I'm using NIS that came with the Gigagyte motherboard disc. The version is has been updated to 21.5.0.19.
NIS does not start straight away when the machine loads. The icon takes a minute or so to load in the system tray and there is no process in the Windows Task Manager.
I enabled the Boot Time Protection but that worked for the first restart but it has gone back to taken a while to load at the startup. The Boot Time Protection is still enablabled.
I have NIS on my other computer and I don't have this problem.
