Been there, done that. Tried all possible tweaks. All reinstallations were from newest installers. Nothing helps.
Slight increase in performance, i.e., slightly faster post boot system stabilisation after deleting HP printer useless extra software. Noted that Chrome is a huge resources guzzler. But that does not explain why system, once it is stabilized, behaves perfectly.
Please understand: computer performance is perfect, _but only after a 20-30 stabilisation period_ which is an unaccepable long time, and impedes normal work because all reactoons of the machine, keyboard, mouse, app launches etc. are reduced to a crawl.
Note that stabilisation involves disk activity, which drips from 100% to 50 only after 10 minutes, then to 1-2% only after 10-25 minutes.
Then, apart from operation, momentarily calling for higher disk activity, everything remains on that low percentage.
Note also that this problem only appeared after 1903 update ( which could only be done after a totally clean update).
No offered solution or tweak has helped up to now.
So there you are.
