What version of Windows do you run on the Windows servers?
Our Windows servers run using Windows 2016 R. These servers are based on the same specification as all other servers.
Each Dell web server has two 2.2 GHz Intel Xeon (Cascade Lake) 12-core processors with hyper-threading. This gives 48 logical cores per machine. These have access to plenty of fast memory resource: 64 GB 2666 MHz DDR4 RAM.
