P: Menu too small on Windows high res display

The following post from below fixed this issue for me.  I had tried doing all of this before except for changing it from "application" to "system"... Now as stated,  all is Well.  Thank you!

It does works.  The only issue that remains is the brushes are no longer accurate... they sample and paste quite a bit beyond the selected brush size & hardness.

the solution from David Williams worked perfect with me

my problem still hasn't improved. I'm so sorry. Value data is not decimal

I'm so glad that I found this website and this post!! Thank you SO MUCH!! This solution completely fixed my problem.

Thank you so much, @Green Eyed Bali Bule, that is just what I needed.  Appreciate the solution.  Worked on my Windows 10, 64-bit machine running (gulp) Photoshop CS3 (I know, I know!  But it doesn't require a subscription!) on a 3840x2160 resolution monitor.  There was no way I could have seen the CS3 user interface without changing the high DPI settings to "System (Enhanced)."  Perfect now.

I'm running Photoshop CS4 Extended on a Windows 10 Pro 64-bit machine with an Asus MG28U UHD 3840 x 2160 display. I had scaling issues with Photoshop menus in addition to seeing 3 cursors in the Photoshop window. With the following display and executable file settings, the duplicate cursors are gone, and the menus appear at an acceptable size for my use:

Notes
1. I had to  repeat steps 7-19 for the Photoshop application file in both Program Files and Program Files (x86) for the solution to work.
2. I'm the only user on my computer. If there are multiple users, then at step 13 you may have to select "Change settings for all users."

Display Settings
1. In Windows 10, right click on desktop and select "Display Settings"
2. Under "Scale and layout," select "Advanced scaling settings"
3. Under "Custom scaling," enter 151
4. Hit "Apply," sign out, and sign back in (signing out will close all applications, so make sure you save important files)

Photoshop Executable File Properties
5. Right click on the Windows icon in the corner of the Windows taskbar and select "File Explorer"
6. Open Local Disk (C:)
7. Open Program Files (x86) folder
8. Open Adobe folder
9. Open Adobe Photoshop folder
10. Right-click on the Photoshop application file
11. Select "Properties"
12. Select "Compatibility" tab
13. Under "Compatibility mode" toggle "Run this program in compatibility mode for:" and select "Windows Vista (Service Pack 2).
14. Under "Settings" toggle "Run this program as an administrator"
15. Under "Settings" select "Change high DPI settings"
16. Under "Program DPI" toggle "Use this setting to fix scaling problems for this program instead of the one in Settings"
17. Under "Use the DPI that's set for my main display when," select "I open this program"
18. Under "High DPI scaling override" toggle "Override high DPI scaling behavior, Scaling performed by:" and select "System (Enhanced)".
19. Hit "Ok" then "Apply"
20. Run Photoshop to confirm the settings work.

Hope this works for some of you too!

I did the Registry hack and then the compatabiliy fix above. Restarted and all is good.

This has been going on for several years.  Seems to me that if Adobe wants to charge a monthly membership fee, they should fix this yesterday.  No reason it can't be fixed.  Everything is fixable if it's a high enough priority.  Please, Photoshop, FIX this problem.  Otherwise, will we be getting a discount because we can't use your software?
