I'm not sure you can do this in IE11 as that functionality was supposedly removed, but this might work as alternative for your (possibly broken) program. Not direct GPO but if it works it's a starting point.
https://ewingco.wordpress.com/2013/11/26/how-to-disable-tab-browsing-ie-11/ From: [email protected] [mailto:[email protected]] On Behalf Of David McSpadden Sent: Friday, February 17, 2017 8:59 AM To: [email protected] Subject: [NTSysADM] tab in IE11 I need to know what to set in Group Policy for IE11 32bit or 64 bit computers to disable the tabs. I need to either just continue reusing the same tab or open whole new windows. I have an app that has to be default tab of the active window or it blows up. Right now I have two settings in IE11 set in GPO but when opening this app it goes to a new tab in the current window and if I 'tab' back to the original tab the app fails to work. [cid:[email protected]] any ideas?
