I would recommend to stay with the current version of Windows® 10 that you have installed. Now, when it comes to the Windows 10 1511 version, there has been some issues reported, here you can get more information about this issues Issue with Windows 10 Autumn Update.
If your current version works I would recommend to leave it until there is more information about the new Windows 10 version.
if you haven't done so yet, use the Microsoft provided tool (https://support.microsoft.com/en-us/kb/3073930 ) and it will let you "hide" the 1511, 10586 update. then all other updates will work normally.
Ok finally got the update to work. Again ICS came with W10 preinstalled. I reset the ICS via F8 and wiped everything to original. I updated the BIOS to 0031. Installed the 2 new drivers for Wireless and Bluetooth (12/7) for WIN 10. I then did a disk cleanup and wiped system files. Rebooted, then ran windows update which worked. My winver is "Version 1511 (OS Build 10586.29). The ICS is working great. I believe my problem was with the BIOS. I just the ICS at the end of Nov. It was built Aug 2015. The Bios was 0025.
