I've started having a stutter issue with MC18 (ironic because I switched from Foobar for the same reason). Other than video playback, MC18 has worked very well 'til about a month or two ago.
The changes to my PC I can think of: 1) I connected to the 'net after having been offline for most of the past 3 years; 2) I added Malwarebytes for 'net-related problems; and 3) I installed Pono Music World - which can create some weird behavior if MC18 is running at the same time.
Any one else experience something like this? How did you remedy it?

Disable real-time protection in your antimalware software. Then run JRMC.
If problem goes away, you've found it.
If problem does not go away, disable your network adapter in the control panel under system-> device manager.
If problem goes away, you've found it.
If problem has not gone away yet, it's not a network adapter issue OR AV software issue and it's something else.
A few times I was getting dropouts and very high latencies because of a goofed network driver. Not old version, just driver that becomes goofed and needed to be reinstalled a few times. It has not done this for quite some time, so something I was doing (or other software) was goofing it.
Download this. It's good for trouble shooting latency issues.

One of my challenges is that the problem is intermittent. I've been resolving the issue by stopping and resuming playback - not even restarting JRMC. But I will see, next time it happens, if I can leave JRMC running while I disable MWB.
Maybe I need to either go back to a "sneaker net" system or remove MWB and just live with the consequences of malware. It wouldn't be the end of the world to re-image as I don't have many programs loaded.
The intermittent problems can be the worst! The worst for me is when they happen often enough that I can't ignore them but not often enough to have a real chance of finding them. Reducing buffer sizes is a way to make the problems happen more frequently, possibly making diagnosis easier.
One way to get more information on Windows is to use the task manager to look at various processes, especially system processes. Look at CPU utilization, reads and writes, memory size, page faults. Get a feel for what the numbers look like when things are running well so that the problem items will be more visible when you hear glitches.
The DPC latency is another tool. You can try to correlate its behavior with glitches, and if you see this correlation then its a good bet that you have a driver problem. Disable various drivers and see what happens.

That should get me started, hopefully on the road to a remedy.
Yes, Tony has a great recommendation here.
For really stubborn glitches, you sometimes need to look at more detailed information on individual processes in real time. You go to the Task Manager and view all processes at once, and you can add or remove different metrics from the various columns of data provided.
Useful ones already showing are CPU utilization.
While in task manager if you go to "View" and then "Select Columns", add PF, PF Delta and all starting with "I/O".
Watch all the processes live and breathe - and perhaps notice corollary between a specific process and dropouts.
If you can figure out what the process is, you're almost there. If it's a specific program or driver it can be an easy fix. If it's a system process like csrss.exe it can be more difficult to track down.

I'm suspicious of all AV software. It degrades system performance in at least three ways: First, when it is doing downloads of new profiles and second when active protection is enabled and all input/output to the system is being intercepted and third, when it is doing an active scan of the entire system. In some cases these effects may be reduced or avoided by disabling the offending features while listening to music, but this is far from guaranteed. With some AV products a complete uninstall may be required to restore original performance. With the free Windows version for Windows 7, there is usually no effect on audio performance, but on occasion that is not the case and there doesn't seem to be any way of disabling the interference when it is happenning other than waiting for a half-hour or so for the interference to pass.
The usual way to reduce clicks and stutters is to increase buffer sizing and disable power management software (especially processor related). Unfortunately, in many cases using larger buffer sizes will reduce sound quality, so there are tradeoffs.
