We did some (informal) testing of IE11 (US) on Windows 7sp1 (US). Since this is getting pushed out soon by Microsoft, I thought I'd share the results here:
Ruckus Web UI
partial failure (Dashboard widgets, Maps) - configuration/monitor works.
DPSK/Zero-IT - No issues
I believe all tests were on 9.7 (LCS)
If you see anything different...pls share here.
