Overview

Useful tools for when that got dang Windows just ain't acting right. 😤

DISM

  1. This is a quick scan and will determine if the image is repairable.
1DISM /Online /Cleanup-Image /ScanHealth
  1. This will check if there are any corruptions detected. Like the check health command, this will not repair any errors.
1DISM /Online /Cleanup-Image /CheckHealth
  1. If there are any corrupt or missing files after performing one of the scans mentioned above, you can repair them automatically. Your computer will need to be connected to the Internet for the files to be automatically restored.
1DISM /Online /Cleanup-Image /RestoreHealth

ISO

There are circumstances where

  1. Download a Windows ISO from here: https://www.microsoft.com/en-us/software-download/windows10
  2. Mount the ISO and navigate to sources and copy install.esd to a local directory.
  3. Open a command prompt and get the index of the correct image using:
1dism /Get-WimInfo /WimFile:install.esd
  1. Take note of the index, and convert install.esd to install.wim:
1dism /export-image /SourceImageFile:install.esd /SourceIndex:6 /DestinationImageFile:install.wim /Compress:max /CheckIntegrity

SFC

The "sfc /scannow" command is a Windows utility used to scan system files for integrity violations and repair any issues it finds. It stands for System File Checker and can help resolve issues with missing or corrupted system files. Running this command requires administrator privileges and may take several minutes to complete.

1sfc /scannow

DLL Hell

Visual Studio Runtime:

vc_redist.x64.exe

Permalink for latest supported x64 version. The X64 Redistributable package contains both ARM64 and X64 binaries. This package makes it easy to install required Visual C++ ARM64 binaries when the X64 Redistributable is installed on an ARM64 device.

Source

Re-register a single DLL file:

1regsvr32 "path & filename of DLL or OCX"

Re-register all DLL files:

1for %1 in (*.dll) do regsvr32 /s %1

Windows Apps

Reinstall and re-register all Windows apps for current account only:

1Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

Reinstall and re-register all Windows apps for all accounts:

1Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
