Yeah, for me it is the ads. No one likes ads, but I hate ads more than most people. So when Windows started putting more and more ‘recommendations’ into various places… I’ve been building up a list of registry tweaks to turn it all off - but as more ads got added, just couldn’t tolerate it any more. I installed Mint with dual boot (defaulting to Mint). I thought I’d be booting into Window every so often for one reason or another, but as it happens - the only reason I ever loaded Windows was to check that the dual booting was working.
