This is the second computer I have bought refurbished that was prepared by SKYTECH USA LLC. These folks do a great job of refurbishing older computers and the have great support in case things don't go exactly as planned.This is a nice little unit that I mainly use for email and such. It's not a gaming setup by any means and it wasn't my intention to use it as such.It's only been a few days since I set it up but everything works as it should. Its very quiet and runs Windows 10 Pro just fine.My main reason for buying this computer is because all my other computers are running Windows 7 Pro or Linux. Since Microsoft is not going to support Win 7 anymore, I decided to have at least 1 Windows 10 computer on hand. All my other (except for my linux systems) computers will be pulled off the internet since they won't be supported by Microsoft anymore.Personally, I think Windows 7 was a solid platform and I never had any issues with updates like the nightmare things I've been having to deal on my Uncle's Windows 10 computer. Seemes like all of us are the Windows 10 Beta Testers. At least I learned enough from working on my Uncle's computer all the time.Not a huge fan of Windows 10 mainly because of dealing with the aftermath of issues from updates on my Uncle's computer. He's 80 years old and not the most tech savvy type of person.
