Just idling at a high frequency will not heat up a processor significantly unless it doing some kind of work (excluding gross hardware issues like a mis-installed cooler). You may be just running a few things, but from the utilization numbers in your screen shot your computer is clearly doing something. My experience with work laptops is there could be a number of background processes running that are managed by your IT department. YOU may only have a few things open, but there may be a lot more running in the background.
If you can remove the bottom cover on the laptop and inspect the fan/heatsinks they may be dirty and need cleaning. If you can do so without messing too much with company property that might be worth a go.
Your other option would be to talk with your companies IT department.
The problem isn't with the CPU boosting that high. it's supposed to. The problem is with the cooling system being improperly attached I think. no laptop CPU should EVER reach 90c when it's that far away from full load.
If the laptop is under warranty, get a replacement. If not, open it up and make sure the cooler is touching the CPU will good contact and replace the thermal paste.
