For example, instead of `%LocalAppData%`, use `~\AppData\Local`.

+#### Cache segment restore timeout
+A cache gets downloaded in multiple segments of fixed sizes (`1GB` for a `32-bit` runner and `2GB` for a `64-bit` runner). Sometimes, a segment download gets stuck which causes the workflow job to be stuck forever and fail. Version `v3.0.8` of `actions/cache` introduces a segment download timeout. The segment download timeout will allow the segment download to get aborted and hence allow the job to proceed with a cache miss.
+
+Default value of this timeout is 60 minutes and can be customized by specifying an [environment variable](https://docs.github.com/en/actions/learn-github-actions/environment-variables) named `SEGMENT_DOWNLOAD_TIMEOUT_MINS` with timeout value in minutes.
+
+#### Update a cache
+A cache today is immutable and cannot be updated. But some use cases require the cache to be saved even though there was a "hit" during restore. To do so, use a `key` which is unique for every run and use `restore-keys` to restore the nearest cache. For example:
+  ```yaml
+      - name: update cache on every commit
+        uses: actions/cache@v3
+        with:
+          path: prime-numbers
+          key: primes-${{ runner.os }}-${{ github.run_id }} # Can use time based key as well
+          restore-keys: |
+            primes-${{ runner.os }}
+  ```          
+  Please note that this will create a new cache on every run and hence will consume the cache [quota](#cache-limits).
+  
+#### Use cache across feature branches
+Reusing cache across feature branches is not allowed today to provide cache [isolation](https://docs.github.com/en/actions/using-workflows/caching-dependencies-to-speed-up-workflows#restrictions-for-accessing-a-cache). However if both feature branches are from the default branch, a good way to achieve this is to ensure that the default branch has a cache. This cache will then be consumable by both feature branches.
+
+#### Improving cache restore performance on Windows/Using cross-os caching
+Currently, cache restore is slow on Windows due to tar being inherently slow and the compression algorithm `gzip` in use. `zstd` is the default algorithm in use on linux and macos. It was disabled on Windows due to issues with bsd tar(libarchive), the tar implementation in use on Windows. 
+
+To improve cache restore performance, we can re-enable `zstd` as the compression algorithm using the following workaround. Add the following step to your workflow before the cache step:
+
+```yaml
+    - if: ${{ runner.os == 'Windows' }}
+      name: Use GNU tar
+      shell: cmd
+      run: |
+        echo "Adding GNU tar to PATH"
+        echo C:\Program Files\Git\usr\bin>>"%GITHUB_PATH%"
+```
+
+The `cache` action will use GNU tar instead of bsd tar on Windows. This should work on all Github Hosted runners as it is. For self-hosted runners, please ensure you have GNU tar and `zstd` installed.

So the above workaround will ensure `zstd` is used for caching on all platforms thus resulting in the same cache version for the same cache key.
