Strong Protections for Spectre and Meltdown

In the latest version of Windows 10 update, there are some robust protections for Spectre and Meltdown. In the past, Microsoft has attempted to patch these vulnerabilities but they had resulted in performance problems. While, in Windows 10 May 2019 Update, everything will get better.

Retpoline Will Be Used to Improve Windows 10 Performance. This should finally fix the performance issues and it can also deliver some strong protections for vulnerabilities.

According to Microsoft, Retpoline is described as a performance optimization for Spectre Variant 2. This new technique can highly improve the performance of Spectre variant 2 mitigations to noise-level for most scenarios, said by the software maker.

Previously, the patches for the vulnerabilities were using the capabilities exposed by CPU microcode updates. It’s a fact that this could fix the security issue. But many users discovered that their computer performance was degraded, and this always happened on the old machines.

Now, the usage of Retpoline on Windows has reportedly improved the performance of the mitigations. For example, when you launch the OFFICE app, the startup speed is 25% faster.

When you update your Windows to Windows 10 May 2019 Update, the slowdown issue caused by patch for the vulnerabilities will be expectedly largely disappeared or unnoticeable.

The test buildings have been tested by Insiders, and during the process, Microsoft has noticed that there are some measurable improvements in Start reliability. For instance, Start can be open faster and work smoothly when the main Shell is busy.

Moreover, these two changes may not significantly impact the performance of high-end computers. They can still offer better performance on the mid-core or low-end machines.

Windows 10 May 2019 Update is ready for update. It will be released later in this month and at that time you can experience these new Windows 10 19H1 performance improvements.
