I just updated my Windows 10 Pro / amd64 machine to "Evaluation Copy Build 17713.rs5_releae. 180706-1551". Actually, I did this on two different machines. In both cases, the following problems occurred.
I have "ClipCache Pro" installed on my machines. It stores its database in the user's document folder. In my case, "C:\Users\Gerard\Documents\ClipCache". After upgrading, this folder, the entire "Documents" folder was emptied. Why?
I run the "Intel(R) Rapid Storage Technology" on one machine to handle the RAID 5 configuration. The program was corrupted after the upgrade and I had to redownload and install it. Again, why?
I am only now starting to find other files apparently missing or corrupted. I think that there is something seriously wrong with this upgrade and Microsoft should look into it more closely.
