SpecuCheck is a command line utility that checks to see if your machine is vulnerable to attack from Spectre and Meltdown.

It works by utilizing two new information classes that were added to the NtQuerySystemInformation API call as part of the recent patches introduced in January 2018 and reports the data as seen by the Windows Kernel.

SpecuCheck provides you with details about whether or not any patching has been administered on your machine correctly. Even though it is a command line utility, it should not scare off novice users as it is straightforward to deploy.

To run SpecuCheck, simply execute it on the command-line:

c:SpecuCheck.exe

The above will result in an informational screen indicating which features/mitigations are enabled

If you see the text: Your system either does not have the appropriate patch, or it may not support the information class required, this indicates that your system is not currently patched to mitigate against these vulnerabilities.
