[Bug]: Revealing a file in File Explorer takes over 2 seconds on Windows#33063
Area
apps/desktop
Steps to reproduce
On Windows, open a file in the file preview panel and press Open in File Explorer.
Expected behavior
Explorer opens with the file selected about as fast as the OS allows.
Actual behavior
About 2.4 s here. T3 starts a hidden Windows PowerShell before Explorer. T3's own server work takes 8-55 ms (server traces).
Time until the file is selected (Windows 11 26200, Core Ultra 7 255H, 4 runs each, after a warm-up):
| Route | Average |
|---|---|
main (PowerShell then explorer /select) | 2,453 ms |
Electron shell.showItemInFolder | 1,279 ms |
Separately, in the real launcher: main 2,208 ms, skipping PowerShell 1,747 ms.
