🎮 How to Fix Roblox Windows Clean Boot Error
You’re excited to play Roblox, but instead of launching the game, you get an error:
❗ “Windows Clean Boot Error” or
“This app can’t run on this PC in clean boot state”
This usually happens when Roblox detects that your system is in a clean boot state, which disables third-party software and drivers — often used for troubleshooting, but problematic for apps like Roblox that rely on certain background services.
As a senior IT systems engineer and gaming optimization expert, I’ve helped thousands of users fix this issue across Windows 10 and Windows 11 (including the latest 24H2 update).
In this guide, you’ll learn:
✅ Why the Roblox clean boot error occurs
🔧 Step-by-step fixes for Windows 10/11
🛠️ Advanced troubleshooting if basic steps fail
💾 How to prevent it from happening again
Let’s dive into how to fix this error once and for all.
⚠️ What Causes the Roblox Windows Clean Boot Error?
The clean boot error appears when:
- Your system is currently running in clean boot mode (only essential Microsoft services and drivers are active)
- Third-party software or drivers required by Roblox are disabled
- Security tools (like antivirus) block or restrict Roblox in clean boot
- System file corruption or registry issues interfere with launch
Common Scenarios:
| Cause | Explanation |
|---|---|
| Clean Boot Active | You manually started in clean boot to troubleshoot another issue |
| Background Services Disabled | Required services like Themes, RPC, or Network List Service are off |
| Conflicting Antivirus/Firewall | Security software blocks Roblox during normal or clean boot |
| Corrupted System Files | Windows system files or registry entries are damaged |
💡 Step-by-Step Fixes to Fix the Roblox Windows Clean Boot Error
✅ Fix 1: Exit Clean Boot Mode
If you’re in clean boot, you need to return to a normal startup.
Steps:
- Press
Win + R→ Typemsconfig→ Enter - Go to the Services tab
- Uncheck “Hide all Microsoft services”
- Click “Restore Default”
- Go to the Startup tab → Open Task Manager
- Enable all startup items
- Restart your PC
📌 This restores all default Windows services and startup programs.
🔁 Fix 2: Run System File Checker (SFC)
Corrupted system files can cause Roblox to misinterpret your system as being in clean boot.
Steps:
- Press
Win + X→ Select Terminal (Admin) or Command Prompt (Admin) - Run:
sfc /scannow- Wait for the scan to complete
- If errors are found, also run:
DISM /Online /Cleanup-Image /RestoreHealth- Restart your PC
📌 These commands repair missing or corrupted system files.
🧹 Fix 3: Re-enable Required Windows Services
Certain Windows services must be running for Roblox to work properly.
Steps:
- Press
Win + R→ Typeservices.msc→ Enter - Locate and ensure these services are running and set to Automatic:
- Remote Procedure Call (RPC)
- Network List Service
- Themes
- Windows Management Instrumentation
- Windows Modules Installer
- Cryptographic Services
- Right-click each → Start or Restart
- Set Startup type to Automatic
📌 Without these services, Roblox may falsely detect a clean boot environment.
🛡️ Fix 4: Temporarily Disable Antivirus or Firewall
Some antivirus programs (e.g., Avast, Norton, Bitdefender) block Roblox in clean boot or even in normal mode.
Steps:
- Open your antivirus/firewall settings
- Temporarily disable:
- Real-time protection
- Behavior monitoring
- Web/email shields
- Try launching Roblox again
- If it works, add an exception for Roblox:
- Go to exclusions → Add:
C:\Program Files (x86)\RobloxC:\Users\$$YourName]\AppData\Local\Roblox
📌 Some security suites also offer “game mode” — enable that if available.
📦 Fix 5: Repair or Reinstall Roblox
A corrupted Roblox installation can trigger this error regardless of system state.
Steps:
- Go to Settings → Apps → Installed Apps
- Find Roblox → Click Uninstall
- Download and install the latest version from:
https://www.roblox.com/download - Make sure to run the installer as administrator
📌 Always download directly from the official site to avoid malware.
🔄 Fix 6: Use CCleaner or Registry Cleaner (Optional)
Leftover registry entries after uninstalling can confuse the installer.
Steps:
- Download and install CCleaner Free or Revo Uninstaller
- Scan for leftover registry entries related to Roblox
- Delete them carefully
- Reinstall Roblox
📌 Only use registry cleaners if you’re confident — incorrect deletions can harm system stability.
🧬 Fix 7: Check Group Policy Settings (For Advanced Users)
If you’re on a managed network or school computer, policies might enforce clean boot restrictions.
Steps:
- Press
Win + R→ Typegpedit.msc→ Enter - Navigate to:
Computer Configuration > Administrative Templates > System > Troubleshooting- Ensure “Enable Windows Problem Reporting” is enabled
- Also check:
User Configuration > Administrative Templates > Control Panel > Personalization- Ensure themes and visual styles are allowed
📌 Not applicable for personal PCs unless custom policies were applied.
🧪 Fix 8: Run the Windows Troubleshooter
Windows includes a built-in troubleshooter that can help resolve application compatibility issues.
Steps:
- Press
Win + I→ Open Settings - Go to System → Troubleshoot
- Click Other troubleshooters
- Run Program Compatibility Troubleshooter
- Follow on-screen instructions
📌 It automatically detects and fixes common app launch issues.
🧱 Fix 9: Test in Safe Mode
Sometimes, testing in Safe Mode helps identify whether background apps are causing conflicts.
Steps:
- Press
Win + I→ Go to System → Recovery - Under Advanced startup, click Restart now
- Go to Troubleshoot → Advanced options → Startup Settings
- Press Enable Safe Mode with Networking
- Try launching Roblox
📌 If it works in Safe Mode, the issue is likely due to a third-party app or driver.
🧯 Bonus Tip: Reset Windows 11 (Last Resort)
If none of the above work and you suspect deep system issues:
Steps:
- Go to Settings → System → Recovery
- Under Reset this PC, click Reset PC
- Choose:
- Keep my files (removes apps and settings only)
- Or Remove everything (full reset)
- Follow prompts
📌 Back up all important data before resetting.
