intanto ha sbagliato sezione...è un problema riguardante windows, quindi sarebbe stato più appropriato postare nella sezione windows.
in ogni caso si tratta di un servizio di windows:
The service is responsible for applying settings configured by administrators for the computer and users through the Group Policy component. If the service is stopped or disabled, the settings will not be applied and applications and components will not be manageable through Group Policy. Any components or applications that depend on the Group Policy component might not be functional if the service is stopped or disabled.
per disabilitarlo (non dovrebbe essere indispensabile come servizio :look:) segui questa guida:
1- Click on the "Start" button, open the "Run" menu and then type "REGEDIT" into the Run window.
2- Hit the "Enter" key and then use the left navigation pane of the Registry Window to browse to the "HKLM\SYSTEM\CurrentControlSet\services\gpsrv" subkey in the registry.
3- Right-click on the "gpsrv" subkey and click on "Permissions." Open the "Advanced" tab, click on "Owner," select your user account from the list and then click on the "OK" button. Click on the "Administrators" group, click "Full Control" and then click "OK."
4- Double-click on the "Start" key in the right-hand pane and change its value to "4." Close the Registry Editor and reboot the computer. Upon rebooting, the Group Policy Client service is disabled.
p.s. come te la cavi con l'inglese :D
