Confirming the same behavior in another Vista VM. Thus far we've been able to reproduce this using the stock Vista VMs provided by modern.ie, but ideally we should confirm this bug with a different setup just to be sure it's not an issue with the particular VM they distribute.
We should consider expanding the changes to bouncer made for bug 1233779 to include Vista as well due to this issue.
Probably, Jeremy, can you help here? Thanks
I believe https://support.microsoft.com/en-us/kb/2763674 is the likely culprit here.
It looks like Vista is Windows NT 6.0. It would be easy to add this to bouncer. Let's plan on doing this. Should we do an emergency push today or wait until after the holiday weekend?
Shall we start pinning Vista to sha1 builds as well?
Yes, thank you Jeremy, please do! Again, I guess our issue is that we can't differentiate easily between Vista users who have service pack 2 vs. those who don't. So for now we have to send them all to the sha-1 builds.
Jeremy, can you take this? I think it may be the last issue we have to deploy.
The work around has been deployed.
