No you don't but that's up to you.I know I need the 3 year support from Dell. Hade that before. It was worth it.Then by all means keep them.I like my monitor. It is very big, Dell. And my mouse I like. It's a roller ball.If you're going with a desktop then I'd recommend at least 6GB of RAM, 8 is better, 4 is the bare minmum. You only need a computer not the mouse or monitor unless you want to upgrade those as well and you can get a good one for under $200.My computer is maybe 10 years old. Desk top, Dell I don't have a disk for 7. No on downloading a program and taking a screen shot.Okay, first off how old is your computer? Desktop or laptop? Who made it? (Dell, HP, Compaq, etc). Do you still (or did you ever have) the Windows 7 disc?
I'd like to know the specs, do you know how to download a program and take a screenshot and post it?
It's not that hard to upgrade and most likely you can still do it for free you will need a thumb drive that's at least 4 gigabytes, Download Windows Media Creation Tool & Rufus to install the tool on the thumb drive. None of that is hard.
To start though you want to backup all your files (Documents, Pictures, etc) to a different thumb drive or to the "Cloud".
The "Cloud" is nothing more than storage and data retrieval that is not physically attached to your computer, it's accessed via the internet so you upload or download your files to or from it. You can use Google Drive, Amazon Web Services, Drop Box, etc for free up to a certain amount of storage, more than you'll ever use unless you're dealing in media files (music and video).
You'll also want to save your settings and bookmarks (in whatever browser you're using) as HTML, also very easy to do.
The reason to back up is there are typically less problems with doing a clean install than trying to upgrade and keep your files.
Once you've installed Win 10 then we can help you make it look and act more Windows 7 like.
I do have Word, and the other program that is harder, forget the name. It was kind of expensic=ve. I have a good monitor that is large and a good keyboard and mouse that I would like to keep.
I see some towers that are 4GB and that is too low, right? I should have at least 12 gigabytes. All I use the computer for is making forms, doing crossword puzzles, reading Drudge and the message board. I like to look things up, but like I said, it's hard with Google. Think I may have Google Chrome.
Here's one that's most likely perfect for you. It's a mini tower and the hard drive is HDD as opposed to the faster SSD (solid state) but it's 2 TBs with 8 gigs of RAM. You can get the 3 year protection plan from Amazon for an extra $50.
