因為在系統啟動或使用者登入之前，變更必須先處理，所以群組原則用戶端延伸模組 %8 無法套用一或多個設定。在下次啟動或這位使用者登入之前，系統將等候群組原則處理完全結束，而這將導致緩慢的啟動與開機效能。

The Group Policy Client Side Extension %8 was unable to apply one or more settings because the changes must be processed before system startup or user logon. The system will wait for Group Policy processing to finish completely before the next startup or logon for this user, and this may result in slow startup and boot performance.
