# How to add an Administrator account to Windows 10 Operating System on the NovaSeq 6000

The Windows 10 Operating System (OS) on the NovaSeq 6000 will frequently have only a single sbsuser account, and this account will be a part of the Administrators group. Use the following steps to create a new Administrator user account so sbsuser can be safely removed from the Administrators group.

1. Make sure the instrument is idle and no sequencing runs are in progress.
2. Close the NovaSeq 6000 Control Software by selecting the dropdown menu in the top left corner and selecting **Exit Application**.
3. In the Windows Search bar in the bottom left corner, input **lusrmgr.msc** and then open the **Local Users and Groups** console.
4. Select **Action**, and then select **New User.**
5. Input **sbsadmin** under User Name and input the desired password, then confirm the password entry.

* Passwords should be at least 8 characters long
* Have at least one upper case and one lower case letter

6. Select **Create** to add the new user.
7. In the **Local Users and Groups** console, double-click on the new **sbsadmin** account to open the **Properties** menu.
8. Select the **Member Of** tab, then select **Add…** to open the Select Groups window.
9. In the text box below **Enter object names to select**, input **Administrators** and select **Check Names**.
10. Select **OK** and confirm that **Administrators** is now listed under **Member of** text box.
11. Select **Apply** and then **OK**.
12. Exit the **Local Users and Groups** console.
