Answer: nothing
Step-by-step explanation:
The operating system (OS) of the destination computer should not affect the encryption of the file. Whether you move the encrypted file to a Windows 8 or Windows 7 Home Premium computer, the file will remain encrypted and require the correct decryption key to be accessed. However, if the destination computer does not have the necessary software or tools to handle the encryption, you may not be able to access the file even with the correct decryption key. In that case, you would need to install the necessary software or tools on the destination computer in order to access the encrypted file.
