It doesn't suck. It defaecates in reverse. To suck, you need a mouth, generally. And losedoze 10 doesn't, it has a second anus, which it needs to be full of shit on such an extraordinary magnitude. It is worse than just a fucking pile of steaming stagnant shite, its a disgusting, foetid abortion, something that got sucked out of the cheese-infested stinking twat flaps of a swarthy, sweaty arab burka bandit teenage mother, and despite measures taken to cleanse the place, which escaped from the hospital garbage bins to go running around the micro$oft programmer's team offices and stick the coathanger poking out of both sides of it's head into the electrics, fucking things up all over the place to an even greater extent than the 'now its written, go in and make sure it is sufficiently fucked in every last arsehole from the front, the back, sideways, diagonally and upside down. Then to bugger it up some more and make sure it is disgustingly bloated too' team infested it.
Fucking hell, though, M$ can't half make a worthless piece of noxious, bloated, barely usable, slow as hell and cosmetically brain-bleach-worthy shite as an excuse for an OS.
The worst thing is, the earlier ones, bar some issues, were better than the ones now. They just fell to shit after XP, and just seem to be getting worse, and worse, and worse. Uglier, slower, and more infested with bloatware and spy tools and backdoors. Not spy-tools for users either, for the OS to phone home and report all sorts of stuff to M$, and in a lot of cases making it fucking difficult, or impossible via the OS itself, without employing a firewall to block the traffic, or patches if available. All sorts of registry keys that I don't trust either. And the fact that 10 was developed 'with the assistance of' the NSA, makes me want absolutely nothing to do with it.
I had a computer that came with a windoze 10 infection once when it was bought, and it was almost impossible to purge the OS from the computer. Even trying to format it was unsuccessful, I had to have someone else put the HD in a hotswap drive tray with another operating system running and do a low-level format, before finally, just to be sure, doing a guttman-wipe on the entire drive, including blank space, to make sure everything was irreversibly and completely extirpated.
Couldn't get rid of it from the computer the infection was afflicting, even with months of trying, until I finally was able to get the help of another to use their machine for the extermination. That, along with the multi-pass overwriting (well, I didn't even want the ghost of that filthy parasite-ware to remain un-exorcised. Damn thing just degraded within a couple of weeks to where it was so unusable it couldn't even display a login screen and showed a massive white square block instead of a mouse cursor. After first slowing down worse and worse until even the fast hardware it was running on, didn't stop it from being about as fast as frozen treacle.)
Utter, abject, pitiful slack-jawed dribbling imbeciles must have coded that swill.
Total, absolute trash. I wouldn't shit on it with somebody else's arsehole.
