+Subject: fix: revert "Collect GPU memory on GPU process start on Windows"
+
+This patch reverts a CL that we believe is causing Electron crashes within GetWmiPerferredMonitorSourceMode. Reviewing the CL history, it seems as though this change has been reverted and relanded several times, and is suspected of causing a crash. This patch can be removed when the cause of the crash is either fixed upstream or pinpointed within Electron itself.
+
+This reverts commit a10ac33565e0e7ada7f828d52be8837a67b304f3.
