If your would like to use Hyper-v but you are running Windows Home, you know it is not available. To activate it you can try this batch script.
Notice: This file is not mine. I found it on the Iternet, analyzed it (to make sure it was safe) and ran the commands one by one by hand. After that i restartet the computer and the hyper-v-manager was available.
Before I posted it here I added the code comments for clarity.
@echo off
REM search %SystemRoot%\servicing\Packages\
REM for *.mum files having *Hyper-V* somewhere in the name
REM *.mum files are update files from Windows updater
REM write the names of the found files to a file called "hyper-v.txt"
dir /b %SystemRoot%\servicing\Packages\*Hyper-V*.mum >hyper-v.txt
REM install all update files found in the file "hyper-v.txt"
for /f %%i in ('findstr /i . hyper-v.txt 2^>nul') do dism /online /norestart /add-package:"%SystemRoot%\servicing\Packages\%%i"
REM delete the "hyper-v.txt" file
del hyper-v.txt
REM enable Hyper-V
Dism /online /enable-feature /featurename:Microsoft-Hyper-V -All /LimitAccess /ALL
REM wait for input
pause
