Problem:
The afternoon computer suddenly went wrong, then the local MAVEN repository jar update is not down, so clean down. Re-open the folder into the disk no problem.
But clicking on "Computer" is jammed. See the error message is APPHANGB1.
Solve:
Baidu out of all kinds of unreliable, what the 360 scan, re-install the system and the like.
Think of a simple command: Sfc/scannow
Ran out and found no real system files.
That estimate is another problem, such as: "I have not shut down a lot of days, at least extended the national day." So, a shutdown restart may be effective without viruses or missing system files.

Accidental Discovery Small secret: Originally thought to shut down the machine, look at the cell phone, found that the phone is full of electricity, so the USB cable from the computer pulled down.
At this time found the computer to use, has not yet restarted it.
