If that doesn??™t
help, or if your mouse is unavailable, open the Registry Editor,
navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows
NT\CurrentVersion\TaskManager and delete the TaskManager
key.
To find the program to close, sort the list. You can sort the list alphabetically
by filename (e.g., explorer.exe for Windows Explorer) by clicking the
Image Name column header. Or, sort by application title by clicking the
Description header.
But for most hung applications??”also known as ???frozen??? or ???locked up?????”
it??™ll be most entertaining to sort by exactly how busy the program is. Click
the CPU column header twice (so its little arrow is pointing down) to sort by
processor usage (a percentage from 0 to 99), and the crashed program will
usually leap to the top of the list. For instance, if Windows Explorer has
crashed??”unfortunately, such a common occurrence in Vista that a new
term was invented for it, explained in ???Green Ribbon of Death,??? later in this
chapter??”its CPU usage will usually be in the high 80s!
Just highlight the program in the list and click End Process. Only after you
do this will you be able to reopen the application.
Vista comes with another tool you can use to examine the
running processes: just open Windows Defender in Control
Panel, click the Tools button at the top of the window, and
then click the Software Explorer link. From the Category
list, choose Currently Running Programs, and then select
any task in the list to see its details on the right.
