+### Does this problem relate to file caching?
+
+The default behaviour of libvips is to cache input files, which can lead to `EBUSY` or `EPERM` errors on Windows.
+Use [`sharp.cache(false)`](https://sharp.pixelplumbing.com/api-utility#cache) to switch this feature off.

+
+Images that contain EXIF Orientation metadata are not auto-oriented. By default, EXIF metadata is removed.
+
+- To auto-orient pixel values use the parameter-less [`rotate()`](https://sharp.pixelplumbing.com/api-operation#rotate) operation.
+- To retain EXIF Orientation use [`keepExif()`](https://sharp.pixelplumbing.com/api-output#keepexif).

-* `--arch`: one of `x64`, `ia32`, `arm` or `arm64`.
-* `--arm-version`: one of `6`, `7` or `8` (`arm` defaults to `6`, `arm64` defaults to `8`).
-* `--libc`: one of `glibc` or `musl`. This option only works with platform `linux`, defaults to `glibc`
-* `--sharp-install-force`: skip version compatibility and Subresource Integrity checks.

-These values can also be set via environment variables,
-`npm_config_platform`, `npm_config_arch`, `npm_config_arm_version`, `npm_config_libc`
