With Nod32 installed both discord and adobe creative cloud apps EAT cpu time. Uninstalling Nod32 or excluding the relevant discord and adobe folders in Nod32 eliminates the issue. No malware is reported, no viruses, etc. etc. - either by nod32 or by windows defender. So it definitely points to some incompatibility with the imminently incoming version of windows 10, discord, adode creative cloud (and possibly other apps I don't use) and Nod32.
