Microsoft tool incorrectly reports “This PC can’t run Windows 11” error

This PC can't run Windows 11 error

A number of users are seeing “This PC can’t run Windows
11
” error when running compatibility checks using
Microsoft’s PC Health Check Tool. It looks as though
Microsoft’s misconfigured Health Check Tool is at the heart of
sporadic problems some people have encountered.

Ahead of the wider rollout, Microsoft has released a new app
called “PC Health
Check” to help users run compatibility tests on Windows 10
and prepare their device for the big upgrade.

There seems to be some confusion around this app and some
people are reporting “This PC can’t run Windows
11
” errors. A lot of users have reported problems when
running compatibility tests with PC Health Check Tool, usually
because of TPM 2.0 requirement and problems with existing
software or hardware.

Windows 11 is designed to work on all modern hardware, but
it appears that the PC Health Check Tool is using a pair of
switches that incorrectly returns the compatibility test result
as “This PC can’t run Windows 11” even when the device is
actually supported.

“While this PC doesn’t meet the system requirements to run
Windows 11, you’ll keep getting Windows 10 updates,” the error
message reads.

This PC can't run Windows 11

Technically, nearly all modern Windows 10 PCs are eligible for
Windows 11 upgrade.

The minimum system requirements of Windows 11 isn’t
straightforward and Microsoft’s documentation is particularly
confusing.

According to the document, TPM 1.2 or newer
is now a minimum system requirement, while TPM 2.0 is the
recommended system requirement.

For those unaware, TPM (Trusted Platform Module) is a security
feature built into all modern PCs and it enables new defences
on a hardware level. According to Microsoft officials, almost
every CPU in the last 5-7 years has a TPM. On Intel PCs, it is
called “Intel PTT”. For AMD, it would be “AMD PSP fTPM”.

“TPMs have been required for OEM certification since at least
2015 and was announced in 2013,” Microsoft said.

The false error message is reported because there are two
floors of requirements for Windows 11. While the second floor
requires newer processors (8th-gen, Ryzen 2000+), the first or
hard floor allows anyone to install Windows 11 if they meet the
following requirements:

  • CPU with two cores and a minimum clock speed of 1 GHz
  • RAM: 4 GB
  • Storage: 64 GB
  • Security: TPM Version >= 1.2
  • SecureBootCapable = True

In other words, nearly all modern CPUs in the market are
compatible with Windows 11.

Why am I getting “This PC can’t run Windows 11”? error

The PC Health Check app is apparently checking your device’s
compatibility against the recommended or second-floor hardware
requirements, which requires 8th Gen Intel & Ryzen 2000 series
processors and TPM 2.0.

However, in reality, you can install Windows 11 if you meet the
minimum system requirements, which is 64-bit dual-core
processors with 1 GHz clock speed and TPM 1.2.

Microsoft confirms “This PC can’t run Windows 11” error

Thankfully, Microsoft is aware of the reports and is working on
a fix.

A company representative confirmed that Windows 11 Health Check
app will be updated in the coming weeks with more clarity on
system requirements; hard and soft floors.

“We’re going to improve the PC Health Check app over the next
couple of week,” the company said.

Windows 11 preview builds are planned for next week and
Microsoft is hoping to address some of these issues later this
week.

TPM requirements

Windows 11 is designed for everyone and it’s compatible with
modern hardware, so naturally, it will run smoothly on PCs
shipped in the last few years, but it can be installed on older
hardware too.

Regarding the TPM requirement, Microsoft officials explained
that PCs shipped in the last few years come with the TPM 2.0
feature. It’s possible that your PC does have TPM, but
it’s disabled in the BIOS. If it’s disabled, you need to get
into the BIOS and turn on TPM manually and reboot the system.

You can check if your device has the compatible TPM by running
the command get-tpm in PowerShell:

TPM check

Microsoft is also believed to be working on features that will
help you diagnose problems installing Windows 11 updates on PCs
that are already running Windows 10.

If we’re being honest you probably don’t need to rush to get in
on this. Windows 11 is still in preview and it is currently
projected to go live in the fall, so we have enough time to
prepare our devices for the upgrade.

Also, remember that Windows 11 is still Windows and you’ll be
able to bypass the TPM requirements unofficially.
