Windows 10: audio dropouts on multi-core CPU setups

Thanks. Is it possible to roll back to 7 from 10? I would assume not as I’ve never held a licence for 7.

Also, how do you keep plugins updated if pc isn’t on the net?

I keep getting getting real-time peak spikes on the cpu meter too - would this be because my samples are on my D: drive, which is a normal spinner and cubase is installed on C: which is an SSD?

Such a headache all of this
