“Standard hardware security not supported” is a Windows Security capability warning, not a malware diagnosis. It means Windows cannot confirm at least one part of its standard hardware-security baseline: TPM 2.0, Secure Boot, Data Execution Prevention (DEP), or the UEFI Memory Attributes Table (UEFI MAT). A computer can show TPM 2.0 and Secure Boot as enabled and still fail the complete check because of virtualization, firmware, a driver, or one of the other requirements.
Use Windows Security and msinfo32 to identify what Windows is not recognizing, then update drivers and firmware before changing security settings. Do not clear the TPM until you have backed up important data and prepared for possible BitLocker recovery.

What the message means
In Windows Security, the Device security page evaluates whether the computer can provide a defined set of hardware-backed protections. Microsoft describes the status this way: “Standard hardware security not supported. This means that your device does not meet at least one of the requirements of standard hardware security.”
The wording is important. Windows is reporting a missing capability or an unverified state; it is not saying that an application has compromised the computer. The warning can appear on a perfectly usable, malware-free PC whose firmware, drivers, or configuration do not satisfy the entire baseline.

The four standard requirements
- TPM 2.0: a Trusted Platform Module, either a discrete chip or firmware-based implementation supplied by the platform.
- Secure Boot: UEFI verification of boot components before Windows loads.
- Data Execution Prevention (DEP): a protection that prevents code from executing in memory regions intended for data.
- UEFI Memory Attributes Table (UEFI MAT): a firmware-provided description that lets Windows apply suitable memory protections.
These are a set. Passing three does not produce a “supported” result if the fourth is absent or cannot be verified.
Standard versus enhanced hardware security
Windows also distinguishes an enhanced level. Enhanced hardware security includes all four standard requirements and adds memory integrity, also called Hypervisor-protected Code Integrity (HVCI). Memory integrity uses hardware virtualization. Microsoft states that hardware virtualization must be enabled in the system’s UEFI or BIOS before memory integrity can be used.
| Windows Security level | What Windows expects | What a failure usually indicates |
|---|---|---|
| Standard hardware security | TPM 2.0, Secure Boot, DEP and UEFI MAT | At least one baseline capability is missing, disabled, unsupported or not recognized |
| Enhanced hardware security | Everything in the standard baseline plus memory integrity | Hardware virtualization, a compatible driver or another HVCI prerequisite is unavailable |
Therefore, seeing a problem with memory integrity is not identical to the standard-hardware warning. A machine can satisfy the standard set while failing the enhanced check, or it can fail both.
Why TPM 2.0 and Secure Boot can still show as enabled
TPM and Secure Boot are only two entries in the four-part standard requirement. DEP can be disabled or altered by a system configuration, and UEFI MAT depends on firmware support rather than a normal Windows switch. A BIOS revision can also expose a feature incorrectly, while an incompatible driver can prevent Windows from enabling related virtualization-based protections.
Virtualization is especially easy to overlook. It is required for memory integrity, not listed as one of the four standard requirements themselves. If you are trying to reach enhanced protection, check virtualization even after TPM and Secure Boot pass.
Microsoft Q&A guidance also identifies outdated drivers and BIOS firmware as common explanations. That is why checking only the two visible green-looking entries in Device security can lead to a dead end.
Check exactly what Windows recognizes
1. Inspect Device security
- Open Windows Security from the Start menu.
- Select Device security.
- Open Security processor, Secure boot and Core isolation, one at a time.
- Record whether each panel is present, enabled, or reporting a problem. Expand any warning for its exact wording before changing a setting.
If there is no Security processor entry, Microsoft says the computer may not have the required TPM hardware, or the TPM may be disabled in UEFI. In that case, consult the device or motherboard manufacturer’s support instructions rather than assuming that installing a Windows package will create a TPM.
2. Run System Information
- Press Windows key + R, type
msinfo32, and press Enter. - In System Summary, check BIOS Mode. A modern Secure Boot configuration should report UEFI, not Legacy.
- Check Secure Boot State; the expected enabled state is On.
- Review Virtualization-based Security Services Running. For a fully active virtualization-based configuration, Microsoft Q&A guidance uses Running.
- Review the Device Guard status. The same guidance identifies Running as the active state to look for.
Take a screenshot or write down the values before entering firmware setup. It gives you a reference if a setting changes during troubleshooting.
Fixes, in the safest order
Update Windows and device drivers
Start with the least disruptive changes. Install all available Windows updates, restart, and then open Device Manager to look for devices with warning icons or available driver updates. Microsoft recommends updated drivers from Windows tools or directly from the device manufacturer, particularly when an incompatible driver blocks memory integrity.
Do not remove a driver simply because it appears in a warning list. First look for a newer signed version from the manufacturer. If no compatible release exists, you may have to leave memory integrity off until the hardware is replaced; that affects enhanced protection but does not prove that the PC is infected.
Update UEFI/BIOS and TPM firmware
Check the support page for the exact computer model or motherboard revision. Install only firmware intended for that model, follow the manufacturer’s power and recovery instructions, and keep the machine connected to reliable power. Microsoft notes that a firmware update may resolve TPM problems and can also add or correct security capability reporting.

Enable or verify the TPM in UEFI
Reboot into the firmware setup screen using the key shown by the manufacturer during startup. The setting may be labelled differently across systems, such as a security processor or firmware TPM option. Enable it only when the manufacturer documents the option for your platform, save the change, and boot back into Windows.
If the motherboard has a connector for a discrete TPM module, that does not mean any module will work. The module must be supported by that exact motherboard, and many systems already provide firmware TPM. Buying an incompatible module cannot satisfy Windows and can introduce a separate hardware problem.
Verify Secure Boot and UEFI mode
In UEFI setup, confirm that Secure Boot is enabled and that the system is using UEFI rather than Legacy or Compatibility Support Module mode. If msinfo32 reports Legacy BIOS mode, changing boot mode can require converting the system disk and may make an existing installation unbootable if done incorrectly. Back up first and use the manufacturer’s documented conversion procedure; do not simply toggle firmware options at random.

Scan for outdated or missing drivers - takes under a minuteDriver Scan →Repair Windows errors before they cause bigger problemsFix Now →Check virtualization for memory integrity
If the warning is accompanied by a Core isolation or memory-integrity problem, enable hardware virtualization in UEFI or BIOS. The label may refer to processor virtualization rather than Windows Virtual Machine Platform. Save the setting, boot Windows, and revisit Windows Security > Device security > Core isolation.
Virtualization alone will not repair a blocked driver. If memory integrity still cannot be enabled, return to Device Manager and Windows Update, identify the incompatible driver, and obtain a newer version from the manufacturer.
Do not disable DEP as a workaround
DEP is one of the standard requirements. Avoid boot-configuration changes that turn it off merely to make an old application run. If a legacy program requires an exception, look for an updated application or a vendor-supported compatibility solution. Disabling a baseline protection can remove the capability Windows is trying to verify.

TPM clearing: the step that needs preparation
Clearing the TPM is not a routine refresh button. It removes keys and stored TPM state used by Windows features and applications. Microsoft warns users to back up data before clearing it. If BitLocker or another encryption feature is active, make sure you have the recovery key before doing anything that changes TPM state.

If the warning is simply that one baseline requirement is unsupported, clearing the TPM will not add UEFI MAT, repair a missing driver, or create hardware that the platform does not provide.
When the warning cannot be fixed
Some computers genuinely lack one of the required capabilities. UEFI MAT is supplied by firmware, and TPM support depends on the platform. A physical TPM module is relevant only when the motherboard explicitly supports that model and does not already include firmware TPM. Secure Boot, DEP and virtualization are settings or processor/firmware capabilities, not universal add-on products.
On unsupported hardware, keep Windows updated, use a supported antivirus and account-security configuration, and understand that Windows Security will continue to report the limitation. An optional driver-maintenance service may help locate newer drivers after Windows Update and Device Manager checks, but no driver service can add absent TPM hardware, UEFI MAT support, Secure Boot capability or processor virtualization.
Is the PC compromised?
Not from this message alone. The status says that Windows cannot activate or verify one or more hardware-based protections. Malware findings appear in separate Windows Security areas, such as virus and threat protection, and require separate evidence. Treat the warning as a configuration or compatibility investigation: identify the missing requirement, update software and firmware, and avoid destructive TPM actions until your recovery information is safe.
