The requested PHP extension soap is missing from your system Windows 10

To fix this issue simply go to "xampp/php/" Directory. and open php.ini file with text editor

:extension=soap
;extension=sockets
;extension=sodium
;extension=sqlite3
;extension=tidy
;extension=xmlrpc
;extension=xsl

change it to 

extension=soap
;extension=sockets
;extension=sodium
;extension=sqlite3
;extension=tidy
;extension=xmlrpc
;extension=xsl

Remove the semi-colon from the front of soap extension. All done restart xampp and all should be working.
