Solution to the problem that the widows home version does not have Hyper-v

 First of all, this is a problem I encountered when installing docker. I will record it below.

Copy the following code into a text file, then change the suffix to cmd and run it

pushd "%~dp0"
dir /b %SystemRoot%\servicing\Packages\*Hyper-V*.mum >hyper-v.txt
for /f %%i in ('findstr /i . hyper-v.txt 2^>nul') do dism /online /norestart /add-package:"%SystemRoot%\servicing\Packages\%%i"
del hyper-v.txt
Dism /online /enable-feature /featurename:Microsoft-Hyper-V-All /LimitAccess /ALL

Go to the last step after running

Enter y and then restart the computer.
