We are today publishing our benchmark study on does temporary files and registry junk data slow down a Windows 10 computer. We test this with benchmarks on both virtual machines and with a real PC.
The testing shows that temporary files and registry junk can indeed slow down even a modern Windows 10 computer, and the effect can be noticeable.
