Depends on a few things:
Retail purchase Vs. custom made
Version of OS you’re using (Ie… Home Premium, Business, Pro, etc…)
Other apps and services on that computer.
Retail computers for DAW’s I have always regarded as one step above unusable. Some serious tweaking needs to be done to get these ready.
OS versions are more subtle with the changes that may need to be done.
Other apps fall into two categories.
- Does the app just reside on your computer until you need it?
- Is it running any active services and/or processes continuously?
With those things in mind, in regards to your original question. I would say either no or not to a point where we would be able to tell (in comparison to other OS’s). It is the features that come along with the Windows OS that start to degrade performance.
