JNLP files won't run from IE11 on Windows 10
I had the same problem after installing Windows 10 update.
Cause / Solution: I have both 32-bit and 64-bit JRE (Java 8 Update 131) installed on my machine. This was not a problem before the creators update. Java applications and Java Webstart applications worked fine in Internet Explorer 11. However, Internet Explorer 11 (11.332.15063.0) seems to have problems with the 64-bit JRE. Java Webstart applications can only run if only the 32-bit JRE is installed.

Alex, it looks like our friends at Oracle heard you loud and clear. According to the JDK Bug System, this issue is tracked under the JDK-8185661 defect . A fix appears to be under development for inclusion in an upcoming critical update (CPU) update.
In the meantime, it is possible to test the fix on a development system using the Early Access Build downloaded via Oracle Java Early Access Downloads page After reproducing the issue with JRE 8u151 (1.8.0_151-b12) on Windows 10 version 1703 using IE 11.0.44, I checked the issue as fixed after upgrading to early access JRE 8u162 (1.8.0_162-ea-b01).
