System Requirements for Windows 11

Checking your PC’s compatibility

Before diving into the installation process, it’s crucial to determine if your PC can run Windows 11. Microsoft provides an official PC Health Check app, which quickly assesses your system’s compatibility. However, for older PCs, this tool may not always provide accurate results.

Minimum hardware specifications

To run Windows 11, your PC should meet the following minimum requirements:

• Processor: 1 gigahertz (GHz) or faster with 2 or more cores
• RAM: 4 GB or more
• Storage: 64 GB or larger storage device
• System firmware: UEFI, Secure Boot capable
• Graphics card: DirectX 12 compatible or later with WDDM 2.0 driver
• Display: High definition (720p) display, 9″ or greater monitor, 8 bits per color channel

Component	Minimum Requirement
Processor	1 GHz, 2+ cores
RAM	4 GB
Storage	64 GB
Graphics	DirectX 12, WDDM 2.0
Display	720p, 9″ or greater

TPM 2.0 requirement explained

Trusted Platform Module (TPM) 2.0 is a security feature that Microsoft requires for Windows 11. It’s a microchip that provides hardware-based security functions. Many older PCs don’t have TPM 2.0, which can be a significant barrier to installation. However, there are ways to bypass this requirement, which we’ll explore in the next section.

Now that we understand the system requirements, let’s move on to downloading the Windows 11 ISO file.

Downloading Windows 11 ISO

A. Locating the official Microsoft download page

To begin your Windows 11 installation journey, you’ll need to find the official Microsoft download page. Follow these steps:

1. Open your preferred web browser
2. Go to the Microsoft Windows 11 download page
3. Scroll down to the “Download Windows 11 Disk Image (ISO)” section

It’s crucial to use the official Microsoft source to ensure you’re getting a genuine, malware-free copy of Windows 11.

B. Choosing the correct version

Once on the download page, you’ll need to select the appropriate version for your PC:

Option	Description
Windows 11	Standard version for most users
Windows 11 (multi-edition ISO)	Includes Home, Pro, and Education editions

Select your preferred language from the dropdown menu and click “Confirm.” Then, choose the 64-bit Download option, as most modern PCs use 64-bit architecture.

C. Creating bootable USB drive

After downloading the ISO, you’ll need to create a bootable USB drive:

1. Insert a USB drive (at least 8GB) into your PC
2. Download and install the official Microsoft Media Creation Tool
3. Run the tool and select “Create installation media for another PC”
4. Choose your language, edition, and architecture
5. Select “USB flash drive” as your media
6. Follow the prompts to complete the process

With your bootable USB drive ready, you’re now prepared to move on to the installation process. Next, we’ll explore how to bypass TPM and CPU restrictions to install Windows 11 on older PCs.

Bypassing TPM and CPU Restrictions

Using the Windows 11 Registry Hack

To bypass TPM and CPU restrictions, you can use a simple registry hack. This method involves editing the Windows registry to trick the installer into thinking your PC meets the requirements.

1. Press Win + R, type “regedit,” and hit Enter
2. Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup
3. Right-click, select New ＞ DWORD (32-bit) Value
4. Name it “AllowUpgradesWithUnsupportedTPMOrCPU”
5. Double-click and set the value to 1

Pros	Cons
Simple to implement	May not work in future updates
No file modifications	Potential security risks
Reversible	May affect system stability

Modifying installation files

Another method involves modifying the Windows 11 installation files directly. This approach requires more technical skill but can be more effective.

1. Mount the Windows 11 ISO
2. Locate and open the “sources” folder
3. Find “appraiserres.dll” and rename it to “appraiserres.dll.old”
4. Create a new, empty file named “appraiserres.dll”

This trick fools the installer into skipping the hardware check altogether.

Risks and considerations

While these methods can help you install Windows 11 on older PCs, they come with potential risks:

• Reduced security due to bypassed TPM requirements
• Possible instability or performance issues
• Risk of losing support or updates from Microsoft

Consider these factors carefully before proceeding with the installation. Now that we’ve covered bypassing restrictions, let’s move on to the actual installation process.

Installation Process

Booting from USB drive

To begin the Windows 11 installation process, you’ll need to boot your PC from the USB drive containing the Windows 11 ISO. Here’s how:

1. Insert the USB drive into your PC
2. Restart your computer
3. Press the boot menu key (usually F12, F11, or Esc)
4. Select the USB drive from the boot menu

Common Boot Menu Keys
F12 (most common)
F11
Esc
F10
F8

Step-by-step installation guide

Once you’ve successfully booted from the USB drive, follow these steps:

1. Choose your language and keyboard layout
2. Click “Install Now”
3. Enter your product key or select “I don’t have a product key”
4. Select the edition of Windows 11 you want to install
5. Accept the license terms
6. Choose “Custom: Install Windows only (advanced)”
7. Select the drive or partition for installation
8. Wait for the installation to complete

Troubleshooting common issues

If you encounter problems during installation, try these solutions:

• Error 0xC1900101: Disconnect unnecessary peripherals
• “This PC can’t run Windows 11”: Use the Media Creation Tool
• “TPM 2.0 is required”: Follow the TPM bypass method from earlier
• Installation freezes: Check for faulty RAM or update BIOS

Preserving your files and settings

To keep your files and settings during installation:

1. Choose “Upgrade” instead of “Custom” installation
2. Select “Keep personal files and apps” when prompted
