Bug description:
# Add a code block here, if required

Starting with 13.0 Python I get the warning "failed to find real location of python.exe" but only if I run it from a ram disk, never when i run it from a network share. I wrote an editor in Python back in 2017 and it was very fast except for startup, which took as long as 700 msec. I knew Microsoft C was fast in part because its DLLs were preloaded into memory. One day I was watching a Dave Plummer video on YouTube and he mentioned ram drives which I hadn't thought about since the days of MS-DOS. I found and installed IMDISK on Windows 10, and later Windows 11. The editor, and everything else, runs instantly and I've never had any problems with Python running from a ram disk. So, I'm writing to see if you guys could either make an exception for ram drives, or provide a way to turn off that warning message. Thanks in advance.

调研方向

未指定源文件或测试。首先使用 IMDISK RAM 磁盘在 Windows 上通过 CPython 3.13 重现该警告,然后定位解析 python.exe 并发出消息的代码。当 RAM 磁盘场景得到适当处理,或者可以在不影响其他启动场景的情况下禁用该警告时,即可视为完成。
