Just wanted to update.
Started have same problem of taskbar not skinning after reboot.
This time I had only re-installed Intel's Anti-Theft Service which is actually a McAfee product.
Right away I began to have problems not only with the taskbar, but other services were acting strange.
Intel's AT service encrypts everything, and who knows what else it does. There is a large list of things that gets installed.
Eventually as my system struggled (and I have plenty of ram and disc space), it would begin to corrupt and I would have to run "sfc /scannow" just to repair those files before the corruption spread to a full catastrophic system meltdown.
Windowblinds seems to have the most trouble with Intel's AT service, not sure how or why. I use CursorFX Plus without problems, and have tried Start8 and Decor8 the latter two were removed at the height of all the trouble, will try them again in a few days.
I did not notice any problems running Intel's AT service before I started using Windowblinds.
Now that Intel's AT Service is gone, everything is running smooth again like it should.
I enjoy using Windowblinds so the tradeoff isn't easily weighed.
