By default, Windows automatically saves all downloaded files into the “Downloads” Folder within the user profile. Since this folder forms part of a user’s Roaming Profile, it will be copied back and forth between the workstation and the server at every logon / logoff. As the size of the “Downloads” folder increases, so will the user’s logon / logoff time.
One solution to this problem is to use “group policy” exclude the “Downloads” folder from the roaming profile.
From within the group policy editor, choose a suitable policy object (one that will be applied to domain user accounts), or create a new one. The key we are interested in editing can be found at: User Configuration => Policies => Administrative Templates => System => User Profiles => Exclude directories in Roaming Profile.
Enable the policy and set the value = “Downloads”
From now onwards, all downloaded files will be excluded from the roaming profile, and will only exist on the local workstation.
