My experience :
For various problems I decided to reinstall my Windows 10 x64 cleanly.
Before reinstalling my Windows, Corsair LINK 4.8.3.8 and 4.9.0.57 were not working.
After reinstalling my Windows 10 (Befor Creator Update) I installed very quickly Corsair LINK 4.8.3.8. It operated for about 48 hours. :grand sourire:
Then the bug came back.
After installing hardware in my PC, installing software, modifying the Bios of the Motherboard !!!!! ?? I do not know.
So I returned to Corsair LINK 4.7.0.77 and this version works.
Unfortunately, I am unable to say when Corsair LINK 4.8.3.8 stopped working. It was running on a fresh installation of my Windows 10 x64.
