When right clicking a Windows 7 machine on a domain and clicking personalization you receive an error ‘unspecified error’.
This occurs due to ‘personalization’ not being accessible from the control panel.
To resolve this, access an existing group policy or create a new one.
1) Access User Configuration > Administrative Templates > Control Panel > Show only specified Control Panel items
2) Add Microsoft.Personalization
3) Log off Windows 7 machine, log back in and try again.
