Create a new local account (I use an account called custom_default). Add the account to the Administrators group. Log into that account & configure it as you like.
Log off custom_default & log in with your local admin account. Remove custom_default from the Administrators group. In regedit, go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList & change Default to point to %SystemDrive%\Users\custom_default (instead of %SystemDrive%\Users\Default).
Log off, then log back on to the local admin account. Go to Control Panel & select System. Select Advanced System Setting & under User Profiles select the Settings button. Select the Default Profile (which you pointed to custom_default in the registry) & select Copy to. Browse to c:\Users\Default & click OK.
Under Permitted to use, click Change & give permissions to Everyone. Finally click OK & the contents of custom_default with be copied over default (the original default). After it gets done, go back to regedit & change the back to %SystemDrive%\Users\Default.
