Microsoft Windows 11 has been out for a couple of weeks.

You may want to determine if your computer can run the new OS.


WhyNotWin11 is an application that does a pretty job at looking at your computer’s hardware and identifying where it lags in being able to install Microsoft Windows 11.



WhyNotWin11 is available at:-



Releases are available at https://github.com/rcmaehl/WhyNotWin11/releases/ ( Link ).



Please access the Assets section to review the binaries.



  1. 64-bit
    • WhyNotWin11.exe
  2. 32-bit
    • WhyNotWin11_x86.exe


Based on your OS bitness, please download the corresponding artifacts.

That is, if your OS is 64 bit, please reach for WhyNotWin11.exe.

If your OS is 32 bit, please reach for WhyNotWin11_x86.exe.



Once downloaded, please run the downloaded file.


Area Target Description Impact
Architecture 64-Bit CPU
64-Bit OS
Hardware Bitness
OS Bitness
If the CPU is not 64-bit, then the hardware ( Motherboard ) needs to be upgraded.
If OS is not 64-bit, the current 32-bit needs to be wiped out, and completely re-installed with a 64-bit installation media.
Boot Method UEFI A Method your motherboard uses to load Windows. Legacy results can be fixed on newer motherboards in your BIOS/UEFI Settings
CPU Compatibility A “compatible” 1 GHz or faster dual-core 64-bit processor from Intel, AMD, or Qualcomm. On desktops, CPUs via motherboards replacements can sometimes be changed.
On Laptops, it is likely impossible to change the CPUs
CPU Core Count The number of CPUs and the number of Cores On desktop, requires physical replacement.
On laptops, it is not replaceable.
CPU Frequency The CPU’s speed On desktop, requires physical replacement.
On laptops, it is not replaceable.
Disk Partition Type GPT Computer disks have to be partitioned prior to use.  Partition options available in MS Windows include legacy options such as MBR and newer options such as GPT. Non GPT Partition can be remediated by using tools such as Microsoft’s MBR2GPT Tool.
CPU Frequency The CPU’s speed On desktop, requires physical replacement.
On laptops, it is not replaceable.
RAM Installed 4 GB of RAM The memory size On desktops, memory can be added to a max level based set by the hardware & bios.
On high-end laptops, memory can be added to a max based on the laptop’s motherboard.
Secure Boot UEFI Secure Boot supported and enabled The method your motherboard uses to load MS-Windows On newer desktops and laptops, Secure Boot can be enabled
Storage available 64 GB of Storage Hardrive Size On desktops and high-end laptops, hard drives can be replaced.
TPM Version TPM v2.0 A Security module used by MS-Windows All modern AMDs CPUs contain TPM 2. Some modern Intels, contain TPM 2, as well

How To

Some of the settings listed above require you to access your BIOS.

Here are the pathways for accessing your BIOS and finding the settings.

How to upgrade to Windows 11, whether your PC is supported or not


How do I get into my PC’s BIOS?

Usually, you can enter your BIOS by pressing some key after turning on your PC but before Windows begins to boot. The key varies, but common ones include the Delete key, F2 (for Dell systems), F1 (for Lenovo systems), or F10 (for HP systems).

The consistent but more roundabout way of opening your BIOS is to go to the Windows Settings app, then Windows Update, then Recovery, and then Restart Now under “Advanced startup.” In the basic blue screen you see next, click Troubleshoot, then Advanced Options, then UEFI Firmware Settings.

How do I enable my TPM?

Enabling your processor’s built-in firmware TPM is easy, but finding the setting to do it sometimes isn’t. If you’re not sure what you’re doing, try searching for “[manufacturer of your computer or motherboard] enable TPM,” because many manufacturers have created help pages specifically because of Windows 11.

For Intel systems, if you can’t find a setting marked “TPM” somewhere in the chipset or security settings, look for “Platform Trust Technology” or “PTT” and enable that. AMD systems usually just refer to it as an “fTPM,” though you may also see it called the “Platform Security Processor,” or “PSP.”

Once you’ve enabled your TPM, reboot into Windows and use the Health Check app to make sure it’s working properly.

How do I enable Secure Boot?

Any computer made since Windows 8 was released in 2012 ought to support Secure Boot, which helps prevent unsigned and potentially malicious software from being loaded during your PC’s boot process. You should be able to turn it on in your PC’s BIOS if it isn’t already enabled, usually either in a “Security” or “Boot” section. As with enabling your TPM, if you can’t find the setting, check your PC’s or motherboard’s manual.


WhyNotWin11 does a very good job at determining your computer’s readiness to run Microsoft Windows 11.
