Which of the following is the FIRST option to check in the following case?
A technician is installing updates on a Windows PC. Some of the upgrades go through without a hitch, while others show up as unsuccessful. The technician restarts the PC and tries to install the unsuccessful updates again while troubleshooting. The upgrades keep failing.

The error number will provide the technician with specific information about the cause of the failure. This information can then be used to troubleshoot the problem and find a solution. The other options are also important, but they should be checked later in the troubleshooting process. For example, if the technician is unable to resolve the problem by looking up the error number, they can then try downloading the failed update to install manually.
