@Saksham - Welcome to Microsoft Q&A and thanks for reaching out.
- We do not have an az uninstall --version command. You uninstall the Azure CLI from the Windows "Apps and Features" list.
- To install the Azure CLI on Windows, you must use PowerShell, or an MSI installer, which gives you access to the CLI through the Windows Command Prompt (CMD).
- To Install the CLI for windows, please go through this document: install-azure-cli-windows
- You will need to uninstall, then reinstall the specific version.
Hope this helps. and please feel free to reach out if you have any further questions.
