Microsoft to stop security updates for Windows 10 on 32-bit systems
If you own a 32-bit Windows 10 PC/laptop, now is the time to replace it. Starting with the Windows 10 May 2020 Mega update, Microsoft will no longer be releasing security patches and other updates for 32-bit builds. Microsoft had decided to concentrate on 64-bit Windows 10 builds for future security patches and updates.
The Microsoft blog states that starting with Windows 10 2004, new OEM computers will be required to use 64-bit builds of the operating system.
Beginning with Windows 10, version 2004, all new Windows 10 systems will be required to use 64-bit builds and Microsoft will no longer release 32-bit builds for OEM distribution. This does not impact 32-bit customer systems that are manufactured with earlier versions of Windows 10; Microsoft remains committed to providing feature and security updates on these devices, including continued 32-bit media availability in non-OEM channels to support various upgrade installation scenarios.
Very few users use Windows 10 32 bit PCs and laptops according to the Steam Hardware & Software April 2020 survey. The survey shows that only 0.20% use Windows 10 32-bit while majority i.e. 86.08% of PC/laptop users now use Windows 10 64-bit.
The difference between 64 bit and 32-bit processor
A 64-bit processor is more capable than a 32-bit processor because it can handle more data at once. A 64-bit processor is capable of storing more computational values, including memory addresses, which means it’s able to access over four billion times the physical memory of a 32-bit processor. That’s just as big as it sounds.
32-bit processors are perfectly capable of handling a limited amount of RAM (in Windows, 4GB or less), and 64-bit processors are capable of utilizing much more. This Microsoft page details the memory limitations for multiple versions of Windows.
