To force an early Windows 10 upgrade from Windows 7 or Windows 8, follow one of the two methods below. You will need administrative privileges to run the update.

1. Locate the registry key:
   • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\OSUpgrade
2. Create a new DWORD (32-bit) Value with the name AllowOSUpgrade, and set the value to 1.
3. Run “Check for Updates” in Windows Update

1. Remove all files in C:\Windows\SoftwareDistribution\Download
   • It seems Windows 10 won’t install with existing pending updates.
   • These files are temporary storage for Windows Update so it’s okay to delete them
2. Open Command Prompt and type;
   

   wuauclt.exe /updatenow

3. Open Windows Update from the Control Panel and you should see the update starting to download.
4. If you get a Windows Update error, make sure you cleared the directory out above, and restart your PC.
