That being said, how often is system update happening for you that its really a problem? It's a point that I see being repeated over and over, but I don't think I've had any interruption at all from system updates, beyond windows doing the occasional update before power down.
And also about the housekeeping activities -- Why would it continuously seek? Beyond fragmenting, indexing or defender scanning your files that shouldn't be happening, and I don't think I've ever had that be a problem...
