Repair the bug in Microsoft Access Database engine 2010
The KB4484126 and KB4484238 introduce a critical bug in Microsoft Access Database engine 2010.
On Windows Server 2012, IIS App Pools running Access MDB databases are constantly crashing with these KB installed.
Experiences on many production-level websites, running under 32-bit App Pools.
Once these KB's are removed, IIS App Pools stop crashing, and are back to a normal state.
The cure is worse than the CVE cause.
