Does the windows 10 installation tool remove programs?

I am referring to this tool.

Only if you tell it to remove all Applications / Files when you upgrade.

Ok thank you, this may have seemed like a stupid question, but I didn't know if it meant just windows 8 metro apps (it said apps) or installed programs.

Before using the Microsoft upgrade tool, I had the latest version of Speccy system information tools installed. After the upgrade, the Speccy information tools were no longer installed on my computer. All of my other programs were intact. So I presume there was something incompatible about Speccy and the Windows 10 installer got rid of it. I did not request any uninstalls.

If you're using the free upgrade, be sure to let it keep everything, or the Win 10 installation will not activate. (At least, it didn't for me.)

I don't recall having seen that little detail in any of the documentation.
