If you upgrade from 32-bit Windows 7 or 8 (8.1) to Windows 10, the process installs the 32-bit version of the system. Also, some devices have a 32-bit preinstalled system, but the processor supports 64-bit Windows 10 and it is possible to change the OS to it (and sometimes it can be useful, especially if you have increased the amount of RAM on your computer or laptop).
This tutorial shows how to change a 32-bit Windows 10 to a 64-bit one.
Installing Windows 10 x64 instead of a 32-bit system
When you upgrade to Windows 10 (or purchase a Windows 10 32-bit device), you are granted a license that also applies to a 64-bit system (in both cases, it is registered on the Microsoft website for your equipment and the key you do not need to know).
Unfortunately, without reinstalling the system to change 32-bit to 64-bit will not work: the only way to change the bitness of Windows 10 is to perform a clean installation of the x64 version of the system in the same edition on a computer, laptop or tablet (you can not remove the already existing data on the device, but the drivers and programs will have to reinstall).
Note: if there are multiple partitions on the disk (that is, there is a conditional d disk), it is a good solution to migrate your user data (including from the desktop and system document folders) to it.
The procedure will be as follows:
- Go to Settings-System-about (about the system) and pay attention to the “system Type”parameter. If it indicates that you have a 32-bit operating system, an x64-based processor, this means that your processor supports 64-bit systems (if the x86 processor does not support and no further steps should be taken). Also note the release (revision) of your system in the “Windows Specifications”section.
- Important step: if you have a laptop or tablet, make sure that the manufacturer’s official website has drivers for 64-bit Windows for your device (unless bit depth is specified, both system options are generally supported). It is advisable to download them.
- Download the original Windows 10 x64 ISO image from the Microsoft web site (currently all editions of the system are contained in the same image) and create a bootable USB flash drive (disk) or make a bootable Windows 10 x64 USB flash drive official (using Media Creation Tool).
- Start the system installation from the flash drive. At the same time, if you receive a request about which version of the system to install — select the one that was displayed in the system information (in step 1). You do not need to enter the product key during installation.
- If the” C drive “had important data, then in order not to delete it, do not format the C drive during installation, just select this partition in the” full installation “mode and click” Next ” (the files of the previous Windows 10 32-bit will be placed in the Windows folder.old, which in the future can be removed).
- Complete the installation process and then install the original system drivers.
The process of transition from 32-bit Windows 10 64-bit will be completed. The main task — to correctly go through the installation system from a USB drive and then installing the drivers to get the OS in the correct bitness.
