Enabling TLS 1.1/1.2 support in Vista's Internet Explorer 9


Recommended Posts

Posted

 As all of you Vista users surely know, IE9 is the last version of the MS supplied browser that can be installed on that OS.
It has several prerequisites, notably KB948465 (SP2 for Vista SP1), KB971512 (Windows Graphics, Imaging, and XPS Library) and KB2117917 (Platform update supplement for Windows Vista); you can read more here.

 MS had continued patching security vulnerabilities in IE9 on Vista SP2 via "Cumulative Security Updates for Internet Explorer 9 on Windows Vista SP2" up until Vista's EOL on April 11th of this year (update KB4014661).

 MS will continue patching IE9 on Windows Server 2008 SP2 (as, again, it's the last version installable there, too) until that product reaches its (Extended Support) EOL in 2020. If you have been following our Server 2008 Updates on Windows Vista thread, then you should have already installed follow-ups KB4018271 (May 2017), KB4021558 (June 2017) and KB4025252 (July 2017). For the rest of this post I'll assume your Vista SP2 OS (ergo IE9 copy) is fully updated even with post EOL updates intended for WS2008SP2; e.g. on my setup (Vista SP2 Home Premium 32bit), "About Internet Explorer" looks like:

AboutIE9.jpg.08a136feaad2dcbe5246eefd1e7fedaa.jpg

 For those of you out there with an intention to using IE9 as your main browser on Vista, sadly, you'd have come to the conclusion it's only half-usable currently, at best; this is a result of:

1. Most modern sites have removed support for IE9 completely, via UA string sniffing:

YT-IE9.jpg.8b71d583ed2c55b93e2f2152ee5f4425.jpg

Somes sites (like Youtube) offer a workaround, for others it may be necessary to spoof the actual UA string as one from a later OS+IE version (e.g. via the "Set UA String" IE addon).

2. Many sites have moved to recent web design, so they don't render correctly (if at all) in IE9, even in "Compatibility View" (well, actually, this is to be expected; CV means the site was optimised for IE8-); FWIW, even MS pages don't display correctly now in IE9 :angry:.

3. A third scenario I find quite irritating is that many sites fail to load at all in IE9 if they use the HTTPS protocol; with the recent move of many major sites to the more secure, encrypted, HTTPS, "allegedly" to increase user privacy and security, I found the list of "secure" sites not opening in IE9 growing at a high rate; of course there's always Firefox, but it's IE9 we're discussing here... 

IE9-https.jpg.b7f18f8d438e8fea196673a8d2a467ba.jpg

Upon investigation, I discovered this is due to IE9 on Vista only supporting TLS protocol v1.0; this is considered by today's standards no longer secure enough, so many sites using HTTPS have moved to the more secure versions 1.1, 1.2, even to 1.3!

 Fortunately, a recent MS update (intended for the WS2008SP2 OS) can be applied on Vista SP2 that will implement TLS 1.1/1.2 support on Vista's IE9, too! :); I have spoken about this important update here.

1. Install then KB4019276

2. Reboot the Vista machine

3. After restart, launch the Registry Editor (regedit), preferably as Administrator.

4. Navigate to

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\AdvancedOptions\CRYPTO\TLS1.1

5. Delete the "OSVersion"="3.6.1.0.0" subkey; BTW, I don't know which WinOS that string refers to (Win6.1=Win7)

6. Navigate to

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\AdvancedOptions\CRYPTO\TLS1.2

7. Again, delete the "OSVersion"="3.6.1.0.0" subkey. Exit Registry Editor.

8. Launch IE9; Tools -> Internet Options -> Advanced tab -> Scroll all the way down to "Security":

IE9_VistaSP2_AdvancedOptions.thumb.jpg.8c032ea1ae8ed0c374cdc35e8a5b2bd8.jpg

Prior to KB4019276 and registry manipulations, only "Use TLS 1.0" had been available on Vista; you should have already unchecked the older "Use SSL 2.0/3.0" options, to avoid being targeted by "POODLE" attacks; uncheck "Use TLS 1.0" (optionally also "Use TLS 1.1") and check "Use TLS 1.2".

9. Click Apply, OK, then exit IE9.

10. Upon restarting IE9, you'll find you can now visit all those sites that previously would not load due to unsupported TLS protocols:

IE9-TLS12-Success.jpg.f9dde9e4589a16e5acd5e540fc767407.jpg

10. You can verify further that indeed 1.2 is being used during server-client negotiations via specialised sites or via IE9's native GUI:

IE9_TLS-1.2_VistaSP2_2.jpg.115d319bc6a8eb69f2102fbd0f411e33.jpg

I honestly hope you'll find my post to be of value; enjoy your more secure (than ever before?) Vista OS! :wub:

 Original post is about implementing TLS 1.1/1.2 support to IE9; it will allow for opening HTTPS websites that were previously inaccessible to IE9, because it would go as far as TLS 1.0.

 Sadly, the recent MS update has nothing to do with IE9's rendering engine, which is what's used to properly display (render) a loaded webpage -_-. For sites that do open but don't display correctly (and/or are not fully functional) you'll have to use another, more modern, browser that supports more recent Javascript and CSS code needed to render them correctly; apologies, but I'm not an expert in HTML and web design, so my terminology might be somewhat off, but I think you still get the picture (... or lack of it, if it fails to render in IE9 ! :P ).

 Please have a read of this older forum thread ; WS 2008 SP2 is already inside Extended Support (i.e. no new features, only security updates issued for it), so I was pleasantly surprised by KB4019276 which, depending on how you look at it, could be considered as a new OS feature; OTOH, it can simply fall inside the "security" category, since it improves the "security" protocols used when accessing HTTPS web places...

 I don't think that MS will issue any future updates in the remaining 2.5 years (till WS 2008 SP2 becomes EOL) that would enable an upgrade of IE9's layout engine - security: YES, they are still catering for that; functionality: THEY SIMPLY DON'T CARE; else they would've upgraded their own browser to IE10 or IE11 (possibly after a Vista/WS 2008 SP3 and/or a second Platform Update...).

Excellent post, VistaLover!

Really appreciate it, especially the Reg Edits, never would have known about them. Going to implement this in a few days time.

no sorry hapxhapx, you can not use the 2929781, 3161639 & 3042058 patches under Vista as those patches require Win7 (Server 2008 R2) or higher and will fail to install saying they're "not applicable to your computer".  MS did not make any of those patches for Vista/Server 2008 R0 SP2.

note to VistaLover (OP): the KB4019276 updates have been revised mid-November 2017 and there's also a KB4019276 patch available for POSReady 2009 users (ah for those still using XP).  Download & install the "revised" KB4019276 patches, installing them on top of the older version.

The KB4019276 update has been superseded / replaced by KB4056564 security update for Server 2008 (download here) so KB4019276 is no longer needed

For Vista/Server 2008. For POSReady 2009, KB4056564 should be used in addition to KB4019276, which is not superseded for the XP platform.

Hi everyone, I have windows vista home premium 32 bit and from a few weeks I can no longer receive certified mail (PEC) because the TLS 1.0 and 1.1 protocols have been blocked. Is there the possibility of implementing the TLS 1.2 protocol on outlook in windows vista?

 

Thanks

Welcome to MSFN resistor83. If you happen to have Outlook 2003, then the procedure described earlier in this thread is worth a try because 2003 used Internet Explorer's rendering engine. However it seems more likely that you have Outlook 2007, which used Microsoft Word's rendering engine and is therefore rather OT here. Perhaps Microsoft has added TLS 1.2 support for Office 2010, which hasn't quite reached EOL.

Since this thread has been resurrected, I'll mention that there has been some discussion beginning here that VistaLover's instructions are insufficient for Vista x64.

Ciao @resistor83 :) ; first thing I needed to do was get acquainted with PEC e-mail, since it's not used over here :P ; the following two links proved helpful:

https://en.wikipedia.org/wiki/Certified_email

https://vademecumitalia.com/pec-what-is-it-why-should-you-need-a-pec-address-and-how-to-get-one/

Now, I would strongly advise you to implement TLS 1.1/1.2 on your machine, regardless; probably better use the newer MS update, as per @erpdude8 :

I can't see any way it could harm your existing setup; BTW, you did not say anything regarding Windows Updates in your system (only official Vista SP2 ones, till Vista EOL?) ... :dubbio:

You specifically asked about Microsoft Outlook (part of Microsoft Office Suite), but, again, as pointed out by @Vistapocalypse, you neglected to tell about the used version...

I am using myself the native e-mail client under Vista, Windows Mail, which, AFAIK, uses IE9's internet settings - I just checked the headers in the source of a gmail e-mail I received recently and I can spot the following (some parts obscured for privacy):

Received: from mail-yw1-fxx.google.com (mail-yw1-fxx.google.com [209.85.xxx.xx]) by MX-IN-05.xxxxxxxx.gr (8.15.2/8.15.2) with ESMTPS id x8TKAo60027571 (version=TLSv1.2 cipher=AES256-GCM-SHA384 bits=256 verify=NOT)

so I believe I can receive e-mails over TLS 1.2; but, of course, as detailed in this thread, IE9 supports only a limited number of TLS 1.2 cypher suites... :(

Another solution for you to try on Vista would be the latest supported version of Thunderbird (52.9.1?) ...

As for Microsoft Outlook, @Vistapocalypse is probably right; versions 2007 and 2010 use the WinHTTP library to connect to servers; Windows applications using WinHTTP on WinOSes < 10 can't normally use TLS 1.1/1.2, even if these protocols are enabled system-wide in the SChannel library, because WinHTTP is hard-coded to use only TLS 1.0. Mom (!) Microsoft decided to not mitigate this under Windows Vista (and Windows Server 2008) SP2, but did so for its Win7+ children (!) - Thanks M$! :realmad:

https://support.microsoft.com/en-us/help/3140245/update-to-enable-tls-1-1-and-tls-1-2-as-default-secure-protocols-in-wi

Quote

This can allow certain applications that were built to use the WinHTTP default flag to be able to leverage the newer TLS 1.2 or TLS 1.1 protocols natively without any need for updates to the application.

This is the case for some Microsoft Office applications when they open documents from a SharePoint library or a Web Folder, IP-HTTPS tunnels for DirectAccess connectivity, and other applications by using technologies such as WebClient by using WebDav, WinRM, and others.

Installation of that update should be followed by manually creating some registry keys, as instructed in the KB article; most sadly, an equivalent Vista/WS2008 update was NEVER released :realmad: ...
