How do I determine if an unbootable copy of Windows is a 64-bit or 32-bit installation?



As an IT admin, it can be useful to know the type of Windows installation (64-bit or 32-bit) on a machine that is unbootable. This article will discuss how to determine which type of installation is present in such a situation.

First, it is important to note that the 64-bit and 32-bit Windows installations are completely different, and should not be confused with the hardware architecture of the machine (which may be 64-bit or 32-bit). This means that a 64-bit version of Windows can be installed on a 32-bit hardware architecture, and vice versa.

If the unbootable machine has a 32-bit hardware architecture, then it is likely that the installation of Windows is a 32-bit version. On the other hand, if the machine has a 64-bit hardware architecture, then the installation of Windows may be either a 32-bit or 64-bit version.

When the machine is unbootable, the easiest way to determine the type of Windows installation is to use a bootable diagnostic tool or CD. These tools are designed to analyze the installed Windows system on the machine, and will display the type of Windows installation present. If the machine is not able to boot into the diagnostic tool, then a bootable Linux distribution can be used instead. After booting into Linux, the type of Windows installation can be identified by examining the files present in the Windows directory.

If the machine has a hard drive that can be accessed, then the type of Windows installation can also be determined by examining the Windows system files. The Windows directory contains a file named “winver.exe”, which contains information about the installed version of Windows. If this file is present, then it can be opened in a text editor and the type of Windows installation can be determined from the version string that is present in the file.

Finally, if the machine has a removable storage medium such as a USB drive or CD, then the installation files for the Windows system can be extracted from the medium and examined to determine the type of Windows installation. The installation files typically contain a “setup.exe” file, which can be opened in a text editor and examined for the version string.

In conclusion, determining the type of Windows installation on an unbootable machine can be done by using a bootable diagnostic tool or CD, examining the Windows system files, or extracting the installation files from a removable storage medium.
