[SOLVED] Very high DPC and ISR by storport.sys and classpnp.sys. FIX: I moved the HDD from Sata3 port to Sata2 port.

Hmmmm..... too bad that the Windows Store itself doesn't work at all, or you could try visiting the Store to reinstall the apps from there.

It looks like you might be to the last two of the options.... create a new user, or the in-place reinstall.

Unfortunately, I haven't seen enough evidence yet to really know exactly why so many Windows 10 users are having issues with the Store and the Store apps.
(it's rather embarrassing for Microsoft, I would think ... that it is their own Apps that are behaving the worst!) I confess that I use very few of the Windows built in apps ... I generally uninstall a good portion of them right after I've installed Windows. Too bad, too, because I rather liked some of the older Windows built-in (not "Apps", but regular programs ... they just worked, and worked well.)

The link to the repair install guide is up in my previous post.

Hope things get better soon.
 
I thought this was about fixing classpnp.sys and storport.sys, not the nvlddmkm driver which is the easiest one to fix. All you have to do to fix nvlddmkm is to use interrupt affinity policy tool and set the pci bus for your gpu and your gpu to a different core other than core 0, then put your gpu in msi mode, from the msi utility v3 tool. Storport and classpnp is a whole different case and the title of this forum thread was storport and classpnp. Highly disappointed that it didn’t show any fixes for those 2 drivers.
