在「配置管理器」中设置为Debug/x64,编译生成项目发现如下错误: Visual Studio默认开启了缓解 Spectre 攻击的机制,可在 VS 安装器中选择安装指定的支持库,我们实验环境下可以直接关闭该功能,在项目属性-C/C++-代码生成-Spectre Mitigation设置为Disable: 随后便可以成功编译,在[src]/x64/Debug/下,可以看到生成的二...
To enable multiple mitigations, you must add the REG_DWORD value of each mitigation together. For example: Mitigation for Transaction Asynchronous Abort vulnerability, Microarchitectural Data Sampling, Spectre, Meltdown, MMIO, Speculative Stor...
Windows Support unleashed a new web page on Friday, January 26 to explain its actions. It’s entitled “Update to Disable Mitigation against Spectre, Variant 2.” The specific vulnerability involved is CVE 2017-5715 (requires microcode update for full enablement). However, t...
Installing WDK no longer enables Spectre mitigations for all C++ projects as seen in WDK 1903 While the WDK install will enable Spectre mitigation by default for all drivers, it no longer enables them for all C++ projects. Error ‘A WDK corresponding to target ’10.0.19041.0’ was not found...
One of the great worries about the Meltdown and Spectre CPU flaws -- aside from attackers exploiting them -- has been that mitigations for the attacks could have a severe impact on performance, ranging between five and 30 percent. That concern was greatest for Intel's microcode mitigations...

Some processors and apps are more/less affected by the Spectre and Meltdown mitigations. If your server's efficiency drops by 30 percent, it is somehow a big deal. Best thing is to benchmark your apps/games with mitigations OFF and ON. Usually, it shouldn't make much a differenc...
Upgrade Readiness has added the ability to assess Spectre and Meltdown protections on your devices. This addition allows you to see if your devices have Windows OS and firmware updates with Spectre and Meltdown mitigations installed, as well as whether your antivirus client is compatible with the...
