Microsoft is retiring its MCSA, MCSD and MCSE certifications
I got my MCSE exactly 20 years ago; it had a different meaning at that time, S was for System, not Solution. Today the company I work for has close to 100,000 computers in Active Directory and no plan to change that: most of these computers are personal laptops and desktops, there is no move to cloud for these. I have no idea what training and certification the new hires working in the AD and Personal Computing teams will have to pursue, I will have to check but it is definitely not a change in favor of simplicity.
