Microsoft is testing it Retpoline, μια νέα μέθοδο επιδιόρθωσης ττου Specter 2 από την Google, στα Windows 10 Insider Builds εδώ και αρκετό καιρό. Όπως φαίνεται η εταιρεία πρόσθεσε το Retpoline στα Windows 10 της έκδοσης 1809 με την αθροιστική ενημέρωση KB4482887 της 1ης Μαρτίου.
Retpoline promises improved performance compared to the previous fix method used by Microsoft in its operating systems.
According to the company that tested the performance of Windows 10 systems, Retpoline improved the Office application start time by about 25%.
Η technology Retpoline is not enabled by default even though it is included in the March 1st update. Microsoft plans to implement it in the coming months.
However, if you do not want to wait, we'll see below how you can immediately activate Retpoline, provided you run Windows 10 in the 1809 version and have installed the latest cumulative update.
Of course before any changes to your system it is recommended to create backups security.
