Hi All,
I have read where some users have already upgraded to this version (1903) without reported incidents. I have not had the same luck or experience. On 3 laptops and a studio tower I performed the upgrade to 1903 and on all 3 I ran Latency Monitor to do an initial look at whether there was any change in the latency readings. They were a little higher than on the previous version but seemed stable for 3 or 4 minutes of testing on the first laptop so I thought all was well and upgraded the rest of the machines. Upon testing the tower it became apparent right away that there were DPC spikes occurring that were causing pops and glitches that were not there before. I ran the latency monitor for a longer period on all devices and discovered that there were random spikes all being caused by ntoskrnl.exe. Some spikes were as many as 8 minutes apart! This had never occurred before on any install so off to the net I go to see if anyone else had the problem and low and behold many people have had the same issue since this latest release. Luckily Win 10 allows for version rollback and so I rolled back to version 1803, retested all of the machines and presto, back in business. As of today this is not affecting everyone and is not a solved issue as far as MS through any patches etc for those that are having this trouble. If anyone else has some had some experience with this problem (I think it’s a newly introduced bug) Please post here with any fixes or possible tests or things I may have missed.
Thanks!
Dave
