Hang of Windows 8.1 requires power off, reproducible.

I'm getting a complete hang of Win 8.1 after installation of the latest patches.

Detail:  Logging on to Facebook, using IE11.  No Mouse, no keyboard, no Task Manager...  One other browser, FF, tested no problem.

Desired:  Is there somewhere I can report this quickly and cleanly.  I don't have time to endure a lengthy diagnostic session.  (Quick check of Event log gave nothing that jumped out at me as the cause.)  I just want to make sure that it is reported without wasting time.

Thanks.

Hi,

I have Windows 8.1 with latest Windows patches and I can successfully login to my facebook using Internet Explorer 11 without any errors. So it's not a default issue with Windows 8.1 IE 11.

I would recommend you clear the Internet Explorer caches (Tools\Internet Options\General\Delete...)

Launch IE in no add-ons mode to test the issue, press Win+R, then copy 

iexplore.exe -extoff

to the Run box, Enter.

Or just reset IE (Pleaes note that you will lose some IE settings)

Thanks XP ROCKS.

I've placed a post there about the issue.

Nope that's not an answer I'm going to pursue.

This is IE 10 and IE 11 on Win 8.1 and 7 according to my latest research.  See post at WU site. 

Killing caches, is generally in my view, an act of desperation, and in my experience (given that I check event logs etc) has always been of no use.

This problem is pretty bad and could potentially destroy my machine.  I don't need shotgun, maybe it will work solutions, I need something based on insight.

If there is no fine grained control and restoration of absolutely anything, if I want, this cache clearing is, in my view, simply bad design.

I've altered my Facebook logon links and am considering making the domain inaccessible.

Hi MikeGale,

What about other troubleshooting steps? Regarding to the Windows Updates, to find out whether this issue is caused by the latest updates, we can return the system to that specific restore point which is created before installing the updates. System will usually automatically creates a system restore point before installing updates.

As in the original post, my idea here is to report this to a product development team.

I want such a team to be aware that browsers (after that last update) are doing things which shouldn't happen.

Potentially this is exploitable by malware.

I don't currently want to spend the time (or need to) on my own systems.

Hi MikeGale,

Got it. Thanks for your support.

Wish you a good day.

I've got this fixed now.

After a few days I noticed some additional problems, this time with lesser used email accounts.  These connect on port 995 securely and were failing.

That immediately made me think SChannel and that proved to be the case.

Some notes about that:

  • I altered my Crypto Suites some time ago.  This used the Group Policy editor, which unfortunately limits the size of registry settings to 1023 characters.  I needed to trim my ideal list to fit that but it worked, so I stuck with it.  I presume that SChannel was adding some suites (it still does) and those were removed in the update.  The added suites presumably included some I was forced to throw out.
  • This time I reset the crypto suites directly in the registry, with one of my original lists.  (PowerShell script.)  This fixed the issue.
  • If you check the suites offered by the browser these include some that you didn't list, that's not desirable, but at least you have some control (using SChannel) unlike the other approaches that infest our browsers.
  • Facebook appears to have a suite that I was requesting when it failed so no idea what it was doing, but it was fatal and knocked out the OS.  (NOTE:  I didn't wait for ever when the OS went belly up.)
  • I didn't find a list of suites supported by my end points of interest and needed to use TLS scanners (SSLLabs has an online tool which is good for checking servers) and inspect the TLS handshakes to be sure of what was going on.
  • Changes to your crypto suites need a reboot to take effect, so troubleshooting is not for the faint of heart.
  • The OS obviously shouldn't crash for a thing like this, so the recent patches to SChannel (and whatever) have a flaw.  I've done more than my bit on this, but if anybody who actually has contact with the team reads this, please let them know.

I still recommend taking charge of your own security, to some degree, including throwing out undesirable crypto suites, despite having gone through this rubbish.
