Timer Coalescing

Staying idle requires minimizing timer interruptsBefore, periodic timers had independent cycles even when period was the sameNew timer APIs permit timer coalescing

Application or driver specifies tolerable delayTimer system shifts timer firing to align periods on natural frequency

Timer tick15.6 ms

“Trigger-Started” ServicesBefore, services typically started at system boot and ran until shutdownServices can now specify specific start and stop conditions (triggers):

Device class arrival and removalBthserv: start on bluetooth device class arrival

IP address arrival and removalLmhosts: start on first and stop on last IP address availability

Firewall port eventBrowser: open of NS and DGM ports

Domain join and unjoinW32Time: start on join, stop on un-join

Custom ETW eventAppid: start when SRP enabled

Triggers are stored in service registry keyUse “sc qtriggerinfo” to view service triggers

Virtual AccountsWant better isolation than existing service accounts

Don’t want to manage passwordsVirtual accounts are like service accounts:

Process runs with virtual SID as principalCan ACL objects to that SID

System-managed passwordShow up as computer account when accessing network

Services can specify a virtual accountAccount name must be “NT SERVICE\<service>”

Service control manager verifies that service name matches account name Service control manager creates a user profile for the account

Also used by IIS app pool and SQL Server

Managed Service AccountsServices sometimes require network identity e.g. SQL, IISBefore, domain account was only option

Required administrator to manage password and Service Principal Names (SPN)Management could cause outage while clients updated to use new password

Windows Server 2008 R2 Active Directory introduces Managed Service Accounts (MSA)

New AD classPassword and SPN automatically managed by AD like computer accountsConfigured via PowerShell scriptsLimitation: can be assigned to one system only
