The goal of that procedure is to get rid of the Real Time Windows defender scan process that can cause spike when files are used, so you need to “say” to windows defender not to take care of those files into those folders.
When using instrument like Kontakt it can trigger the scan process of the bank files…
So you need to exclude every possible folder that can be used when using Cubase and all those instruments…
Do it to ALL your folder of : Samples / Instruments / Steinberg folders (C:/Program file C:/Roaming / etc…)
