# Emulator shows a black screen on launch after a Windows update — how to fix it

A black screen that appears right after a Windows update is almost always the GPU driver being swapped out, or a Windows security feature (Memory Integrity / Hyper-V) being re-enabled — not a broken emulator. Fix it in order: roll back or cleanly reinstall the GPU driver, then re-disable the virtualization / Core-Isolation feature the update turned back on. The emulator itself does not need reinstalling.

Your emulator was working perfectly. Then Windows installed an update, rebooted, and now the emulator opens to a black screen, a blank white window, or a window that never renders the game — sometimes with audio playing behind it, sometimes frozen, sometimes crashing back to desktop after a few seconds. Nothing about the emulator itself changed: you didn't reinstall it, didn't touch a setting, didn't switch game versions. The only thing that changed is Windows.

Cause: A Windows cumulative or feature update can silently change three things an emulator depends on, and any one of them produces a black screen:

  The GPU driver was replaced or reset. Updates frequently swap your working graphics driver for a newer (or a generic Microsoft Basic Display) one. Emulators lean hard on the GPU to render, so a driver that's mismatched, half-installed, or reverted shows nothing but black.
  A Windows security feature was re-enabled. Memory Integrity (Core Isolation), Hyper-V, and the Virtual Machine Platform can be switched back on by an update. Those grab the CPU's virtualization layer — which Android emulators (GameLoop, BlueStacks, LDPlayer, MEmu) need to boot — so the engine starts but never paints a frame.
  The display/fullscreen path changed. A driver reset can change your default GPU (laptops flip back to the integrated chip), refresh rate, or resolution, leaving the emulator trying to render fullscreen into a mode that no longer exists = black.


Because the trigger was an update, the fix is to undo or rule out what the update changed — in order, most-likely first. Reinstalling the emulator almost never helps, since the emulator isn't what broke.
