'micro stutters' [cbs log included]

Sorry, yes you are on the latest build, there should also be a number after the 10586, mine is 10586.218. You may still have one of the smaller updates to complete. The last one was three weeks ago - KB3147458.

Here is a link with more information: KB3147458 Cumulative Update build 10586.21 for Windows 10 Version 1511

One of the improvements was video playback.

Ok now we know you are on the latest version (note: you should update your specs on this site to avoid future confusion) there are a number of threads that have already suggested a number of fixes for stuttering. Try this one and work through the various suggestions.

Windows 10 Stuttering / Freeze
