# How to update Windows 10 account credentials on Benchtop Instruments
Benchtop Instruments running the Windows 10 Operating System (OS), may require periodic password updates. When prompted, as shown in **Figure 1a**, select OK, then update the Windows password, as shown in **Figure 1b**.
**Figure 1a.** Password update prompt.
**Figure 1b.** Password update.
**Actions Post Password Update:**
Universal Copy Service (UCS) and Local Run Manager (LRM) are components of the Control Software which are used to transfer sequencing run data, setup runs, and analyze data. These components run as Windows services which may be configured to **Log On As** any Windows account. Changing the password of a Windows account running UCS or LRM services does not automatically update the passwords for the services. See below for instructions to update the UCS and LRM service passwords following a Windows account password update.
If the password for a Windows account which is running the UCS and LRM services is updated in Windows, but not in the LRM and UCS services, the instrument may fail to operate. Disabled operation prevents new run settings from being entered and data transfer from completing. Control software may fail to initialize, or the following errors may occur.
**Error message:**
* "Cannot initiate communication with Universal Copy Service. Make sure that the service is installed and started."
* "The following required software is either not installed or not running. Sequencing cannot be performed until this problem is fixed. Contact Illumina Technical Support. Universal Copy Service."
**To update UCS and LRM service credentials with Local Run Manager v3.x or below, see the following instructions:**
1. Select the Windows icon in the lower left corner of the screen. In the Windows search field, enter **Services**. When **Services** appears in the results, right-click and select **Run as administrator**.
1. 
2. If prompted, enter administrator credentials (by default the credentials will be the **sbsadmin** user credentials) in the pop-up window.
3. Locate the Illumina services.
4. Right-click on **Illumina** **Local Run Manager Analysis Service**. Select **Stop**.
1. 
5. Right-click again on **Illumina Local Run Manager Analysis Service**.
6. Select **Properties** and navigate to the **Log On** tab.
7. Select **This account** and **Browse**... to search for the account. In the **Select User** window, select **Advanced** and then **Find Now**. Select the Windows account for which the password was just updated (default **sbsuser**) from the search results.
1. 
8. Select **OK** to acknowledge both windows.
9. Enter the new account (default **sbsuser**) password, select **Apply** and **OK**.
10. Restart the service.
11. Repeat steps 4-10 for **Illumina Local Run Manager Job Service**, **Illumina Universal Copy Service**,and **Illumina Run Copy Service** if they are present in the list.
12. Shut down and restart the system.
**To update UCS and LRM service credentials with Local Run Manager v4.x, see the following instructions:**
1. In Local Run Manager (LRM), configure the Illumina services to use respective **Log On As** accounts via the admin account by accessing the **Tools** menu.
1. 
2. Open **System Settings**, select **Service Accounts** and select the respective option for each **Service** (note that Illumina recommends Universal Copy Service is **ALWAYS** configured with the sbsuser account.
1\.
```
```
**Note:** If runs are saved **locally**, the Analysis Service and Job service should be set to Local System account and Universal Copy Service can be set to Local Service Account.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://knowledge.illumina.com/instrumentation/general/instrumentation-general-reference_material-list/000001932.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
