Of course, I have already switched to laptop. What else can you use the PCs for?
(On the idea to sell the things, I've come alone!)
I give away my to people who can't even afford a smartphone (I'm just one for the resident of ABW {outpatient assisted living) ago - should of course start at the push of a button "certain applications, without too much contact with OS to come - that's a challenge
You could use the best of the components as an office PC only for typing. Of course, depending on the BS, without Internet.
Sell or give away the other to hobbyists. If necessary still electronic waste.
I recommend to install a Linux distribution. For example, Lubuntu. This is an official Ubuntu devirat only with the difference that Lubuntu uses the LXDE desktop which needs little system resources. Otherwise it is 100% compatible with Ubuntu. Here is the download:
32bit: http://cdimage.ubuntu.com/...p-i386.iso If it has less than 4GB of RAM
64bit: http://cdimage.ubuntu.com/...-amd64.iso From 4GB RAM or higher
Then write the required ISO with this tool https://unetbootin.github.io/ on an empty USB stick. Then boot the stick. If the PC can't boot from USB, here is a boot CD that contains a USB bootloader: https://download.plop.at/plopkexec/plopkexec.iso Burn this ISO to a blank CD with this tool: http://www.freeisoburner.com/ Then insert the created stick, insert the burned CD, restart the PC and from CD boot. Then the boot entries from the stick appear and you can start the installation of Lubuntu. I recommend selecting the item OEM. You should choose full installation for the graphical installer. When the installer gets to the point of creating a user account, choose oem as the name and oem as the password. Upon completion of the installation and restart, Lubuntu will start in OEM mode. Then the following must be done:
Start menu> System tools> LXTerminal. Enter the following and conclude with Enter:
sudo add-apt-repository ppa: ubuntu-mozilla-security / ppa
sudo apt-get update -y
sudo apt-get upgrade -y
sudo apt-get install flashplugin-installer vlc
When this is done, click on the OEM icon on the desktop and wait for the system to shut down. Normally it will restart now, but we will turn it off completely.
Now if you want to give this computer to someone and he turns it on, then the graphical Lubuntu Setup Assistant starts. There, the user must choose the language and create a username with password of your choice. Afterwards he has a running Lubuntu with the latest Firefox, Flashplayer, Libreoffice, VLC player and productive tools. A centralized update manager keeps the system and applications up-to-date. You do not have to update every single installed program, as with Windows. The updating can also be automated so that it runs in the background.
If you want to install additional programs, go to the start menu> System Tools> Software. This is operated like an Appstore.
By comparison, Windows is a lame duck.
