My old XPS 420 computer ran on the Microsoft Vista operating system it shipped with, which would indicate how long ago I bought the system from Dell. Too many hardware items no longer function, or worse, function intermittently, to indicate here.
Suffice it to say, it was time to retire the old boy.
The new system is a 4th generation Intel Core i7 CPU, running at 3.6 Ghz with 12 Gigs of memory and a 1 Terabyte hard drive. It came with a corded keyboard and mouse, and a Nvidia GTX-745 graphics card with 4 Gigs of RAM! It has 6 USB ports, an HDMI port in addition to it's normal video output, as well as built-in audio, WIFI, integrated LAN and Bluetooth capability. Here's the kicker, it came with Windows 8.1.
Problems With Dell

Problems With Windows 10
So OK, I power the computer up and start transferring and installing to my heart's content. This went swimmingly for two days. Then I chose to take advantage of the free upgrade to Windows 10 opportunity and waited a good hour before that was completed. This was a major mistake.
For whatever reason, Windows 10 set all my files and folders to "Read-Only" and I couldn't save word documents or backup my financial files. I spent another two days adding Administrator privileges to my account and resetting the files and folders to Read/Write, three separate times, but the changes would not stick. Every time I restarted the computer, the files and folders were Read-Only. Thank you, Microsoft and Windows 10!

Over the weekend, when I knew they were not available to assist, (they don't assist much anyway), I managed to download their Recovery software to roll back to Windows 8.1. That worked, but I lost everything I had loaded and installed to that point. I didn't care because I thought I was returning it anyway. Well, a new monkey wrench into the works. My old system gave up the ghost and died. I couldn't connect my Bluetooth keyboard and mouse so I had no way of doing anything. I had second thoughts about returning the new system about that time.
After a good night's rest, I realized I could connect an older USB mouse to the old system and recover some of the files. The new corded USB keyboard and mouse would not work on the old system, of course, because it needed drivers for them. The old system is so old, Dell doesn't provide new drivers just like Microsoft doesn't want to support Vista or any other old operating system.
There's More
Now Windows 8.1 won't let me change the Account or Screen Lock photos. They worked fine the first time around, but now it's rocket science to get them changed. In my search for a solution, I found this is a common problem and complaint. Microsoft still hasn't figured out how to produce a flawless operating system all these years later. I was around for Windows 2 and MSDOS so I've seen many different attempts at the operating system game from Microsoft over the past 35 years.
So unless you are a computer guru, you might want to get your system installed and your important data transferred by someone who has more experience than I do. This was not a very pleasant experience.
