WikiHow didn’t say much about adjusting the VM’s settings. I made sure to indicate where I wanted this VM to be created. TechRepublic said that even the small difference would be substantially reduced if the VM was on an SSD.) I found, in practice, that the default 10GB disk size was too small for some applications 20GB was better. ( Contra How-To Geek, it appeared that the performance drawbacks of a dynamic disk would not be noticeable on modern hardware. In the ensuing steps, I went with the default VDI file type, and dynamically allocated storage. WikiHow told me to choose the “Create a virtual hard disk now” option (i.e., not “Use an existing virtual hard disk file”). I decided the better approach was to start with 500MB to 1GB and then expand later, which VirtualBox would freely allow. Initially, I thought 2GB RAM would be good, but for some VMs (especially running on a Windows 7 system) this caused problems. For this, I used VirtualBox > Machine > New. The first step, according to WikiHow, was to create the VM. (Note that it was apparently possible to change the product key after installation, in case the CD or ISO did not match the user’s actual product key.) I used an updated, slipstreamed XP CD with service pack 3 (SP3) installed, as advised in Cameyo’s materials (see other post). ImgBurn was convenient for creating that ISO: insert the CD into the computer and choose the “Create image file from disc” option. WikiHow advised starting with a 32-bit WinXP ISO, extracted if necessary from a Windows XP installation CD. I began with a search for sources of advice. It appeared that virtualizers like Cameyo might not register that a file was added, or needed, for a certain program, if that file was already present and thus was not a new addition that would be detected in the virtualizer’s before-and-after comparison of the system state. Moreover, uninstalling did not always remove all files associated with a program. It might not be feasible to detect and uninstall all processes that had previously been set in motion. Note: it seemed that, to get a clean machine, it might not be good enough to take an existing Windows XP installation or VM and uninstall programs from it. A later post provides an overview of the steps discussed here. This post presents the steps I took to that end. As described in another post, I needed to set up a basic Windows XP virtual machine (VM) in Oracle VirtualBox, so as to have a place to use Cameyo.
