BSOD after Windows 10 Update

I got the Blue Screen of Death after downloading an update. I've been trying to do a system restore but the C: option is grayed out and says:

You must enable system protection on this drive.

Recently I’ve opened the Command Prompt and it takes me to:

X:\windows\system32>

In which I’ve entered Rstrui.exe/offline:C:\windows=active

From there I can only select the E: (System) to do the system restore, but it ends in it being unsuccessful, stating:

System Restore failed while restoring the registry from the restore point. An unspecified error occurred during System Restore. (0x80070002)

I’m not sure where to go from here.

Summary from question:

I tried the “dism.exe...” command ... “Windows Resource Protection could not perform the requested operation.”

Windows is not running which means you cannot do a Repair Install.

So at this point, for a proper repair, back up all your data, favorites and email by starting in Safe Mode or Command to a USB Hard Drive connected to the system and reinstall Windows.

You can get the Windows 10 ISO for making a UBS Install Key from the Microsoft Media Creation Link:

The re-install will correct deficiencies, and update drivers. Then you can install software slowly to make sure everything is running.
