How to Do A "Clean Boot" With Powershell?

5 minutes read

To perform a clean boot with PowerShell, you can use the "msconfig" command to open the System Configuration tool. From there, you can choose the "Selective startup" option and uncheck the "Load startup items" checkbox. This will ensure that only essential system services and drivers are loaded during the boot process. Additionally, you can also disable third-party services and startup items using the "Services" and "Startup" tabs in the System Configuration tool. By following these steps, you can troubleshoot and isolate any issues with your system that may be caused by conflicting programs or services.


What is the best practice for troubleshooting system errors with a clean boot in PowerShell?

The best practice for troubleshooting system errors with a clean boot in PowerShell is to follow these steps:

  1. Open PowerShell as an administrator.
  2. Type "msconfig" and press Enter to open the System Configuration utility.
  3. Go to the "Services" tab and check the box that says "Hide all Microsoft services."
  4. Click on the "Disable all" button to disable all remaining services.
  5. Go to the "Startup" tab and click on the "Open Task Manager" link.
  6. Disable all startup items by right-clicking on each one and selecting "Disable."
  7. Close Task Manager and go back to the System Configuration utility. Click on "OK" to apply the changes and restart your computer.
  8. Once your computer has restarted, open PowerShell as an administrator again and test to see if the system error has been resolved.
  9. If the error is gone, you can start enabling services and startup items one by one to see which one is causing the issue.
  10. If the error persists, you may need to seek further assistance from a professional or contact the manufacturer of your computer or operating system for support.


What is the impact of a clean boot on system performance in PowerShell?

A clean boot in PowerShell can have a positive impact on system performance as it allows the operating system to start with a minimal set of drivers and startup programs. This can help to troubleshoot and isolate issues that may be causing the system to run slowly or perform poorly. By starting the system in a clean boot state, unnecessary processes and services are disabled, which can reduce the strain on system resources and improve overall performance. Additionally, a clean boot can help to identify any conflicts or compatibility issues with third-party software or drivers that may be causing performance issues.


How to disable unnecessary services during a clean boot using PowerShell?

To disable unnecessary services during a clean boot using PowerShell, follow these steps:

  1. Open PowerShell as an administrator.
  2. Run the following command to get a list of all services and their status: Get-Service | Format-Table -Property Name, Status
  3. Identify the services that are unnecessary and need to be disabled.
  4. Run the following command to stop a specific service: Stop-Service -Name "ServiceName" -Force
  5. Run the following command to disable a specific service: Set-Service -Name "ServiceName" -StartupType Disabled
  6. Repeat steps 4 and 5 for all the unnecessary services that need to be disabled.
  7. Restart your computer to apply the changes.
  8. After the computer has restarted, check if the unnecessary services are disabled by running the command in step 2 again.


By following these steps, you can effectively disable unnecessary services during a clean boot using PowerShell.


How to test system performance improvements after a clean boot with PowerShell?

  1. Open PowerShell as an administrator.
  2. Run the following command to perform a clean boot on your system: 
1

bcdedit /set {current} safeboot minimal


  1. Restart your computer to enter the clean boot mode.
  2. After the system has restarted, open PowerShell again as an administrator.
  3. Run the following command to check the system performance before making any performance improvements: 
1

Get-WmiObject Win32_PerfFormattedData_PerfOS_Processor | Select Name, PercentProcessorTime


  1. Make the necessary system performance improvements, such as updating drivers, disabling unnecessary startup programs, or increasing system memory.
  2. After making the improvements, open PowerShell and run the following command to check the system performance again: 
1

Get-WmiObject Win32_PerfFormattedData_PerfOS_Processor | Select Name, PercentProcessorTime


  1. Compare the performance metrics before and after the improvements to assess the impact of the changes.
  2. If desired, you can revert your system to normal boot mode by running the following command in PowerShell: 
1

bcdedit /deletevalue {current} safeboot



How to monitor system performance after performing a clean boot with PowerShell?

After performing a clean boot on your system with PowerShell, you can monitor system performance using the following steps:

  1. Open PowerShell as an administrator.
  2. Run the command "Get-Process" to view the list of currently running processes on your system. This will show you the CPU and memory usage of each process.
  3. Run the command "Get-WmiObject Win32_PerfFormattedData_PerfOS_Processor" to view CPU performance metrics such as usage percentage, idle time, and more.
  4. Run the command "Get-WmiObject Win32_PerfFormattedData_PerfOS_Memory" to view memory performance metrics such as available memory, page file usage, and more.
  5. Run the command "Get-WmiObject Win32_PerfFormattedData_PerfOS_System" to view system performance metrics such as context switches per second, system calls per second, and more.
  6. You can also use performance monitoring tools such as Performance Monitor (perfmon) or third-party monitoring tools to track system performance over time.


By following these steps, you can effectively monitor system performance after performing a clean boot with PowerShell.


What is the benefit of doing a clean boot in PowerShell before troubleshooting?

Doing a clean boot in PowerShell before troubleshooting can help eliminate potential software conflicts or issues that could be causing the problem you are trying to troubleshoot. By starting your computer with only the essential drivers and services running, you can determine if the issue is being caused by a third-party software or service that is not necessary for basic computer functionality. This can help you narrow down the cause of the problem and focus your troubleshooting efforts on the specific software or service that is causing the issue.
