I have an Inspiron 3521 which is less than 2 years old. My hard drive is a Seagate 500 GB running Windows 8.
While shutting down, a message 'Task Host Window is running background tasks' is being displayed.
I was asked to Force Shut Down or to close the process by clicking cancel.
I already tried Force Shut Down(Shut Down Anyway) and my PC behavior was adversely affected.
I conducted a Hardware Scan on Dell Support and the results said their were 8 bad sectors (I believe that was the correct terminology) found and then I performed an advance scan. Result found critical errors both with the Targeted Read Test and the SMART Short Self Test. Both failed. It was recommended to replace my hard drive which is not a possibility at this time.
Hot fixes are made available for Windows 7 bot not for Windows 8.
I hope a solution and Thanks.
