C:\Windows\WinSxS\amd64... - Observe Run dialog hangs after the
WinSxS\(and consumes ~1GiB of memory)
✔️ Expected Behavior
Consistent typing experience regardless of underlying file system hierarchy (within reason).
The combo box (and underlying search) should probably have the results capped at a smaller amount.

Research direction
Reproduce the hang in PowerToys Run by entering C:\Windows\WinSxS\amd64, then trace the directory enumeration and result-population path. Confirm how many entries are loaded and identify a suitable result cap; done means typing remains responsive and memory use does not grow excessively on large directories.
