The more that is running on your computer the more your computer has to close on shut down. Keeping a slimmer running computer will not only make your computer run faster but it will make Windows shutdown faster. Here is how it’s done:
Go to the Start menu and then select Run. Type ??services.msc?? in the Run Dialog Box and click on OK. In the services window double click on the service you wish to disable. In the properties box for the selected service choose disabled in the Startup Type dropdown box. Click on OK.
Its best to restart your computer after disabling a couple of services at a time so if something undesired happens to your computer you know what disabled service needs to be re-enabled.
Go to the Start menu and then select Run. In the Run box type in ??regedit?? and click on OK. Navigate to ‘HKEY_CURRENT_USERControl PanelDesktop’ and double click on the ‘WaitToKillAppTimeout’. Change the value to 1000 and click on OK.
Double click on ‘HungAppTimeout’ and change the value to 1000 then click on OK. Navigate to ‘HKEY_USERS.DEFAULTControl PanelDesktop’ nd double click on the ‘WaitToKillAppTimeout’. Change the value to 1000 and click on OK. Double click on ‘HungAppTimeout’ and change the value to 1000 then click on OK.
