You install and run a third-party 32-bit application named Application on your Windows 2000 Server computer. After several days, the application stops responding. You open Task Manager and find that the CPU usage is at 100 percent. The normal range of CPU usage on the server is from 20 percent to 30 percent You end the application. However, you see that the CPU on the server is still at 100 percent. Task Manager shows no other applications running. You then examine the Processes page in Task Manager and confirm that the Application.exe process is no longer running. You want to return the CPU usage to its normal range. What should you do?

The following notes refer to a traverse run by a tacheometer fitted with an anallactic lens, with constant 100 and staff held vertical. Line, Bearing, Vertical Angle, Staff Intercept -PQ, 30o 24′, + 5o 06′,1.875; QR, 300o 48′, + 3o 48′,1.445; RS, 226o 12′, − 2o 36′, 1.725 respectively. Find the length and bearing of SP.
The following are the staff readings given when the staff is held normal. The line of sight of instrument is placed at an angle +3024ꞌ. It being an anallactic lens, find the horizontal distance between staff and instrument station. Staff readings – 2.145 m, 1.925 m, 1.464 m.
Calculate the value of R.L for staff being vertical and possessing staff readings as follows 2.892, 2.234, 1.926. It being an anallactic lens possesses an instrumental height of 1.94 with R.L 102.34 m. Line of sight placed at an angle of 2042ꞌ.
