-
How can you end a task in Task Manager?
-
Right-click the process and select End task to stop it.
-
What is the function of the Details tab in Task Manager?
-
The Details tab provides more detailed information about running processes, including linked background services.
-
How can you change the priority of a running process in Task Manager?
-
Right-click the process, choose Set Priority, and select the desired priority level (e.g., Above Normal).
-
What is shown in the Performance tab in Task Manager?
-
The Performance tab displays detailed information about the system's CPU, memory, disk, network, and GPU usage.
-
What information does the CPU page in Task Manager provide?
-
It shows the number of CPU cores, logical processors, system uptime, and utilization statistics.
-
What does high CPU utilization over a sustained period indicate?
-
It suggests that the CPU is overloaded and may need more resources or fewer processes.
-
What information is provided on the GPU page in Task Manager?
-
It shows the amount of GPU memory available and how much the GPU is being used.
-
What is displayed on the Memory page in Task Manager?
-
It shows how much memory is in use, committed memory, and memory available for use, including paged and non-paged pool data.
-
What is the significance of high pagefile usage in memory monitoring?
-
High pagefile usage may indicate that the system is relying heavily on virtual memory, which could cause performance issues.
-
What does the Disk page in Task Manager show?
-
It shows the type and capacity of the disk, active time, response time, and read/write speeds.
-
What causes high disk utilization and slow response times?
-
Possible causes include slow HDDs, excessive paging, file/cache corruption, or faulty disks with bad sectors or blocks.
-
What information does the Network tab in Task Manager provide?
-
It shows send and receive throughput for network data and IP/MAC addresses.
-
What additional details are shown for Wi-Fi connections in Task Manager?
-
The Network tab for Wi-Fi shows the SSID (network name), connection type (802.11 standard), and signal strength.
-
What does the Users tab in Task Manager allow you to do?
-
It lets you view logged-in users, send messages, sign users out, and monitor the processes and resources each user is consuming.
-
What can be managed from the Startup tab in Task Manager?
-
You can disable programs that automatically run at startup and view the impact of these programs on boot times.
-
What does the Services tab in Task Manager monitor?
-
It monitors the state of all registered background processes (services), which run without user interaction and provide core OS functionality.
-
How can you manage services in Task Manager?
-
You can disable nonessential services, change their startup behavior (Manual or Disabled), and open the Services console for advanced options.
-
What is Resource Monitor (resmon.exe)?
-
Resource Monitor provides detailed monitoring of system resources, displaying graphs and key statistics like threads and page faults.
-
What does Performance Monitor (perfmon.msc) do?
-
Performance Monitor allows you to create real-time charts of system resources and log performance data for long-term analysis.
-
What are Data Collector Sets in Performance Monitor?
-
They are log files created in Performance Monitor to record system performance data over time for baseline analysis and troubleshooting.
-
What are Counter logs in Performance Monitor used for?
-
Counter logs collect statistics about system resources, such as CPU, memory, and disk usage, to assess system health.
-
What are Trace logs in Performance Monitor?
-
Trace logs collect detailed statistics about services and processes, providing more in-depth data than the Event Viewer.
-
What is the % Processor Time counter in Performance Monitor?
-
It measures the percentage of time the CPU is executing non-idle tasks. It should remain below 85% for sustained periods to avoid bottlenecks.
-
What is the % Disk Time counter in Performance Monitor?
-
It tracks how much time the disk is busy handling read/write requests. If it exceeds 85% for long periods, the disk may be overloaded.
-
What is the Available Bytes counter in Performance Monitor?
-
It shows the amount of free memory. It should not drop below 10% of total RAM, as lower values could indicate a memory leak.
-
What is the % Usage counter for the paging file in Performance Monitor?
-
It measures how much of the paging file is in use. High usage suggests the system may benefit from adding more RAM to reduce paging.
-
What is the purpose of the System Configuration Utility (msconfig.exe)?
-
It allows you to modify system boot settings for diagnostic purposes and to control which services and drivers load at startup.
-
What are the three startup modes in the General tab of the System Configuration Utility?
-
Normal startup, Diagnostic startup, and Selective startup.
-
What can be configured in the Boot tab of the System Configuration Utility?
-
You can change the default OS, set Safe Mode, configure boot options, and set the boot timeout value.
-
How can you log boot events using the System Configuration Utility?
-
By enabling boot logging, events will be saved to the file %SystemRoot%\ntbtlog.txt.
-
What does the Services tab in the System Configuration Utility allow you to do?
-
