Retpoline ger Spectre V2 skydd med mycket bättre prestanda!

@the squonk: Najs! blir att testa till helgen.

Funkar inte för mig.
Jag körde registerhacket.
Nycklarna finns i registret.
KB4482887 är installerad.
Verkar som jag ändå inte har Retpoline.

Så här ser det ut för mig.

Körde samma, ser ut att ha tagit skruv.

Inbillar mig också att datorn är lite rappare nu

Slagit på det och verifierat att det är på, märker ingen skillnad än så länge. Testade starta word innan och efter, ungefär samma uppstartstid.

Något fel på mitt Windows, skit samma, det fixar sig kanske till våruppdateringen.

Hur ser det i i ert register?
