Like it or not, commercial computing is primarily Microsoft environments. Businesses are moving to Azure/O365, but there's still a lot of on-prem AD out there, and a lot of businesses that are stuck in between with some form of hybrid hodge-podge. It's definitely more difficult to do admin tasks for individual Windows endpoints vs. Linux, but on the other hand there is no FOSS equivalent for AD forest management. In a corporate environment, the ability to manage large numbers of endpoints at scale is more important.
If you have to manage Windows systems you should learn about Windows-native tools, rather than trying to drag the Linux-native tools you're used to onto Windows just for the sake of familiarity.
That said, installing (and updating) software on Windows is absolutely a pain compared to the relative simplicity of a Linux package manager and I'm 100% with you on that. I highly recommend chocolatey, which attempts to work as a package manager for Windows. All of the software that you install with chocolatey can be updated with a single command, similar to running updates in a package manager on Linux. If you can implement this on the Windows systems that you have to manage, it will make things easier.
