Here were the instructions I received from Microsoft via their email help. This solved my problem.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify
At this time, let's refer to the following steps to troubleshoot this issue.
Step 1: Backup the Registry
=====================
As we need to modify some registry keys to troubleshoot this issue, let?s perform the following steps to backup the current Registry first.
1. Click "Start", click "Run", type "regedit" (without quotations), and click "OK".
2. Select "My Computer" (the root node) in the left pane, click "Export" under the "File" menu, choose "All" under "Export" range, select "Desktop" in the "Save in" box, type "backup" in "File" Name, and then click "Save".
Please Note: The backup file is on the Desktop and named backup.reg. We can simply restore the registry by double-clicking the backup.reg file. After we have completed the troubleshooting and the issue has been resolved, we can delete this file.
3. Close the Registry Editor.
Then, proceed to Step 2.
Step 2: Restore the relevant Registry Key
===============================
1. Click "Start", "Run", type: "notepad C:\fix.reg" (without quotations) and press "Enter". Choose "Yes" when you are prompted.
2. Copy the following commands and then paste them into the opened Notepad window.
