Object Library Not Registered When Adding Windows Common Controls 6.0

On 32-bit machines:

cd C:\Windows\System32
regsvr32 mscomctl.ocx
regtlib msdatsrc.tlb

or on 64 bit machines:

cd C:\Windows\SysWOW64
regsvr32 mscomctl.ocx
regtlib msdatsrc.tlb

These need to be run as administrator.

I can confirm that this is not fixable by unregistering and registering the MSCOMCTRL.OCX like before. I have been trying to pin down which update is the source of the problem and it looks like it's either IE10 or IE10 in combination with some other update that's causing the problem. If I can get more time to invest in this I'll update my post but in the meantime uninstalling IE10 resolves the issue.
