InSpectre is a fast way to check if your machine is susceptible to the Spectre and Meltdown vulnerabilities. Video tutorial available.

It is portable and does not require an Internet connection to function. What InSpectre does is check for any Spectre and Meltdown patches on your system and then provides you with the potential impact on performance. Additionally, it will allow admins the option to disable the respective protections if needed - keep in mind, using this to enable or disable those protections will modify the Registry keys.

Within the main window, InSpectre provides you with detailed data regarding the checks that it made and also provides you with a decent amount of general vulnerability information about each of the vulnerabilities. You are given information that pertains specifically to whether your OS or hardware need updating to protect against attacks that may attempt to exploit the weaknesses that Spectre or Meltdown pose. The impact rating is unique among some of the other similar tools but knowing if it is an accurate assessment is yet to be seen. But still a neat function for performance concerned users.

This utility (as are all apps featured on MajorGeeks) is provided to you exactly as the author intended it to be with no additions or changes.
