Windows Services, what changed from Vista to Windows7 Part1

Today I took a closer look at the Windows Services running on Windows7. A lot of the performance improvements with Windows7 are related to the way how and when services are being loaded so i thought it’s worth to see what’s happening there.

I first installed a Windows 7 build 7077 and a Windows Vista SP1 client on my Hyper-V server. Because I am primarily interested in what’s happening in an enterprise environment, both clients were joined to a domain.

To obtain the services data from each system, i executed the following PowerShell command:

gwmi win32_service | select Displayname, Started, StartMode, State  | format-table | out-file c:\data\services.txt

I then imported the data in excel and then the painful work actually started… :-), comparing…. I compared the services that were installed including the start mode and current state. I will talk more about the start mode in Part2.

New Services / New Default Services

  • Application Identity
  • ActiveX Installer (AxInstSV)
  • BitLocker Drive Encryption…
  • Bluetooth Support Service
  • Disk Defragmenter
  • Encrypting File System (EFS)
  • Windows Media Center Recei…
  • Windows Media Center Sched…
  • Fax
  • HomeGroup Provider
  • Media Center Extender Service
  • BranchCache
  • Power
  • RPC Endpoint Mapper
  • Adaptive Brightness
  • Software Protection
  • SPP Notification Service
  • Storage Service
  • Credential Manager
  • Windows Biometric Service
  • Parental Controls
  • WWAN AutoConfig

Some of the above services are available in Vista as well, but aren’t installed by default.


It looks like all “Terminal Service…” type Services  are now called Remote Desktop…..”


The below Services exist on Vista, but I haven’t seen them on Windows7.

  • removed
  • DFS Replication
  • ReadyBoost
  • Software Licensing
  • SL UI Notification Service
  • Microsoft Software Shadow …

* well possible that some of the above “removed” services have been renamed or integrated within the above “new” services.
