Gibson warns that his tool is new and that conclusions on the output of the tool should be carefully considered as he writes, “it has been carefully tested under as many different scenarios as possible. This InSpectre utility was designed to clarify every system's current situation so that appropriate measures can be taken to update the system's hardware and software for maximum security and performance. But older processors, lacking these newer features, will be significantly burdened and system performance will suffer under some workloads. To further complicate matters, newer processors contain features to minimize the performance impact of these important security improvements. Protection from these two significant vulnerabilities requires updates to every system's hardware–its BIOS which reloads updated processor firmware–and its operating system–to use the new processor features. The industry quickly responded, and is responding, to these Meltdown and Spectre threats by updating operating systems, motherboard BIOSes and CPU firmware. In early 2018 the PC industry was rocked by the revelation that common processor design features, widely used to increase the performance of modern PCs, could be abused to create critical security vulnerabilities.

The tool also makes it possible to enable or disable protection against Spectre and Meltdown.

InSpectre shows which updates have been installed and what has to be done to protect the system against the attacks. This can have a negative impact on performance, depending on the tasks performed on the computer. To fully protect against both attacks, users have to update both their BIOS and operating system. This application is made by security researcher Steve Gibson. This freeware download offers you the Free inSpectre, this tool tool checks Windows computers for Meltdown and Spectre vulnerabilities. Besides checking whether the system is vulnerable to the Spectre and Meltdown attack, the tool also checks whether performance of the computer has been decreased.
