Bought for Windows 10 on a Dell pc.I prefer to buy a refurbished Dell with Windows 10 installed, rather than upgrading an existing pc.  Windows 10 is extremely picky about current drivers and Dell pcs have a lot of proprietary hardware/drivers.  Pc was quickly delivered and securely packaged.Check the original Dell pc configuration using the Dell Service Tag.  This pc had the original graphics card removed anduses the embedded graphics feature.The refurbished pc is very quick, with a clean install.  You do need to avoid the Microsoft online features, I only use the offline features.  MS really wants you to create an online account.CrystalDiskInfo is freeware the quickly shows the hard drive power on hours and power on counts.  These refurbished pcs come with used hard drives, I prefer to clone to a new drive.  Why chance a +40,000 hour drive?Used for streaming music.
