InSpectre（漏洞Spectre和Meltdown的检测和开关工具）

“InSpectre” is an easy to use & understand utility designed to clarify

the many overlapping and confusing aspects of any Windows

system's ability to prevent the Meltdown and Spectre attacks.

As the application's textual display says...

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 industry quickly responded, and is responding, to these Meltdown and Spectre threats by updating operating systems, motherboard BIOSes and CPU firmware.

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. To further complicate matters, newer processors contain features to minimize the performance impact of these important security improvements. But older processors, lacking these newer features, will be significantly burdened and system performance will suffer under some workloads.

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.

“InSpectre”是一个易于使用和理解的实用工具，旨在帮助Windows系统在防止来自Meltdown 和Spectre方面的攻击。

正如应用程序的文本显示所说……

在2018年初，个人电脑行业被揭露出来的事实震惊了:通用处理器的设计特性，被广泛用于提高现代个人电脑的性能，可能被滥用来制造关键的安全漏洞。该行业迅速做出回应，通过更新操作系统、主板和CPU固件来应对这些Meltdown 和Spectre的威胁。

保护这两个重要的漏洞需要更新每个系统的硬件——它的BIOS重新加载更新的处理器固件和它的操作系统——使用新的处理器特性。为了使问题更加复杂，新的处理器包含一些特性，以最小化这些重要安全改进的性能影响。但是，缺少这些新特性的老处理器将会有很大的负担，系统性能也会受到一些工作负载的影响。

这个InSpectre软件旨在澄清每个系统的当前情况，以便采取适当的措施来更新系统的硬件和软件以获得最大的安全性和性能。

历史版本：

Release #1 — Initial release:

The first release was triggering false-positive warnings from 3rd-party anti-virus scanners. This was probably due to a registry key the application uses to enable/disable the Meltdown and Spectre protections. Also, the language used in one of the text-explainers was confusing and self-contradictory.

Release #2 — Second try:

This second release hides its use of the registry key that was upsetting so many anti-virus scanners. A pass through Virus Total shows that made a huge difference. And that confusing paragraph was rewritten into two, which are now presented more correctly. Let's see how this second try fares.

Release #3 — Raw Technical Data Display:

InSpectre's more technically inclined users have asked for more information about how InSpectre makes its decisions. Non-Windows users have also asked for that information so that InSpector could be run on Linux and MacOS machines (under WINE) to check the non-Windows machine's CPU support. As shown to the right, InSpectre release #3 adds a “Show Technical Details” item in the system control menu at the upper-left corner of the app. Click on the little “Spectre” icon and select the “Show Tech Details” item to display the raw data obtained by InSpector's analysis of its operating environment.

Release #4 — Silent System Probe Option:

When InSpectre is launched with the string “probe” in its command line, its Windows user interface will be suppressed. The application will assess its hosting system's status, then immediately terminate itself returning a decimal exitcode which encodes eight “trouble bits” itemizing trouble. Therefore, an exitcode of zero (0) is returned only by a fully secure system.

这个软件怎么用？

最直白的，让你看到哪个漏洞修补了，哪个没修补，系统性能会不会受到补丁影响。

如上图，病毒爆发后我打了微软撤回的那个补丁，NO表示我不受Meltdown影响，Yes表示我受Spectre影响，Good表示我的性能不受影响

其次，注意图中下方的Disable，它允许你性能收到影响时通过禁用补丁，使你电脑性能提高，注意这个操作需要重启后才生效。

在标题栏上右键，还可以查看一些技术细节，当然我这种小白是看不懂的。
