I can see this, too: It takes 160s to reconnect the network drive. you can try it. not really.Open regedit.exe, go to "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender" and set the value DisableAntiSpyware to 1. Can these be speeded up? I don't use any network drives, so could these be disabled? you can disable both if you don't need them. Windows includes the advanced config UI. Look at the admin options in control panel.
