Then an update replaced my work.
It wasnt some 'uninstall program', but a multi-step process that involved registry editing.
I don't feel like I have control over Windows.
My friends would be like "do you want to play games?" and I'd be like "yeah hang on while I make some boot media so I can recover afterwards."
Today I can't get rid of ads/news/cortana/edge.
I worked around this by installing Ubuntu on a second SSD, then I can use my bios menu to change the boot device.

If Windows is removing another OS's entries from the boot list (displayed when you run 'efibootmgr -v' in Linux) then that's 100% deliberate anticompetitive behaviour from Microsoft; this list is where the entires like Windows, Fedora, and so on appear in the list of boot entries your firmware shows you.
You still had some amount of control on 95. MS had the power to take your control away at any point, but they didn't at that time.
However, I do feel your pain, I don't understand why other motherboard manufacturers don't save your existing BIOS settings. Asus and MSI, I'm looking at you all... why can't you just ask me instead of undoing my work?
