What Does CloudRadial Check for Windows 11 Readiness?

Overview

This article explains exactly what the CloudRadial agent checks when evaluating whether a device is ready to install Windows 11. Understanding these checks can help you troubleshoot devices that show as not ready even when you believe they meet the requirements.

Checks Performed

CloudRadial performs the following checks to determine Windows 11 readiness:

Memory Check

  • Verifies the device has at least 4 GB of RAM
  • Passes if memory is greater than 4,000,000,000 bytes (4 GB)

CPU Generation Check

  • Checks whether the processor is 8th generation or newer
  • For Intel processors (i3, i5, i7, i9): looks for "-8", "-9", or "-1" in the CPU model string
  • For non-Intel processors: defaults to passing this check and relies on TPM verification instead

Processor Core Check

  • Verifies the device has two or more processor cores
  • Passes if processor count is 2 or greater

64-bit Architecture Check

  • Confirms the operating system is 64-bit
  • Passes if the system is 64-bit enabled

TPM Version Check

  • Verifies that TPM version 2.0 is present
  • Checks if the TPM version string contains "2.0"
  • If TPM version is not available or cannot be read, the result is marked as "Unknown"

UEFI Secure Boot Check

  • Confirms that UEFI Secure Boot is enabled
  • Passes if UEFISecureBoot is true
  • If TPM version is not available, this check is skipped

DirectX 12 Compatibility Check

  • Automatically passes if Windows 11 is already installed
  • Automatically passes if Windows 10 is detected (assumes DirectX 12 compatibility)
  • Marked as "Unknown" for other operating systems

What CloudRadial Does NOT Check

  • Disk space - CloudRadial does not check available disk space as part of Windows 11 readiness. If a device passes all other checks, it will show as ready regardless of available storage.

Common Issues

  • Device shows as not ready despite meeting requirements - Verify the TPM is enabled in BIOS/UEFI and that Secure Boot is turned on. These are the most common reasons a device fails the check.
  • TPM version shows as "Unknown" - The agent was unable to read the TPM version. Check that the TPM chip is enabled in the device firmware settings.
  • Intel CPU not recognized as 8th gen or newer - Confirm the CPU model string contains the expected generation suffix ("-8", "-9", or "-10"/"-11"/"-12" etc. which all contain "-1").
