# How to switch user accounts on Illumina Windows 10 Sequencing System

Illumina benchtop systems (iSeq 100, MiniSeq, MiSeq RUO and NextSeq 500/550) that are running the Windows 10 operating system are installed with both standard and administrator accounts. To successfully upgrade control software and configure network settings, switch to a Windows administrator account (the default is “sbsadmin”). When the instrument is idle:

1. Select the Start button in the lower left corner of the screen.
2. Select the username icon or picture.
3. Select **switch user** or **log out.**
4. Log into the Windows administrator account.
