220-1102 Operating Systems Practice Question
A technician has been asked to determine whether a Windows 10 computer is running a 32-bit or 64-bit version of the operating system. The technician is logged in as a standard user without administrative privileges. Which built-in tool can the technician use to find this information?
⚠ Common exam trap
Candidates often assume msconfig (System Configuration) is the go-to tool for system information because of its name, but it lacks the specific OS architecture detail, while msinfo32 is the correct utility for this purpose.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
System Information (msinfo32)
System Information (msinfo32) displays detailed system configuration, including the OS architecture (32-bit or 64-bit) under 'System Summary' > 'System Type'. It is accessible to standard users without administrative privileges, making it the correct built-in tool for this task.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
System Configuration (msconfig)
Why it's wrong here
msconfig is designed for boot configuration, startup programs, and service management, not for inspecting OS architecture. Although the General tab lists the installed Windows version, it does not explicitly display whether the OS is 32-bit or 64-bit; determining that from the version string requires inference. Additionally, changing settings in msconfig often demands administrative privileges, making it a poor choice for a quick, read-only check.
- ✓
System Information (msinfo32)
Why this is correct
System Information (msinfo32) is the definitive graphical tool for this task because its System Summary explicitly shows an 'OS Architecture' entry (e.g., '64-bit' or '32-bit') and a 'System Type' value such as 'x64-based PC'. It provides a comprehensive overview of hardware and software without requiring administrative rights, and it is accessible to standard users. This makes it the most direct and reliable method for determining a Windows 10 installation's bitness.
- ✗
Device Manager
Why it's wrong here
Device Manager focuses exclusively on hardware devices, their drivers, and resource assignments; it has no field that reports the operating system's architecture. While some driver details may imply a driver's bitness, the utility never surfaces the OS-level bitness. Therefore, using Device Manager to answer this question is irrelevant and would require cross-referencing other tools or system properties.
- ✗
Registry Editor (regedit)
Why it's wrong here
The Registry Editor (regedit) can reveal bitness indirectly via keys like HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion, but this is not a standard or user-friendly approach. The relevant values, such as ProcessorArchitecture, are not strictly standardized for general users, and navigating the registry to find them is error-prone. Additionally, while standard users can read many keys, some branches are restricted, and the tool lacks the clarity of a dedicated system information utility.
