First, WE LIKE DELL COMPUTERS! However, ff you buy this computer and are running Windows 7 or 8 or 8.1, be sure to TURN OFF THE WINDOWS UPDATE FUNCTION in the Control Panel! Microsoft has now stopped simply encouraging the use of their flawed Windows 10 OS and has started INSTALLING WINDOWS 10 WHILE YOU ARE SLEEPING!! You'll come to work and, rather than starting your day, find that your computer has a completely new operating system - one that YOU DID NOT GIVE MICROSOFT PERMISSION TO INSTALL!! If you accept the Windows 10 installation, you will be face with hours of work reinstalling your programs and applications.  If you decline Windows 10, your computer will attempt to recover your previous Windows operating system.  All of your applications will have been deleted, and in many cases - as it was for us - your computer will no longer work AT ALL!!! A complete re-installation of Windows will be required, from scratch. Oh, and you better have a back up, since you are also likely to lose all of your valuable data files!Even though this would be considered by any reasonable person to be criminal "breaking, entering adn vandalism" assault on your owned property, costing you loss of valuable data and at least a day of your time, you will find no sympathy or only meager and unskilled foreign tech support from Microsoft. Their intent is to FORCE WINDOWS 10 on everyone, like it or not. This is an outrageous BREACH OF CUSTOMER TRUST. If you have tried Windows 10, you already may know how many issues are associated with this neW OS.We have tried to find and join an open Class Action Lawsuit that would address Microsoft's gross negligence, as there are many many angry customers like us and this matter is well documented. Unfortunately, so far, law firms that have begun this process, have dropped out due to the high costs of litigating against this greedy megalithic company.You may wish to consider moving to Apple. If not, at least protect yourself and your new computer. TURN OFF AUTOMATIC DOWNLOAD AND INSTALLATION OF WINDOWS UPDATE. Learn about EVERY Windows Update, BEFORE you install it. You have been WARNED! Good luck!
