You might find a Registry hack to do the job, but you are trying to use old software on a new computer, and they are incompatible. If took the plunge with CC you'd be OK, so it's up to you to decide.

You can try Edit > Preferences > Interface > UI Font Size: Large
Sadly though, a resolution of 1920 x 1080 would be best.

Notice how Photoshop is the only application for which you gave the version?
As has been mentioned you are apparently combining obsolete software with more current components (screen, OS, …) so you can either accept the consequences of your choice or spring for the current version – for which there are, unfortunately, no perpetual licenses being sold by Adobe.
I just upgraded to Photoshop CC 2017 18.1.1 and had the same problem with the components of the workspace being so small that I just couldn't work that way. You may have already found this, but in addition to trying Edit > Preferences > Interface > UI Font Size: Large (Thank you Bahaar Khan!) you can use
Edit > Preferences > Interface > UI Scaling: 200%
I tried this and it did get bigger, but it's still too small for my taste.
I'm using Adobe CC, last version, in Windows 10, with a 4K monitor display.
