Pros: - so my first experience with Windows was the 3.1 version, and I used most of them since, this one ranks about 3rd after XP and Windows 7 - they constantly improve this product as it supposed to be the last Windows, and they do listen to the community feedback - works well, very stable, rarely crashes - great improvement over Windows 8 - trouble free install on a SAMSUNG 970 PRO NVMe

Cons: - it supposed to be the last Windows, so what choice do you have? - lots of privacy concerns turn on by default, and other resource intensive processes that are not needed - update process was better on previous versions of Windows, many times it gets stuck at a certain %, then you toggle the screen and you will see that the progress bar moves - suffered from a fuzzy text, when laptop was connected to external display, which eventually got resolved through one of the feature pacts

Overall Review: I went for a retail since Microsoft is not releasing anymore PC based operating systems in the future, it is better to have a hard copy on hand then rely on OEM. Go back to Windows 7 update model allowing us to select updates we want to install, turn off telemetry and all those resource hogging useless processes, and privacy settings on off, then I will give it 5 eggs rating

Overall Review: As an electronic delivery purchase, delivery should be instant, or at least on the order of minutes. It took a couple days to get my key.

Pros: This is a lot like Win 7 but it does have elements from Win 8 and 8.1 (such as the tiles and modified start menu). Very stable and reliable Doesn't take as much RAM for background processes when compared to Win 8 and 8.1 About $10 more than Win 7 Support is relatively average for a busy company like Microsoft.

Cons: Personal issue: Some of the items move to certain places and if you search for certain things they may not come first (such as task manager). Cortana is something that takes time to calibrate if being used. But it does get better over time as it recognizes your voice.

Overall Review: If you don't know where or how to download/install Win 10, then please use the following link: http://www.howtogeek.com/197559/how-to-install-windows-10-on-your-pc/ I recommend making a disc and/or usb copy of the windows install for a rainy day

Pros: - Easy download, immediate delivery - Retail version for worry free unlimited hardware changes - Official, Microsoft approved - Peace of mind

Cons: - N/A

Pros: It's the latest Windows.

Cons: Well I had a bit of a problem with this one but I think my situation is unique to only a few people. I bought new components to rebuild my PC and the motherboard required Windows 10. I was using Windows 7. So I bought Windows 10 and installed it. BUT because of the hardware changes I made to the PC I couldn't activate Windows as it wasn't associating this new PC to my Microsoft account. Also I followed the link sent by Newegg and it downloaded Windows 10 Pro not Windows 10 Home Full Retail which is what I bought. I had to talk to Microsoft and let them take control over my PC to correct the problem. It took much longer than it should have.

Overall Review: Windows 10 is fine, but if you've made a lot of changes to your PC then I highly suggest that you skip the middleman (Newegg) and buy it directly from the Microsoft website as that way they have the proof of purchase and it will associate it with your Microsoft account.

Pros: ...Download the Full retail copy instead the OEM....The Key was emailed to me in few minutes.Easy instalation and OS work fine.I'll create a boot usb drive.

Cons: none

Overall Review: For a few more $$...get the FULL RETAIL version instead the OEM.The DOWNLOAD option is cheaper

Pros: Worked great. Worth the 20 more bucks than OEM versions. I set up a boot USB drive with microsoft web site. Bought this and got an email right away, good to go. Booted up the new system with the drive and used the activation key I received and that's it. If I ever need this on another system I can reuse it. The code stays on Newegg so you can always look it up if you need to as well.

Cons: none. its good. wish it cost less, but whatever. Needed it.

Overall Review: I'd recommend. I'd do it again, no regrets. Would not change anything. Went very smoothly for me. If I did not have a computer to set up the USB drive, maybe I would have bought a copy that mailed me one, idk. But for me this was perfectly good and I am happy with the result.

Pros: This applies to the download version. - I got the key delivered to my email. - I got my activation key in about 30 minutes, according to my email history. - I didn't have to wait 3-7 days for a physical copy to be sent to me. - My Windows activation worked flawlessly. - Life is good.

Cons: - Worried about how and when the key would be delivered to me. - I don't get to put a sticker on my computer with the key somewhere.

Overall Review: I'm not reviewing Windows 10 itself. I am reviewing the digital delivery of the microsoft windows key. I got the key in an email, and am very happy. Thanks Newegg for providing this speedy service. Make sure you print your email with your key and store it in your computer case somewhere.
