chrome, Firefox, Edge, or Safari) in one window and launch the Roblox app from your Start menu in another. Both will run at the same time without conflict because they are separate programs accessing the same account or different accounts. This works on any PC with 8 GB of RAM or more.
To do this, log into your account in the browser version at roblox.com, then open a game. In a separate action, open the Roblox app and log in (either the same account or a different one if you have multiple). Both windows will stay open and active. You can switch between them using Alt+Tab or by clicking each window on your taskbar.
The trade-off is that both instances share your PC's resources, so performance in each game will be lower than if you were running just one. If your PC has a slower processor or less than 8 GB of RAM, you may see stuttering, lag, or crashes in one or both games.
Using two Windows user accounts with a virtual machine
If you need to run Roblox on two completely separate Windows user accounts at the same time, you will need virtual machine software like VirtualBox (free) or Hyper-V (built into Windows Pro and Enterprise editions). A virtual machine creates a second computer inside your PC, complete with its own Windows installation and user account.
read and install VirtualBox from virtualbox.org. Create a new virtual machine, allocate at least 4 GB of RAM and 30 GB of storage to it, and install Windows on it. Once Windows is running inside the virtual machine, install Roblox and log in with a second account. You can now run Roblox on your main Windows account and inside the virtual machine at the same time.
This method is more complex and slower because the virtual machine uses a portion of your PC's resources just to run a second operating system. You will need at least 16 GB of RAM on your main PC to do this comfortably. Performance will be noticeably lower in both instances compared to running a single game.
Remote desktop as an alternative for two accounts
Windows Pro, Enterprise, and Education editions include Remote Desktop, which lets you connect to your PC from another device or from another session on the same PC. You can log into your PC with one account normally, then use Remote Desktop to log in with a second account in a separate session, and run Roblox in both.
To set this up, enable Remote Desktop on your PC (search "Remote Desktop settings" in Windows), then on the same PC open Remote Desktop Connection (search "mstsc"), type your PC's name or IP address, and log in with a second user account. Roblox will run in that remote session while you play in your main session.
This method is lighter on resources than a virtual machine because it does not require a second operating system, but it still demands more CPU and RAM than the browser-and-app method. It also only works on Windows Pro and higher editions, not Windows Home.
What your PC needs to run two instances smoothly
Roblox itself is not demanding — a single instance runs on most PCs from the last ten years. Running two at once changes the math. Your processor should be at least a mid-range chip from the last five years (Intel i5 or AMD Ryzen 5 or better), and you need a minimum of 8 GB of RAM if you are using the browser-and-app method.
If you are using a virtual machine or remote desktop, add another 8 GB of RAM to that total — so 16 GB minimum. Your graphics card does not need to be powerful; Roblox uses integrated graphics on most systems. Storage space is not a constraint unless you are creating a virtual machine, which needs 30 GB or more.
To check your PC's specs, right-click "This PC" or "My Computer" on your desktop, select Properties, and look at the processor and installed RAM. If you have less than 8 GB, running two Roblox instances will be slow and may crash.
Performance tips when running two games at once
Close other programs before starting both Roblox instances. Web browsers with many tabs, Discord, streaming software, and background downloads all compete for your PC's resources. Closing them frees up RAM and CPU power for Roblox.
Lower the graphics settings in both games. In Roblox, open Settings (gear icon), go to Graphics, and move the Graphics Quality slider down. This reduces the load on your GPU and CPU. You can also cap your frame rate at 30 or 60 FPS instead of unlimited to save processing power.
If you are using a virtual machine, allocate more RAM to it in the settings. Open VirtualBox, right-click your virtual machine, select Settings, go to System, and increase the Base Memory slider. Give it at least 4 GB, but leave at least 8 GB for your main Windows installation.
Roblox terms of service and account rules
Roblox does not prohibit running multiple instances of the game on one PC. You can legally run the browser version and the app at the same time, or use two accounts on two separate Windows sessions. The restriction comes only if you use multiple accounts to cheat, exploit games, or gain unfair advantages — for example, using two accounts to farm currency or bypass game rules.
If you are running two instances to play two different games casually or to manage two separate accounts, you are within the rules. If you are using them to manipulate a single game or farm rewards, Roblox may ban your accounts. The platform monitors for this kind of abuse and enforces it through account suspension or permanent bans.
Frequently Asked Questions
Will running two Roblox games at once get my account banned?
No, running two instances is not against the rules. Roblox only bans accounts for cheating, exploiting, or using multiple accounts to gain unfair advantages within a game. Playing two separate games or managing two accounts fairly is permitted.
Can I run Roblox twice on a laptop?
Yes, if your laptop has at least 8 GB of RAM and a mid-range processor. Laptops with less RAM or older processors will experience lag or crashes. Check your laptop's specs before trying — gaming laptops and newer business laptops usually have enough power, but budget or older models may not.
What is the difference between the browser and app versions of Roblox?
The browser version runs through your web browser and does not require installation. The app is a standalone program you read from the Microsoft Store or Roblox.com. Both access the same games and accounts, but the app sometimes performs slightly better because it does not share resources with browser tabs.
Do I need two Roblox accounts to run two instances?
No. You can log into the same account in both the browser and the app, or use two different accounts if you have them. Running the same account twice is allowed, though you will be logged in from two places at once.
Will my internet connection slow down if I run two Roblox games?
Possibly, but only if your internet speed is already slow. Each Roblox game uses a small amount of bandwidth. If you have a connection slower than 10 Mbps, running two games might cause lag. Most home internet connections (25 Mbps or faster) handle two instances without noticeable slowdown.
