No operating system (although in some cases it is a "+")
Not everything is so simple with the initial launch of the system (you will have to dig into YouTube and on the official website to install all the drivers. I didn’t see the ssd from the package and there was no way to install windows (there was nowhere to download), so I had to look for drivers on the ssd (well, that’s all the rest) dug around for a day, I'm not very strong in all this, but with video guides everything was quite simple, you just had to carefully watch and read what and how to do (you will need a flash drive and another computer to download all the drivers). Then, after installing the driver on the ssd, I installed windows and ated the remaining drivers (I suffered with Wi-Fi for a couple of days (already forgot why), in general, until you install all-all drivers from the official website, the laptop does not fully work (I just warn you) for it wasn’t a problem for me, I had free time, so I sat and figured it out. Then, as I used it, the driver from the video card flew off: I left a file with it on the desktop, it came in handy a couple of times when fps in games just disappeared (the laptop switched to integrated graphics ). But I knew all about it when I bought it, all this can be missed because of the cost) I bought for 70, I would have ordered a month or two earlier it would have been 55 (competitors started from 85)
