# How to install osquery and enroll Windows devices into Fleet
The easiest way to install osquery and enroll Windows devices into your Fleet instance is to use the Fleet osquery installer.
Alternatively, you can run a preview environment of Fleet locally (which automatically adds your device to the locally running Fleet server). Check out the [Getting Started](https://fleetdm.com/get-started) guide for instructions on setting that up.
## Prerequisites
Before installing osquery on Windows and enrolling that Windows device, you will need access to a Fleet server (see [Deploying Fleet on Render](https://fleetdm.com/guides/deploying-fleet-on-render) for an example.)
If you don’t already have it, you will also need to install the `fleetctl` CLI tool. `fleetctl` can be installed via `npm` by running the following command:
```
npm i -g fleetctl
```
After the above command has run successfully, you can confirm that you now have the `fleetctl` CLI tool by running:
```
fleetctl --version
```
The above command should return an output similar to the example below:
> You can generate an osquery installer using `fleetctl` for Windows on macOS and even Linux distributions, but for this article we are assuming generating on a Windows device. To generate an osquery installer for a different OS, check out the guides for [macOS](https://fleetdm.com//guides/how-to-install-osquery-and-enroll-macos-devices-into-fleet) and [Linux](https://fleetdm.com//guides/how-to-install-osquery-and-enroll-linux-devices-into-fleet).
## Installing osquery
Head over to the Hosts page on Fleet and click on the “Generate installer” button, which will present a pop-up that allows you to choose the type of installer you want to generate. Make sure you are on the “Windows” tab and click on the clipboard icon.
Next, head over to your Windows command prompt (making sure that you are running with administrator privilege and Docker is running), paste the copied command, and then hit enter.
Once `fleetctl` has finished creating your osquery installer, it will produce an installer file called `fleet-osquery.msi` in your current directory and display instructions on how to proceed.
## Running the installer
Double-click the installer and follow the guided steps to successfully install osquery on your Windows device and enroll it into Fleet!
If you’re managing an enterprise environment, you will likely have a deployment tool like [Munki](https://www.munki.org/munki/), [Jamf Pro](https://www.jamf.com/products/jamf-pro/), [Chef](https://www.chef.io/), [Ansible](https://www.ansible.com/), or [Puppet](https://puppet.com/) to deliver software to your devices. You can distribute your osquery installer and add all your devices to Fleet using your software management tool of choice.
