Windows 10 extremely slow after one of the latest updates

A collegaue and I experience that our laptops have become extremely slow after one of the latest Windows 10 updates. Everything we do seems to stall a bit: Search in Visual Studio solution, open a file, open a new tab in Chrome, typing a bit fast in any kind of application, search for application in Windows, etc. The CPU, memory and disk usages are not anywhere near to 100 %. We both have a Asus Zenbook with the following stats:

Processor: Intel(R) Core(TM) i7-3517U CPU @ 1.90GHz, 2401 Mhz, 2 Core(s), 4 Logical Processor(s)

System Type: x64-based PC

Installed Physical Memory (RAM): 10.0 GB

System Model: UX32VD

Display Components: GeForce GT 620M, NVIDIA compatible (Driver version: 358.50) &
Intel(R) HD Graphics 4000 (Driver version: 10.18.10.4276)

Disk: Samsung SSD 840 PRO Series (See SSD Benchmark below)

It's just everything that has become slow.

Mine is upgraded from Windows 8.1, but my collegue's is a fresh install. But just to be clear: The computers have run fine with Windows 10 until recently.

Any ideas of what have gone wrong with the latest idea? Please tell me if you need more information about the computer and the Windows install.

EDIT: I have discovered, when the computer becomes slow, the CPU won't go above 41% on any of the cores.
