I noticed a minor issue after upgrading my 7-year old Lenovo ThinkPad to the Creators Update. In wandering through Device Manager to see what drivers may have been updated, I noticed that on occasion when I clicked on the "Driver" tab of a particular device, it would not respond for several seconds. Task Manager indicated that MMC.exe had jumped to the top of the CPU process column (below System Idle Process) and was using 5% to 6% of the CPU. I don't know if that had been occurring under previous releases. These are the computers specs:

Intel i7 Q720 @ 1.6 gHz
Seagate 500GB 7200RPM Hard Drive

No big deal. I was wondering if any one else had noticed something like that. It may be just the age of the PC.
