nsi memory leaks fixed yet?

Uninstall IE 11 go back to IE 8 , you will not have any problems after. I suggest to go back to IE 8 and check to see if there is sny windows update excluding ie9,10,11 and after update install ie 9, 10,11 if you still have problem call Microsoft pay $200 if they didnt fix it they will refund the money . And in that case either dont use ie11 or if you want it format the computer dont let windows update install ie11 make sure it goes by order . You will be fine

Hi alenshahnazari and thanks for the feedback.

Please see my 9 November note above.  The rewind to IE8 and then update fix worked on my HP ProBook, but not on my Dell Vostro (both Win 7 SP1 Pro 64 bit).  IE10 gave a 9C59 install error on the Vostro which I could not fix, but IE11 did install (!).  In any case I believe the memory leak on the Vostro restarted with the reinstall of IE9.  Yes, I did check for updates after rewinding to IE8.  All very strange.  I think my problems all started after a massive Patch Tuesday update on 15 July 2015 which coincided with my upgrading to IE11.

Hotfix KB2847346 has fixed it for me (so far!!).

I've just done a completely new build of Win 7 Home Prem SP1, I'm still on IE8 and I have the NSI leakage problem.  Unfortunately neither KB2950358 nor KB2847346 have fixed it either, so who knows.  I'll just have to wait until I get the Win 10 offer, that will presumably fix it.

One or other of the KB's fixed it on my other machines though, it didn't seem to have anything to do with which version of IE I was using.  I suppose if we wanted standardization we'd go for Apple - not that they're doing too well at the moment though.

It looks like this has been dormant for a while now, but I ran into this issue today and wanted to put some info out on how I fixed it. My SVCHost w/ NSI in it was up to about 6 gigs of memory, looking over some of the info in the post I checked network adapters and have a Virtual Box Adapter. Disabling that adapter dropped the memory usage to under 10mb. I did not have to uninstall it, just disable so I can use it later if needed.

Hope this helps.

Yet another machine suffering the same problem.  Both hotfixes installed, no effect.  No VBA installed, so can't try disabling that.  User is aged and doesn't want to learn anything new at their time of life, so 10 isn't an option.
