Fixes [docker/for-win#6284](https://github.com/docker/for-win/issues/6284). - Added a check that virtualization is enabled in the BIOS. **Filesharing** - Fixed a bug where renaming parent directories of shared folders led to spurious `File not found` errors. Fixes [docker/for-win#6200](https://github.com/docker/for-win/issues/6200). - Fixed bug where a letter and two digit root folder name causes docker-compose to fail creating directories inside the volume. Fixes [docker/for-win#6248](https://github.com/docker/for-win/issues/6248). - Fixed a bug which prevented containers from seeing file updates on shared volumes, when under load and a container restarts. Fixes [docker/for-win#5530](https://github.com/docker/for-win/issues/5530#issuecomment-608804192). - Fixed a bug where host paths are incorrectly translated into VM paths. Fixes [docker/for-win#6209](https://github.com/docker/for-win/issues/6209). - Fixed bug receiving file events on long paths (> 260 characters). Fixes [docker/for-win#6337](https://github.com/docker/for-win/issues/6337). - Docker Desktop represents valid directory junctions as directories (rather than symlinks) and handles cache invalidation and event injection properly. Fixes [docker/for-win#5582](https://github.com/docker/for-win/issues/5582). **Other fixes** - Reduced the size of the Docker Desktop installer from 960 MB to 409 MB. - Added an option to delete data from the Troubleshoot screen. - Fixed a bug where containers disappeared from the UI when Kubernetes context is invalid. Fixed [docker/for-win#6037](https://github.com/docker/for-win/issues/6037). - Fixed Windows event logs filtering when copying them to the Docker Desktop log files. Fixed [docker/for-win#6258](https://github.com/docker/for-win/issues/6258). - Fixed a handle leak in `vpnkit-bridge`. Fixed [docker/for-win#5841](https://github.com/docker/for-win/issues/5841) - Fixed bug when removing Docker Desktop virtual switch. - Added a link to the Edge channel from the UI. - Made the embedded terminal resizable. - Fixed a bug which only respected the `expose on TCP` Docker engine API setting on application restart. Setting will now take effect when the Apply button is clicked. - Fixed a bug where diagnostic upload would fail if the username contained spaces. - Docker Desktop now reads the Hyper-V VM disk max size on startup and uses it as the value to display in the Settings. - Fixed a bug where the Docker Desktop UI could be started without the engine. Fixes [docker/for-win#5376](https://github.com/docker/for-win/issues/5376).

This section details bug fixes and minor changes in Docker Desktop, focusing on WSL 2 and file sharing. WSL 2 improvements include exposing host ports, refreshing distributions, defaulting to WSL 2 on install, detecting missing kernels, and supporting `chmod/chown` on bind mounts. File sharing fixes address issues with renaming directories, creating directories inside volumes, file updates on shared volumes, incorrect path translations, long paths, and directory junctions. Other fixes include reducing the installer size, adding a data deletion option, fixing container UI issues, improving event log filtering, fixing a handle leak, and enhancing the embedded terminal.
