How to start Device Registration Service

On the Windows Start menu, click All Programs > Kofax > Device Registration Service > Device Configuration Manager.
This opens the Device Registration System Configuration dialog box.
Click Yes if you are prompted to confirm that you want to make changes to the computer.
On the Service tab, in Run Service under choose a designated local or domain account to run DRS service instead of running the service under Local System Account (due to the Windows update's removal of the SQL server database instance). Click Log on as a service permission to the account:
1. Open Local Security Policy, click Start > Control Panel > Administrative Tools > Local Security Policy (double-click).
2. In the console tree, double-click Local Policies and then click User Rights Assignment.
3. In the details pane, double-click Log on as a service.
4. Click Add User or Group..., and then add the appropriate account to the list of accounts that possess the Log on as a service right.
5. Grant write access to the following folder for the new account: C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files
  Run this command to grant permission to the account which will be configured in the DRS Configuration Tool: C:\Windows\Microsoft.NET\Framework64\version \Aspnet_regiis.exe -ga user Where version is the full version number for .NET and user is the user name that your application runs under.
6. Register DRS services with the operating system. Some DRS are registered with the operating system.
  Run the following command: netsh http add urlacl url=http(s)://+:{port number}/ user={user account name}
7. (Optional) Configure certificate on DRS ports. If TLS is configured in the DRS Configuration Tool, configure the SSL certificate on DRS ports:
  Run the following command: netsh http add sslcert ipport=0.0.0.0:{port number} certhash={hash value of your certificate} appid={GUI}
  Where certhash can be taken from the thumbprint of your certificate from Windows Certificates and appid is any valid GUID.
Allow Full control permission of the two LocalDB database files to the account and restart the service.
