To test website compatibility under IE6, I decided to set up a Windows XP virtual machine. However, I found that some XP systems do not have IE6 as the default browser. When I finally found one with IE6 by default, it kept prompting that the product key was incorrect. I searched online and tried several keys, but none of them worked. Finally, I found the solution:
When creating a new virtual machine, you should select the option to install the operating system later. Otherwise, even if the operating system is a cracked version, it will still prompt you to enter a product key.
Once the virtual machine is created, you can then install the operating system by following these steps:
This makes the process just like installing the XP operating system on a regular computer. If it is a cracked version, you can use it long-term after the installation is complete.
