Return question - WHY?
Why upgrade or update windows? especialy on mining rig? It works good - leave it as it is!
Updates wont give you hasgrate increase. Honestly speaking you wont see any difference at all. You have about 70% of seeng new problems instead of any improvements..
Trying Clay 10.2 will see how it goes. 10.1 was highly unstable and unusable..
Yeah agreed, however you also don't want to leave any OS vulnerabilities open on your always connected machine.
I am using 10.2, same issue older versions so I do not believe that it has anything to do with a particular release.
At this point, I am suspecting an issue with TeamViewer since somebody else on the forum has reported a similar issue.
I got everything working by plugging in a switched off monitor so its all good at the moment, however I will try disabling TeamViewer next time I am on site (the miner is in a remote location) to see if that makes any difference.
