Lately I've been getting into privacy in IT and thought to myself: How could you make Windows more privacy focused? I know this is a somewhat impossible task but you can always at least try. There are some crazy ones out there like this one called Windows Optimize Harden Debloat which takes it to the extreme in my opinion and I have it installed on my laptop currently and I tried it for a bit but overall it takes away a lot of comfort that people are used to and I doubt anyone's willing to give all this up just for some privacy.
Also read the warnings on the GitHub page or you might end up having to reset your Windows installation!
There are less intrusive options out there though, like Privacy.Sexy which still gives you control over what you enable or disable and at the same time won't take away anything that would basically limit what you're used to. For my PC I went with that and noticed no difference really. The options I chose were the strict setting and disabling "Privacy Over Security" as if you do not have a 3rd party anti virus installed, you'll end up with none!
So if you wanted a tutorial for Windows:
Another program worth mentioning and probably installing is WindowsSpyBlocker which simply puts a lot of IPs in your hosts file to block, all of which are used by Windows to collect your data. You have to run it every now and then to stay up to date though, perhaps not something for everyone but certainly worth a look if you want to be serious.
Most people use their browsers for almost every task they perform online, so I'll also let you know what I've done in regards to my browser to make it more focused on privacy.
First I tried out LibreWolf which is based on Firefox and not Chromium and for me that didn't quite work out as Spotify wouldn't play most songs and the ones it did play, it would stop playing any sound after about 10 seconds, so that was a no-go. My next choice was Brave as it's yet another privacy focused browser but it's built on Chromium. It gave me a way better experience right away and everything basically worked the way I'm used to. I also put the tab bar on the side as it allows for more tabs open at once, just a little pro tip from me ;)
Update of 2023-08-10: I have switched from Brave to Firefox, mostly because there is some controversy about the Brave CEO as he is against gay marriage but also because some websites actually suggest Firefox over Brave but you can certainly decide on this for yourself. One thing I dislike about Firefox currently though is that it doesn't allow for vertical tabs OR grouping of tabs which is a big shame. Thus I've installed addons that allow for this (Power Tabs) and added some other stuff that prevents the tab bar at the top from showing but this is besides the point of this blog post.
Now all I had to do was install some extensions and here's a list of the ones I have installed with some little extra information:
