Hi,
Since some releases I always see a popup from ccleaner on machine start that says "suspected commercial use", where there is abosuletely none, I don't even known how ccleaner tries to do this check. Yes it's a Windows 10 Pro license and I do have a domain network at home because I'm an IT professional and also some developer software which I use for my own personal pet projects which are not commercial, published or sold in any way not even as freeware or open source. For work I use another computer from my employer that is connected to same network but there I didn't install ccleaner
