Major problems with windows 1803 update.
All of my rigs use 570 or 580
After update. I can't get any rig to have more than 6 gpus attached, 10 out of 12 I can only get 5 gpus working.
Takes a very long time to initialize claymore miner.
If I try to go past 5 or 6 gpus claymore timesout/reset after 5 min.
Everything was working fine before the 1803 update with latest claymore and amd latest drivers
basically i have the same problem as

It's not a good idea to update to a new major Windows feature update as soon as it's released, since they often break compatibility with drivers and programs. It's better to wait until the mainstream build is released. The current v1803 build is essentially a beta preview build so that vendors can update drivers and software to be compatible with the new build.
In the Windows 10 Pro Group Policy Editor you can set Windows to only upgrade to feature updates when there enter a final release build.
Enable this policy to specify the level of Preview Build or Feature Updates to receive, and when.
* Preview Build - Fast: Devices set to this level will be the first to receive new builds of Windows with features not yet available to the general public. Select Fast to participate in identifying and reporting issues to Microsoft, and provide suggestions on new functionality.
* Preview Build - Slow: Devices set to this level receive new builds of Windows before they are available to the general public, but at a slower cadence than those set to Fast, and with changes and fixes identified in earlier builds.
* Release Preview: Receive builds of Windows just before Microsoft releases them to the general public.
* Semi-Annual Channel (Targeted): Receive feature updates when they are released to the general public.
* Semi-Annual Channel: Feature updates will arrive when they are declared Semi-Annual Channel. This usually occurs about 4 months after Semi-Annual Channel (Targeted), indicating that Microsoft, Independent Software Vendors (ISVs), partners and customer believe that the release is ready for broad deployment.
gpedit ==> Administrative Templates ==> Windows Components ==> Windows Updates ==> Windows Update for Business ==> Select when Preview Builds and Feature Updates are Received ==> Set to 'enabled' and in the drop down select 'Semi-Annual Channel'.
