Known issues in this update
Symptom
Due to a defect in WLDAP32.DLL, applications that perform LDAP referral chasing can consume too many dynamic TCP ports (potentially exhausting them) after installing KB4025337 and KB4025341. Applications and roles known to make these referrals may include Outlook.exe, DFSR, and others.
Workaround
To work around the problem, restart services or applications that perform LDAP referral chasing to free TCP dynamic ports. A reboot will also free ports. For example, restarting Outlook will free ports used by that application.
Symptom
If restarting applications that perform LDAP referral chasing returns normal functionality on machines that installed KB4025337 and KB4025341, you may be experiencing this issue.
Workaround
To work around the problem for cluster computers hosting the DFSR service, place the virtual cluster object under the Computers container to avoid reaching the referral chasing search, which leads to the dynamic port leak.
Microsoft is working on a resolution and will provide an update in an upcoming release.

The new KB4034670 is supposed to fix up issues with the previous KB4034664 but comes with its own issues. That's not very impressive!
So you've installed KB4034664 should you bother with KB4034670 or just wait for the next rollup?

I installed both update preview..
THANKFULLY IT DID NOT BRICK MY PC!! lol
I thought my install went fine when I did it yesterday. Restart was fine also. History said successful. This morning when I turned it on, I got really worried as it continued the installation? Was @ 35% for 5 minutes and then went to 100% and stayed there for a least an hour, no HDD activity.
Dis-obeyed MS and restarted my computer, now hung @ 35% and stayed there for 30 minutes. Had chores to do so I left it on and returned 3 hours later. PHEW!! normal desktop, history did not change from yesterday. Made an image and will see what happens. Seems normal at present.
I'd like to know what happened to MS rolling all the past patches into the rollups? That was announced a year ago now.
From my testing - so far I've discovered one past update that's been incorporated into the rollups - a universal C runtime update.
At this rate, by the time they've incorporated a substantial amount of them, Windows 7 will have reached EOL! So, what's the point??
There's nothing important about this preview update, especially if you haven't had any issues with the August update 4034664. If you've installed that without problem then ignore the unchecked and optional preview update 4034670, it's just a standard preview update and those are only intended for professional users with test environments - hence their being unchecked and optional.
