Installing Windows 11 on unsupported devices has become a common need for users who own slightly older PCs or laptops. Microsoft introduced strict requirements such as TPM 2.0, Secure Boot, and newer-gen CPUs, which instantly made millions of devices “incompatible.”
But let’s be honest your PC is still capable, fast, and perfectly usable. The only problem? Microsoft wants to enforce restrictions.
The good news?
You can install Windows 11 on unsupported devices easily, safely, and without any complicated hacking as long as you follow the correct method.
This guide covers everything:
- How to bypass TPM, Secure Boot & CPU check
- How to upgrade without losing data
- How to do a clean install
- How to fix common installation errors
- How to keep Windows 11 stable on older hardware
Let’s begin.
Why Your PC Shows “Unsupported” for Windows 11
Microsoft requires a few hardware components to officially allow Windows 11 installation:
1. TPM 2.0 (Trusted Platform Module)
Most older laptops only have TPM 1.2 or none at all.
2. Secure Boot
Older BIOS versions may not support it, or it may be turned off.
3. Supported CPU List
Windows 11 only supports:
- Intel 8th gen or newer
- AMD Ryzen 2000 or newer
If your PC has:
✔ Intel 6th, 7th gen
✔ AMD FX, older Ryzen
✔ Older Pentium/Celeron
it will show:
“This PC can’t run Windows 11.”
4. 4GB RAM (Minimum)
Rufus can bypass this too if you have lower RAM.
What You Need Before Installing Windows 11
Before you begin, prepare these basic requirements:
✔ A Windows 11 ISO
Download the official ISO from Microsoft.
✔ A USB Drive (8GB or more)
It will be formatted, so backup data.
✔ Rufus (To create the bootable USB)
Rufus includes built-in bypass options for unsupported hardware.
✔ Backup Your Files
Always recommended when installing an OS.
Method 1: Install Windows 11 on Unsupported Devices Using Rufus (Best & Easiest Method)
This is the safest and most popular way to install Windows 11 on unsupported hardware in 2025.
Step 1: Download Rufus
Download the latest version of Rufus from its official website.
Step 2: Plug In Your USB
Insert your USB drive (8GB+).
Step 3: Select the Windows 11 ISO
Open Rufus
Click SELECT and choose the Windows 11 ISO.
Rufus will auto-detect the USB and ISO.
Step 4: Choose Partition Scheme
Use these options:
- Partition Scheme: GPT
- Target System: UEFI
If you have an old BIOS PC, choose MBR + BIOS/UEFI.

Step 5: This Is the Important Part Bypass Options
Rufus will show a pop-up asking:
“Would you like to remove requirement checks?”
Tick everything:
✔ Remove requirement for TPM 2.0
✔ Remove requirement for Secure Boot
✔ Remove requirement for supported CPU
✔ Remove requirement for at least 8GB RAM
✔ Disable Microsoft Account requirement
✔ Skip online setup
These options make your PC fully compatible.
Step 6: Create the USB
Click Start. Rufus will prepare the USB.
Once completed, your USB is ready for installation.
Method 2: Upgrade to Windows 11 Without Losing Data (Bypass Registry Checks)
If you prefer to upgrade directly from Windows 10 without a clean install, follow this method.
Step 1: Download the Windows 11 ISO
Mount the ISO by double clicking it.
Step 2: Run Setup.exe
The installer will open.
You will likely see:
“This PC can’t run Windows 11.”
Don’t worry, continue.
Step 3: Open Registry Editor to Bypass Checks
Press:
Shift + F10 → Command prompt opens
Type: regedit
Then go to:
HKEY_LOCAL_MACHINE\SYSTEM\Setup
Right-click → New → Key → name it:
LabConfig
Inside LabConfig, create these DWORDs (32-bit):
- BypassTPMCheck → value: 1
- BypassSecureBootCheck → value: 1
- BypassCPUCheck → value: 1
- BypassRAMCheck → value: 1 (optional)
Close everything → restart Setup.exe.
Windows 11 installation will now run normally.
Method 3: Clean Install Windows 11 on Unsupported PC
If you want a fresh installation:
Step 1: Restart Your PC
Plug in your bootable USB.
Step 2: Enter Boot Menu
Use one of these keys depending on your laptop brand:
- Dell → F12
- HP → ESC or F9
- Lenovo → F12
- Acer → F12
- Asus → F8/F12
- Generic → F11
Step 3: Select USB Boot
Choose your USB drive from boot options.
Step 4: Begin Windows Installation
Since Rufus already bypassed restrictions, installation will continue without errors.
Select:
- Language
- Edition
- Drive
Complete installation normally.
Fix Common Errors While Installing Windows 11 on Unsupported Devices
Older hardware can sometimes trigger installation issues. Here’s how to fix the most common ones.
Error 1: “A media driver your computer needs is missing”
This happens mostly on:
- Intel 11th gen laptops
- Laptops with VMD/RST enabled
Fix: Disable VMD in BIOS
Enter BIOS → Look for:
Storage / SATA Mode / VMD Controller / RST
Set to:
Save & reboot.
Error 2: “Secure Boot must be enabled”
If you still get this error:
Fix 1: Enable UEFI Mode
Go to BIOS:
Boot → UEFI Mode
Fix 2: Disable Secure Boot
If your hardware doesn’t support it, turn it off completely.

- Try a different USB port
- Recreate USB using Rufus
Error 4: Stuck at “Checking for updates”
Skip internet setup using Rufus’s bypass if needed.
After Installation: Optimize Windows 11 for Unsupported Devices
Once Windows 11 is installed, you must optimize it properly so it runs smoothly on older hardware.
1. Disable Heavy Startup Apps
Go to:
Task Manager → Startup apps
Disable:
- Discord
- Steam
- OneDrive
- Adobe
- Spotify
This improves boot time dramatically.
2. Turn Off Unnecessary Animations
Go to:
System → Advanced Settings → Performance → Adjust for best performance
This helps older CPUs and GPUs.
3. Enable High Performance Power Plan
Go to:
Control Panel → Power Options → High Performance
4. Update Drivers Manually
For older devices, Windows Update may not detect all drivers.
Search your model → install:
- Chipset driver
- GPU driver
- Audio driver
- LAN/WiFi driver
5. Keep At Least 20GB Free Storage
Windows performs poorly on old HDDs with low storage.
6. Disable Background Apps
Go to:
Settings → Apps → Installed Apps → disable background permissions.
7. Use Lightweight Antivirus
If your PC is old, avoid heavy antivirus programs.
Use:
- Windows Defender
or - Malwarebytes Free
Is It Safe to Install Windows 11 on Unsupported Devices?

Windows 11 will function normally and handle daily tasks smoothly.
2. You may see a watermark
“System requirements not met” harmless.
3. You may not receive every major update
But security updates usually work fine.
4. Your stability depends on your hardware
A device with:
✔ 8GB RAM
✔ SSD
✔ Decent CPU
runs Windows 11 very smoothly even if unsupported.
Very old devices may struggle.
