Everything Search Engine was also not working for me.
Before, compiling the .ahk script to .exe would solve any issues.
Windows 10 gave me problems again.
The following information helped me fix it:
On Windows 8 and later, UAC can only be disabled by modifying the
registry, and doing so breaks apps.
As I said, "turning off" UAC in Control Panel on Windows 8 and later
just suppresses the Yes/No prompts; programs are still run with
limited privileges by default.

disable UAC via the registry, you’ll need to head to the start menu
search box and type in regedit.exe and browse down to the following
key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
Over on the right-hand side, you should see a setting for EnableLUA,
which you’ll want to customize as follows:
UAC Enabled: 1
UAC Disabled: 0

Also on the howtogeek page:
Just download, extract, and double-click on the included
ReallyDisableUAC-Win7.reg file to disable UAC.
You’ll need to reboot for the setting to actually take effect.
There’s also an included registry hack file to re-enable it as well.
Disable UAC completely. As you noted, this will kill apps on Windows
10 (or 8).
Create a patched executable using EnableUIAccess, and then use that executable to run the script.
