I have to endure until BlueStacks 5 supports Hyper-V.

Requirement

• AutoHotKey
• NirCmd

Configuration

Fill strings to replace __~~__ in Variables.
You can put a short cut command in the BLUSTACKS4_COMMAND refer to the BlueStacks Support page.
If a command exists, the program will be opened when it is executed.
AHK supports .exe converter, so if you're interested, look for them.
