Running a DISM Scan

What is DISM?

DISM stands for Deployment Imaging Service and Management. It’s a tool built into Windows that helps fix issues with the system image. Think of it as a doctor for your computer’s operating system, checking for and healing any problems.

Steps to Run a DISM Scan

  1. Open Command Prompt as an administrator. You can do this by typing “cmd” in the search bar, right-clicking on Command Prompt, and selecting “Run as administrator.”
  2. In the Command Prompt window, type the following command and press Enter:
    dism /online /cleanup-image /restorehealth
  3. Wait for the scan to complete. This might take several minutes, so be patient.

Note: Make sure your computer is connected to the internet during the scan, as DISM may need to download files to fix issues.

Interpreting DISM Results

Once the scan is done, you’ll see a message indicating the results. Here are some common outcomes:

  • No component store corruption detected: Your system is in good shape.
  • The restore operation completed successfully: Issues were found and fixed.
  • Error messages: If you see any errors, you might need to run the scan again or seek further help.

Running a DISM scan is a simple yet powerful way to keep your Windows system healthy. If you encounter any issues, don’t hesitate to reach out to Omaha Computing Solutions for assistance.

Running an SFC Scan

What is SFC?

The System File Checker (SFC) is a handy tool in Windows that helps fix corrupted or missing system files. It’s like a doctor for your computer, making sure everything is in tip-top shape.

Steps to Run an SFC Scan

Running an SFC scan is pretty straightforward. Just follow these steps:

  1. Open the Command Prompt as an administrator. To do this, type “cmd” in the search bar, right-click on Command Prompt, and select “Run as administrator.”
  2. In the Command Prompt window, type sfc /scannow and press Enter.
  3. Wait for the scan to complete. This might take some time, so be patient.

Exploring Command Prompt and PowerShell

Differences Between Command Prompt and PowerShell

Command Prompt and PowerShell are both command-line tools in Windows, but they serve different purposes. Command Prompt is the older tool, primarily used for executing simple commands and running batch files. On the other hand, PowerShell is more advanced and designed for system administration tasks. It includes a scripting language and supports automation, making it a powerful tool for IT professionals.

Basic Commands to Know

Here are some basic commands you should know for both Command Prompt and PowerShell:

  • dir: Lists files and directories in the current directory.
  • cd: Changes the current directory.
  • copy: Copies files from one location to another.
  • move: Moves files from one location to another.
  • del: Deletes files.

For PowerShell, you can also use cmdlets like Get-Help to get information about other commands.

Advanced Uses and Benefits

PowerShell offers advanced features that can make your life easier. For example, you can use it to manage your SharePoint Online subscription in Office 365. This is done through the SharePoint Online Management Shell, which is a tool that contains a Windows PowerShell module. With PowerShell, you can automate repetitive tasks, manage system configurations, and even create complex scripts to handle multiple tasks at once.

Learning to use Command Prompt and PowerShell can give you a level of control and functionality beyond what the graphical user interface offers. It’s worth investing some time to get familiar with these tools.

Whether you’re troubleshooting issues or performing advanced configurations, these command-line tools are invaluable for any Windows user.

Customizing Your Taskbar

Accessing Taskbar Settings

To start customizing your taskbar, right-click on the taskbar itself and select “Taskbar settings”. This will open a new window where you can tweak various options to suit your needs.

Customization Options

Here are some of the key customization options available:

  • Auto-hide the taskbar: This option hides the taskbar when it’s not in use, giving you more screen space.
  • Combine taskbar buttons: You can choose to combine taskbar buttons when the taskbar is full, or never combine them at all.
  • Add or remove system icons: Decide which system icons you want to appear on the taskbar, such as the clock, volume, and network icons.

Improving Workflow with Taskbar Tweaks

Customizing your taskbar can significantly improve your workflow. For example, pinning frequently used apps to the taskbar allows for quick access. You can also rearrange the icons to keep your most important apps within easy reach.

A well-organized taskbar can make your daily tasks much smoother and more efficient. Take a few minutes to explore the settings and find what works best for you.
