new cis update causing explorer issues

I’ve been happily using cis for a few years now on my win7 64 system, and got thea popup yesterday that a new version was available.
After installibg however, i experienced severe explorer issues; new drives connected. caused explorr to hang, including disk management, and at that point network drives start hanging too.
Trying to shut down causes the system to get stuck at “logging off”

I managed to uninstall cis (took like 10m for some reason to even " validate" the uninstaller) and that fixed all issuesj

Maybe related to this bug:
