PatchPE

PatchPE is a dual-purpose tool designed for software enthusiasts and developers. Its primary function is to patch Portable Executable (PE) headers to bypass strict OS version checks, granting older systems like Windows NT and XP access to modern software. Its second, equally important feature is enabling the Large Address Aware (LAA) flag. This allows 32-bit applications to break the 2 GB memory barrier, a vital upgrade for data-heavy programs, games, and professional tools, ensuring they can leverage available system resources for optimal performance.
