I have a system76 machine that I've used for years without any difficulty until my kids school said she needed access to this weird OS called Microsoft Windows that I don't know much about so I got a second drive and resolved to try this Windows thing on a secondary drive.
Installing the physical drive was the easy part. Everything after that went south. First instead of just going to windows.com or something I got shunted to stores where they were selling entire computers. I didn't NEED a new computer just an OS. Then I found people selling things called cd keys. What are those? Who even buys an OS anymore?
Eventually I figured out you can download something called an ISO file (what is that?) from microsoft and pay for it later? It looks like I'll be paying hundreds of dollars for what comes standard with Linux isn't that crazy? Then I tried to "burn" the iso to a usb drive and THAT didn't work so I borrowed a portable usb optical disk and bought some writable disks at Walmart like it was 1999 and finally got it installed whereupon it took a giant shit on my computers ability to boot anything except Windows. At first I thought it destroyed all my data on Linux and I about had a heart attack but after hours of troubleshooting I realized I just had to restore the ability to choose my OS at boot time and all my data was still there and I calmed down a bit.
Then I booted up this "Windows". At first nothing worked including the internet so I had to do research on my phone. I discovered that unlike Linux windows doesn't actually come with the drivers needed for your machine you have to go to each manufacturers website and navigate their confusing site (and avoid malware sites offering drivers) and find each individual driver. If you ever need an update you will have to do this all over again unless the driver includes an auto update feature. For the stuff that does auto update if it ever causes a problem with your hardware it will probably be impossible to fix and you will just end up reinstalling windows all over again and hopefully realizing what tanked your install in the first place and people actually do this over and over again!
It had a mediocre but acceptable set of default applications. Not nearly as good as my computer came with but its ok. Then I went to install some software I'm used to and I discovered the windows app store unlike Linux has almost nothing of value and one is expected to do the same dance as above for applications just like drivers. While downloading from a seemingly legit site I acquired several weird pieces of adware and an actual computer virus. Something I had previously just read about on the internet. Good thing this insecure OS didn't have any of my actual data!
It's not surprising that few people use this "windows" thing. It's a total mess and not nearly ready for prime time. Maybe 2030 will be the year of the Windows Desktop.
