只需要微軟作業系統和軟體更新的V1/V3都還好,
嚴重的是V2的CPU微碼更新,會劇烈的降低效能,
即使是最新的CPU也是一樣。
如果電腦不上網不存帳密不裝不明程式無個人隱私只玩單機遊戲,
安裝更新後可以在Registry設定管理原則,
把V2/V3的補丁從作業系統停用。
非常不建議這樣做。
啟用緩解
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverride /t REG_DWORD /d 0 /f
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverrideMask /t REG_DWORD /d 3 /f
停用緩解
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverride /t REG_DWORD /d 3 /f
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverrideMask /t REG_DWORD /d 3 /f
