Regarding the computer, security should always be a major goal. By 2018, this goal seemed almost overwhelming, in part because of the fact that the famous security vulnerabilities of Specter and Meltdown have affected many users and industries. And let's not forget the CEO of Intel, Brian Krzanich, during his speech at CES, where he did not waste time to solve the problem, as well as the commitment of the Company to solve it for its processors.
During the year, we were all wondering whether future patches could cripple system performance, but fortunately, notable successes seem to predominate primarily in the business. However, there is still degradation for us ordinary people, using older processors, and for this reason, some might welcome the new Specter v2 Windows problem corrector, "Retpoline".
We talked about Retpoline for the first time last October, while we expected the first major release of Windows in 2019 to introduce it. Ideally, it would have been great to see it included in the October update from last year, but this one was fed up with its own problems to deal with. Fortunately, Microsoft has decided to release the update. now instead of waiting for its next update in April. You can currently see the update in Windows Update, noted KB4482887 (as shown in the photo below).
It will take some time for those who know what they are doing to offer performance comparison test results regarding the before and after effects of Retpoline. However, given the fact that the feature is not set aside for the 19H1 version, it seems likely that the potential side effects are minimal. After a few quick updates on our own machines, no difference was found – in the end, a good sign.
Originally developed by Google, Reptonline has made its way into many different distributions of Linux, but Windows users have obviously had to wait a bit. As important as servers are, they tend to do more focused work than desktops. Therefore, the tests performed do not necessarily give us a complete description of the consumer material, hence the importance of additional beta tests (internal and external).
It is important to note that this fix will not affect new processors. Microsoft itself claims that only Intel Broadwell and earlier chips will be affected, while the most recent versions already have a firmware in place to remove the need for this fix. In the end, it is the old hardware users who need all the performance offered by their outdated systems. If you are using an older chip, you definitely want to download this hotfix.
