The 2 GB limit refers to a physical memory barrier for a process running on a 32-bit operating system, which can only use a maximum of 2 GB of memory. [1] The problem mainly affects 32-bit versions of operating systems like Microsoft Windows and Linux, although some variants of the latter can overcome this barrier. [2]
Can use Physical Address Extension to create a virtual disk in memory normally inaccessible to 32-bit versions of Microsoft Windows (both memory above the 4 GB point, and memory in the PCI hole). [13] There is also an open source plugin that replaces the RAM drive on Bart's PE Builder with one based on Gavotte's rramdisk.sys. [14]
In January 2023, version 109 of the Chromium-based Microsoft Edge became the last version of Edge to support Windows 7, Windows 8/8.1, Windows Server 2012, and Windows Server 2012 R2. [121] Alongside this, several other web browsers based on the Chromium codebase also dropped support for these operating systems after version 109, including ...

Many 16-bit Windows legacy programs can run without changes on newer 32-bit editions of Windows. The reason designers made this possible was to allow software developers time to remedy their software during the industry transition from Windows 3.1x to Windows 95 and later, without restricting the ability for the operating system to be upgraded to a current version before all programs used by a ...
However, "client" versions of 32-bit Windows (Windows XP SP2 and later, Windows Vista, Windows 7) limit physical address space to the first 4 GB for driver compatibility [16] even though these versions do run in PAE mode if NX support is enabled. Windows 8 and later releases will only run on processors which support PAE, in addition to NX and SSE2.
A 32-bit application can be given a full 4 gigabytes of virtual memory on a 64-bit system, whereas on a 32-bit system, some of this addressable memory is lost because it is used by the kernel and memory-mapped peripherals such as the display adaptor, typically resulting in apps being able to use either 2GB or 3GB of RAM at most.
