+# Update HoloLens
+
+HoloLens uses Windows Update, just like other Windows 10 devices. Your HoloLens will automatically download and install system updates whenever it is plugged-in to power and connected to the Internet, even when it is in standby.
+
+This article will walk through HoloLens tools for:
+
+- viewing your current operating system version (build number)
+- checking for updates
+- manually updating HoloLens
+- rolling back to an older update
+
+## Check your operating system version (build number)
+
+You can verify the system version number, (build number) by opening the Settings app and selecting **System** > **About**.
+
+## Check for updates and manually update
+
+You can check for updates any time in settings.  To see available updates and check for new updates:
+
+1. Open the **Settings** app.
+1. Navigate to **Update & Security** > **Windows Update**.
+1. Select **Check for updates**.
+
+If an update is available, it will start downloading the new version. After the download is complete, select the **Restart Now** button to trigger the installation. If your device is below 40% and not plugged in, restarting will not start installing the update.
+
+While your HoloLens is installing the update, it will display spinning gears and a progress indicator. Do not turn off your HoloLens during this time. It will restart automatically once it has completed the installation.
+
+HoloLens applies one update at a time.  If your HoloLens is more than one version behind the latest you may need to run through the update process multiple times to get it fully up to date.
+
+## Go back to a previous version - HoloLens 2
+
+In some cases, you might want to go back to a previous version of the HoloLens software. You can do this by using the Advanced Recovery Companion to reset your HoloLens to the earlier version.
+
+> [!NOTE]
+> Going back to an earlier version deletes your personal files and settings.
+
+To go back to a previous version of HoloLens 2, follow these steps:
+
+1. Make sure that you don't have any phones or Windows devices plugged in to your PC.
+1. On your PC, download the [Advanced Recovery Companion](https://www.microsoft.com/p/advanced-recovery-companion/9p74z35sfrs8?activetab=pivot:overviewtab) from the Microsoft Store.
+1. Download the [most recent HoloLens 2 release](https://aka.ms/hololens2download).
+1. When you have finished these downloads, open **File explorer** > **Downloads**. Right-click the zipped folder that you just downloaded, and select **Extract all** > **Extract** to unzip it.
+1. Connect your HoloLens to your PC using a USB-A to USB-C cable. (Even if you've been using other cables to connect your HoloLens, this one works best.)
+1. The Advanced Recovery Companion automatically detects your HoloLens. Select the **Microsoft HoloLens** tile.
+1. On the next screen, select **Manual package selection** and then select the installation file contained in the folder that you unzipped in step 4. (Look for a file with the .ffu extension.)
+1. Select **Install software**, and follow the instructions.
+
+## Go back to a previous version - HoloLens (1st Gen)
+
+In some cases, you might want to go back to a previous version of the HoloLens software. You can do this by using the Windows Device Recovery Tool to reset your HoloLens to the earlier version.
+
+> [!NOTE]
+> Going back to an earlier version deletes your personal files and settings.
+
+To go back to a previous version of HoloLens 1, follow these steps:
+
+1. Make sure that you don't have any phones or Windows devices plugged in to your PC.
+1. On your PC, download the [Windows Device Recovery Tool (WDRT)](https://support.microsoft.com/help/12379).
+1. Download the [HoloLens Anniversary Update recovery package](https://aka.ms/hololensrecovery).
+1. When the downloads finish, open **File explorer** > **Downloads**. Right-click the zipped folder you just downloaded, and select **Extract all** > **Extract** to unzip it.
+1. Connect your HoloLens to your PC using the micro-USB cable that it came with. (Even if you've been using other cables to connect your HoloLens, this one works best.)
+1. The WDRT will automatically detect your HoloLens. Select the **Microsoft HoloLens** tile.
+1. On the next screen, select **Manual package selection** and choose the installation file contained in the folder you unzipped in step 4. (Look for a file with the .ffu extension.)
+1. Select **Install software**, and follow the instructions.
+
+> [!NOTE]
+> If the WDRT doesn't detect your HoloLens, try restarting your PC. If that doesn't work, select **My device was not detected**, select **Microsoft HoloLens**, and then follow the instructions.
