ZaneBritt It sounds like you've encountered some interesting quirks while setting up Windows 10 on your Dell computers. Let's address each of your observations:
Windows Update Issue with KB34441: It's possible that the issue you encountered with the "Failure - Retry" message for KB34441 is specific to your system or configuration. While it's not uncommon for Windows Update to encounter errors or issues during the update process, the appearance of the hidden file $WINRE_BACKUP_PARTITION.MARKER is not likely related to this specific update problem. This file may be related to Windows recovery or backup features and may not be directly related to the update issue you're experiencing. It's worth exploring online forums or support communities to see if others have encountered similar update problems and if any solutions or workarounds have been suggessted.
Inability to Rename Desktop Icon: The inability to rename the Desktop icon labeled "This PC" is also an unusual behavior. Typically, users should be able to rename desktop icons without encountering any issues. However, it's possible that there may be a system or software-related restriction preventing the renaming of this particular icon. It's worth investigating whether there are any Group Policy settings or third-party software applications that may be affecting desktop icon behavior. Additionaly, you may want to try creating a new shortcut for "This PC" on the desktop and see if you're able to rename the new shortcut successfully.
Overall, these anomalies may require further investigation to determine the root cause and potential solutions. Exploring online forums, support communities, or reaching out to Microsoft support may provide additional insights and assistance in resolving these issues. Additionally, continuing to monitor system behavior and documenting any recurring issues can help identify patterns or common factors that may contribute to these anomalies.
