Windows 10, version 1703, reached end of service on October 8, 2018.

To continue receiving security and quality updates, Microsoft recommends updating to the latest version of Windows 10.
IMPORTANT: Windows 10 Enterprise and Windows 10 Education editions will receive one year of additional servicing at no cost.

Windows Update Improvements
Microsoft has released an update directly to the Windows Update client to improve reliability. Any device running Windows 10 configured to receive updates automatically from Windows Update, including Enterprise and Pro editions, will be offered the latest Windows 10 feature update based on device compatibility and Windows Update for Business deferral policy. This doesn't apply to long-term servicing editions.

Known issues in this update

Symptom	Workaround
Applications that use a Microsoft Jet database with the Microsoft Access 97 file format may fail to open if the database has column names greater than 32 characters. The database will fail to open with the error, “Unrecognized Database Format”.	Use one of the following options: Option 1: Modify the database to ensure that all column names are less than or equal to 32 characters. Option 2: Convert the database to the .accdb file format. To use the .accdb file format, you must change the Connection string after conversion. The easiest way to convert is to use Microsoft Access 2010 or earlier. Use Microsoft Access to open a database that has an older file format. You will be asked if you would like to convert. Click Yes and save the database with the .accdb extension. Option 3: Convert the database to a newer .mdb file format. This doesn’t require a change to the Connection string. Use Microsoft Access to open a database that has an older file format. You will be asked if you would like to convert. Click Yes and save the database with the .accdb file extension. Open the .accdb. From the File menu, click Save as and select Access 2002-2003 Database. Microsoft is working on a resolution and estimates a solution will be available early February.
[ADDED 1/16] After installing KB4480973, some users report that they cannot load a webpage in Microsoft Edge using a local IP address. Browsing fails or the webpage may become unresponsive.	Open the Control Panel and select Internet Options. On the Security tab, select the Trusted Sites icon. Select the Sites button. Clear the check box for Require server verification (https:) for all sites in this zone. In the Add this website to the zone: box, type the local IP address that failed to load, such as http://192.168.0.1. Select the Add button. Select the Require server verification (https:) for all sites in this zone check box. Select the Close button. Select the OK button. Restart Microsoft Edge. Microsoft is working on a resolution and will provide an update in an upcoming release.
