Simon:
Thank you for this information! I just spent 3 hours with Microsoft Level 2 Support Tech. He tried everything he could do to resolve this issue, to include a full reinstall of Windows 10 with updates. The Intell (R) Q35 Express Chipset Family Microsoft Corporation- WDDN 1.0) {Driver Management concluded the process to install driver igdlh.inf_x86_5a1c230d1529f473\igdlh.inf for Device Instance ID PCI\VEN_8086&DEV_29B2&SUBSYS_303817AA&REV_02\3&2ACF1E9&0&10 with the following status: 0x0},is not compatible with Window's 10. I guess 4 year old machines don't get supported! The Lenovo Support Page is a joke. They have no drivers listed for this computer on the Driver Update page for Windows 10 (I am running a M57p Desktop (Think Center Machine type 6073A-14) I know it was made in 2011, and upgraded from Vista to Windows7 Home Premium editions(I got it from Tiger Direct just off a 2-year lease, and was refurbished). I then upgraded it to Windows 10. Every thing worked Great until the update last Week, and I started having issues with Outlook, getting the error message as above except for 32 bit. I guess I can use Edge for my Outlook instead of IE-11. I will try and get a Windows 10 Driver from Lenovo, but the computer is out of warranty so I am sure they will want a hefty fee.
