A field technician is servicing a graphic designer's workstation that is currently executing a 32-bit edition of Windows 10 Professional. The workstation hardware was recently upgraded to 16 GB of RAM, but the operating system can only address approximately 3.7 GB. The designer asks the technician to upgrade the machine to 64-bit Windows 10 Professional while retaining all currently installed applications and user settings. Which of the following installation methods must the technician explain is required to complete this change?
- Perform a clean installation of the 64-bit operating system after backing up user data, as direct in-place upgrades between 32-bit and 64-bit architectures are unsupported.Cevap
- BExecute an in-place upgrade directly from the 64-bit installation media media setup wizard while running the existing 32-bit operating system.
- CRun the deployment command dism.exe /online /set-architecture:x64 from an elevated command prompt to switch the kernel binaries in place.
- DUpdate the Windows product key to Windows 10 Pro for Workstations within Settings to automatically unlock 64-bit memory addressing capabilities.
Cevap
A clean installation of the 64-bit operating system must be performed after backing up user data, because cross-architecture in-place upgrades are not supported by Windows.
Moving from a 32-bit OS to a 64-bit OS requires a complete change of system binaries, core kernel structures, and device driver models. Microsoft Windows does not support cross-architecture in-place upgrades. Therefore, a technician must back up user data and perform a clean installation from 64-bit installation media.
