Managing Windows images and repairing the system?

Managing Windows images and repairing the system using the Command Prompt can be useful in various scenarios, especially when performing maintenance, deployment, or troubleshooting. Here are the key commands and steps:

1. Managing Windows images using DISM
2. Repairing the system with SFC
3. Fixing boot configuration and startup problems
4. Other useful tools:

1.) Managing Windows images using DISM

The DISM (Deployment Image Servicing and Management) tool is used to manage Windows images (e.g. install.wim or install.esd), maintain them or repair the current system.

DISM commands:

1. Check and repair system integrity:

dism /Online /Cleanup-Image /CheckHealth

Checks for any corruption in the image.

dism /Online /Cleanup-Image /ScanHealth

Scans for problems in the image.

dism /Online /Cleanup-Image /RestoreHealth

Repairs the Windows image using files from Windows Update or a provided source.

2. Mount and maintain a Windows image:

- Mount an image:

dism /Mount-Wim /WimFile:"Path\to\install.wim" /Index:1 /MountDir:"C:\Mount"

- Add a driver or component:

dism /Image:"C:\Mount" /Add-Driver /Driver:"Path\to\driver" /Recurse

- Unmount:

dism /Unmount-Wim /MountDir:"C:\Mount" /Commit

3. Extract files from an image:

dism /Export-Image /SourceImageFile:"Path\to\install.wim" /SourceIndex:1 /DestinationImageFile:"Path\to
new.wim" /Compress:max /CheckIntegrity

2.) Repairing the system with SFC

The SFC (System File Checker) tool is used to check and automatically repair corrupted or missing system files.

SFC command:

sfc /scannow

- Checks and repairs system files.

- If SFC finds problems that it cannot fix, DISM should be used first.

3.) Fixing boot configuration and startup problems

The bootrec and bcdedit commands can be used to repair startup problems.

Bootrec commands:

1. Repair MBR (Master Boot Record):

bootrec /FixMbr

2. Rewrite boot sector:

bootrec /FixBoot

3. Repair Boot Configuration Data (BCD):

bootrec /RebuildBcd

Edit BCD with bcdedit:

1. View boot entries:

bcdedit

2. Edit boot entries (e.g. change timeout):

bcdedit /timeout 30

4.) Other useful tools:

- CHKDSK: Checks and repairs hard drive errors.

chkdsk C: /f /r

- Network diagnostics with netsh:

netsh winsock reset

These tools and commands can be used to efficiently manage Windows images and troubleshoot system problems.
