How to fix Windows 11 Installation Problems

Authored by: Support.com Tech Pro Team

1. Introduction

In this guide, you will learn how to Identify and Fix Windows 11 installation problems and Errors.

2. Identify and fix using Built-in Troubleshooter

If you're encountering problems installing Windows 11 via Windows 10's update tool, don't panic. Windows 10 has a built-in troubleshooter that can help identify any problems. This can also reset the Windows Update app, which can help kickstart the installation.

To do this,

1. Click the Start menu

2. Click the cog icon on the left, which will open up the Settings window

3. Click ‘Update & Security

4.  Click on ‘Troubleshoot’

5. Click on Additional Troubleshooters

4. Click on ‘Windows Update’ then ‘Run the troubleshooter’ and follow the instructions

5. Click Apply this fix if the troubleshooter finds a solution

3. Check the Windows 11 system requirements

To install Windows 11, or to ensure that it runs correctly, you'll need to make sure that your PC matches the following Windows 11 minimum system requirements:

• Processor: 1 gigahertz (GHz) or faster with at least two cores on a compatible 64-bit processor or SoC
• RAM: 4GB
• Storage: 64GB
• System Firmware: UEFI, Secure Boot capable
• TPM: Trusted Platform Module 2.0
• Graphics Card: DirectX 12 or later with WDDM 2.0 driver
• Display: 720p, 8-bit per color channel, at least 9-inch diagonal
• Internet Connection and Microsoft Account: Windows 11 Home requires an active internet connection and a Microsoft Account to complete initial, first-use setup of the operating system, or when switching a device out of Windows 11 Home in S-mode.

For a complete list of additional, non-essential requirements, check out Microsoft's Windows 11 specification page.

These are the minimum specs required for running Windows 11, but for the best Windows 11 experience, we recommend you install it on a device that's more powerful. The 4GB RAM requirement is especially low – we wouldn't recommend trying to run Windows 11 on anything with less than 8GB of RAM.

4. Windows 11 compatibility check

In case your system meets the above-mentioned criteria, you need to run a health check to keep your system ready to install Windows 11 

• To run the health check you need to first download and install Microsoft's PC Health Check app
  
  
• Once installed, run the program
  
  
• Click on the blue coloured “Check Now” button on the Windows 11 banner
  
  
• If your system is compatible, you’ll get a pop-up stating “This PC will run Windows 11"

5. Windows 11 won't run due to TPM

In case Microsoft's Windows 11 upgrade checker tells you that your PC isn't supported but it meets all the other requirements then you need to check your BIOS to enable TPM 

Almost every modern CPU comes with TPM support. In case you have an Intel CPU then you need to switch to TPM and for AMD you need to check PSP fTPM in the BIOS. Once done, you can run Microsoft's health checker app to confirm the status. This should allow Windows 11 to install

You can check the status of TPM support in your PC by doing the following:

1. Press Windows key + R

2. When the box appears, type tpm.msc to open the Trusted Platform Module Management window

3. Look for a sub-window titled TPM Manufacturer Information and check under Specification Version to see what TPM version your device has

6. Revert Back

If you're experiencing issues after upgrading to Windows 11 and your device does not meet the minimum system requirements, we recommend you go back to Windows 10

• Select Start > Settings > System > Recovery > Go back.
