Any technician with access to the certificate file can read the thumbprint by viewing the certificate with CertMgr. Instructions for viewing the thumbprint with CertMgr are in the [Create or modify the SEMM Configuration Manager scripts](#create-or-modify-the-semm-configuration-manager-scripts) section of this article. Removal of SEMM from a device deployed with Configuration Manager using these scripts is as easy as uninstalling the application with Configuration Manager. This action starts the ResetSEMM.ps1 script and properly unenrolls the device with the same certificate file that was used during the deployment of SEMM. + +>[!NOTE] +>Microsoft Surface recommends that you create reset packages only when you need to unenroll a device. These reset packages are typically valid for only one device, identified by its serial number. You can, however, create a universal reset package that would work for any device enrolled in SEMM with this certificate. + +>We strongly recommend that you protect your universal reset package as carefully as the certificate you used to enroll devices in SEMM. Please remember that – just like the certificate itself – this universal reset package can be used to unenroll any of your organization’s Surface devices from SEMM. + +>When you install a reset package, the Lowest Supported Value (LSV) is reset to a value of 1.

Because this action is a new enrollment and not a change in configuration on a device already enrolled in SEMM, the device will prompt for the certificate thumbprint before ownership is taken. \ No newline at end of file
