laa_toggle

Rust console app to analyze/modify the LAA flag in Windows PE-binaries.
With LAA enabled, 32bit apps can allocate up to 4GiB of memory, instead of only 2GiB (on modern 64bit systems).

Requires 1 argument: the path to the EXE file.
The simplest way is to just drag the app you want to analyze/modify onto this one.

Depending on your Windows / Windows Defender version, you might have to flip the "Security: Unblock" checkbox in File Properties.
This is due to laa_toggle modifying an executable, which might flag it as malware.
