Microsoft Defender Bug Could Be Causing Windows 11 to Miss TPM Support on Devices

Microsoft Defender problems are now seemingly causing TPM 2.0 detection problems in Windows 11 following Patch Tuesday.


Earlier this month, rolled out March 2023 Patch Tuesday. As always, the monthly release brought its own share of bugs and issues. One of them is a Local Security Authority (LSA) flaw in Microsoft Defender, which I reported on this week. It now seems that the LSA Defender bug is causing wider issues on .

Specifically, users are reporting that another bug is in where the app is surfacing the message “There is no TPM available” under processor details. What is interesting is this message is shown despite the device having TPM 2.0.

If you are unfamiliar, TPM is a requirement to install and receive updates for Windows 11. If a device does not have TPM 2.0, it cannot officially have Windows 11. So, this message is problematic for users as it essentially tells users their compatible device is not compatible with Windows 11.

When seeing this message, users can confirm the problem by heading to “Security devices” through “tpm.msc” inside Device Manager.

Windows Defender Problem

Windows Defender has had a similar problem in recent weeks. a bug that displays the message “Standard hardware security not supported” even on fully compatible machines.

Microsoft explains the recent March 2023 Patch Tuesday update for is broken and causing another problem. The company has added a workaround for the issue. Microsoft points out the update KB5007651 (version 1.0.2302.21002) is showing the message “Local Security protection is off”.

That “Standard hardware” but does not have a workaround, but this latest KB5007651 flaw does. When the message is displayed, users face persistent prompts to restart their device. If they give in and restart, the message continues.

Tip of the day: When using your Windows 10 laptop or convertible with a mobile hotspot you might want to limit the Internet bandwidth your PC uses. In our tutorial we are showing you how to set up a metered connection in Windows 11 or Windows 10 and how to turn it off again, if needed.
