Windows 10

Fix Windows 10 Update Failures, e.g. Error 0x800f081f

Run Command Prompt or PowerShell  as administrator and enter the following commands to repair Windows system files. Once complete reboot and try running the update again.

DISM /Online /Cleanup-image /RestoreHealth

SFC /Scannow

DISM (Deployment Image Servicing and Management) manages both Windows Online and Offline Images and repairs system files

  • /Online switch instructs DISM to target the running Operating System instead of an offline Windows image (.wim) file or virtual hard disk (.vhd or .vhdx)
  • /Cleanup-Image switch performs cleanup and recovery operations on the running Operating System
  • /Restorehealth switch scans the running Operating System for corrupt files and attempts to fix them

SFC (System File Checker)

  • /Scannow will scan all protected system files, and replace corrupted files with a cached copy that is located in a compressed folder at %WinDir%\System32\dllcache

The above procedure also fixes Windows Defrag not running properly due to corrupt system files.

Disable Cortana in Windows 10 AU 2016

For reasons only known to Microsoft since the AU update you can no longer disable it from the desktop. However you can make the following registry change to work round this.

Press Windows+R and run “regedit” and navigate to the following key:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Windows Search

If you don’t see a “Windows Search” below the Windows folder, right-click the Windows folder and select New > Key and name it “Windows Search”. Right-click the “Windows Search” key (folder) and select New > DWORD (32-bit) Value. Name the value “AllowCortana”. This should automatically be set the value to 0. If not set it to 0. A zero value disables Cortana. You can now close the registry editor. The change may immediately take effect.  If not sign out and back in or restart your computer to implement the change.

Note a (default) subkey value 0 is automatically created under “Windows Search”.  Don’t worry about this.

To enable Cortana set “AllowCortana” to 1.
