Quick suggestion for getting the SQL Developer to work in Windows 10:
- Get the SQL Developer (with JRE) edition. I got bad experience when getting SQL Developer to work with my own JDK 1.8 installation in Windows 10. No matter where I copy the MSVCR100.DLL (It always said JAVA_HOME\jre\bin\msvcr100.dll cannot be launched, crazy). So, just get the "with JRE" version.
- The font size are crazily small on a high DPI screen. So get a larger font, right-click on the "sqldeveloper.exe", choose "Compatibility > Change high DPI settings > High DPI scaling override > System (Enhanced)"
