Use Task Manager for Troubleshooting Windows 7
To use Task Manager to diagnose and troubleshoot Windows:
1. Right-click the taskbar and choose Start Task Manager.
2. Examine the Applications tab. If any application displays a status of Not Responding, select the application and click End Process. When prompted, click End process to close the application.
3. Select the Processes tab. You can click any of the column headings to sort the list of processes by that parameter. For example, to sort the list of processes in descending order by processor utilization, click the CPU column heading twice. (By default, the ﬁrst click of the column heading sorts the list in ascending order.) If necessary, select a process and click End Process to force it to close. Click End process to conﬁrm.
4. On the Services tab, view all the services that are currently running in the background.
Tips: Click the Services button at the bottom of the dialog box to start or stop other services.
5. On the Performance tab, use the information displayed to evaluate the computer’s performance. Key statistics on this page include:
- CPU Usage. The current CPU utilization on the computer.
- CPU Usage History. The recent history of CPU utilization on the computer.
- Memory. The amount of RAM memory in use (in MB). If this is particularly high, consider closing some of the applications that you are not using currently.
- Physical Memory Usage History. The recent history of physical memory usage.
- Physical Memory (MB). The amount of physical RAM installed in the computer. Available indicates the amount of RAM that is available for use by applications and data.
- Kernel Memory (MB). The amount of memory in use by the operating system and its device drivers. Paged indicates the amount of RAM currently occupied by Windows that it can swap to the paging ﬁle if necessary. Nonpaged indicates the amount of RAM containing the Windows operating system that can’t be swapped out to disk.
- System indicates the number of processes that are currently running and the system Up Time.
6. On the Networking tab, use the statistics displayed to determine the workload generated by network traffic. If the traffic is excessive, consider upgrading to a faster network card.
7. On the Users tab, if it appears, review the list of connected users and whether their status is active or idle. If necessary, you can use this page to disconnect or force a logoff of users.
Tips: This procedure is written to suit Windows 7. However, the same procedure can be followed with minor alterations to troubleshoot Windows XP as well.
