RunasX - runs an application under specific domain\user, user can pass the details (domain, username, password) via commandline. Solves the problem on Windows Home Editions where user cant store the credentials to credential manager, using runas /savecred.

Windows 7 home premium does not have the feature join a domain network, via system properties or by shift + right click an icon 'run as different user'. While you can't join a domain there are ways you can connect to a domain for running applications if you have a domain account. You can use the runas /netonly command:

//src https://superuser.com/a/917346

runas /netonly /user:mydomain\username "pathToFile/file.exe"
ex. runas /netonly /user:dataxstream\username "C:\Program Files (x86)\Microsoft SQL Server\...\Ssms.exe"

extended solution to accept LM, NTLM, and NTLMv2 session security

//src - https://superuser.com/a/1096731

Access HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
Create a new DWORD (32bit) entry called LmCompatibilityLevel
Modify the entry and set the value to 1

Reboot required.

Windows - Credential Manager

Windows 7: Elevated Program Shortcut

//src - https://superuser.com/a/368776 -- is not available on Windows 7 Home
//you will prompted for the password, then will be saved to Cpanel > Credenrials Manager

runas /savecred /user:domain\user "C:\Windows\notepad.exe"

finally the solution for Windows 7 Home Edition is CreateProcessWithLogonW API :
