Windows upgrade to 1607 after the operation of a very lag solution

CPU I5, Solid state 128g,win7 Master System, WIN10 and WIN7 are all installed on the SSD.

Before the upgrade, the operation is very smooth, so that the home of the antique computer also changed solid, the system for WIN10. Since the upgrade of 1607 after this problem appeared, into the desktop is quite fast, but one into the desktop, the operation of what things did not respond, such as the response came out of the dodo prominent to a large pile, let people are very annoyed, but the home of the computer after the upgrade nothing, very silent, is the problem of driving, consider not to reload, Office computer has a few software is very big, installation is very troublesome, so try not to walk reinstall this road, disable services, Startup items, Quick Start online most of the solutions have been tried, useless! Today in the online blind stroll, see a post, tried, and really useful, finally solved the problem of this headache. The problem is that when you use the Storahci.sys driver in some AHCI mode, it may cause individual SSDs to fail the correct input/output operation in the "Information signal Interruption" (MSI) mode, which is the case with Microsoft's Storahci.sys driver and SSD firmware compatibility. , I hope the next upgrade to Microsoft can solve this problem, the final performance of this problem is the system stalled, and the Task Manager disk occupancy rate is displayed as 100%. Of course the solution is also simple, just close it in regedit (MSI Mode). Say less nonsense, share.
