Preview Rollup Updates are optional, quasi for testing, their content will be released on the following regular patchday.
I noticed that the preview rollup updates were not released on the 3rd or 4th Tuesday of the month, but in the 4th week of April with a few days delay. The KB articles also contain a warning of known issues related to third-party antivirus solutions. Users had already observed these problems in connection with the security updates of April 9, 2019.
Updates for Windows 7/Windows Server 2008 R2
preview rollup update has been released for Windows 7 SP1 and Windows Server 2008 R2 SP1. The update history for Windows 7 can be found on this Microsoft page.
KB4493453 (Preview Monthly Rollup) Windows 7/Windows Server 2008 R2
Update KB4493453 (Preview Rollup for Windows 7 SP1 and Windows Server 2008 R2 SP1) contains improvements and bug fixes that will be rolled out in the following month. The KB article points out that this update no longer includes the PciClearStaleCache.exe for fixing network problems. If you encounter problems, please see KB4493453 for more information. The update addresses for the umpteenth time the problem that the Japanese calendar received a new calendar on May 1, 2019 according to the following list. Here are the details:
- Addresses an issue that prevents the CALDATETIME structure from handling more than four Japanese Eras. For more information, see KB4469068.
- Updates the NLS registry to support the new Japanese Era. For more information, see KB4469068.
- Addresses an issue that causes the DateTimePicker to display the date incorrectly in the Japanese date format. For more information, see KB4469068.
- Addresses an issue that causes the Date and Time Settings control to cache old Eras and prevents the control from refreshing when the time enters the new Japanese Era. For more information, see KB4469068.
- Updates fonts to support the new Japanese Era. For more information, see KB4469068.
- Addresses an issue that prevents an input method editor (IME) from supporting the new Japanese Era character. For more information, see KB4469068.
- Addresses an issue that causes the Clock and Calendar flyout control to display the day of the week incorrectly mapped to a date in the month of the new Japanese Era. For more information, see KB4469068.
- Adds alternative fonts for the new Japanese Era fonts. For more information, see KB4469068.
The update is automatically downloaded and installed by Windows Update. It can also be downloaded from Microsoft Update Catalog. Microsoft strongly recommends that you install the latest Service Stack Update (SSU) KB4490628 before installing the latest rollup. With Windows Update, the SSU is automatically offered before the installation.
Since this is a preview rollup, I would hide it unless there are special requirements for testing. Background is also that the preview rollup update has several known issues:

After installing this update, some customers report that authentication fails for services that require unrestricted delegation after the Kerberos ticket expires (default is 10 hours). For example, the SQL Server service fails.
Microsoft also mentions other issues related to Sophos, Avira, Avast, ArcaBit and Mc Afee antivirus solutions, which caused trouble with the April 9, 2019 security update.
Microsoft is investigating the issues with AV solutions in collaboration with their vendors. The KB article contains hints and links to the support articles of the AV manufacturers.
Updates for Windows 8.1/Windows Server 2012 R2
A preview rollup update has been released for Windows 8.1 and Windows Server 2012 R2. The update history for Windows 8.1 can be found on this website.
KB4493443 (Preview Monthly Rollup) Windows 8.1/Windows Server 2012 R2
Update KB4493443 is available for Windows 8.1 and Windows Server 2012 R2 as Preview of Monthly Rollup. This is not a security update. The preview rollup addresses the same issues as Windows 7 update KB4493453 (see above). This update is automatically downloaded and installed by Windows Update. It can also be downloaded from the Microsoft Update Catalog.
I recommend: The preview rollup should be hidden and not installed unless there are special testing requirements. This is because the Preview Rollup Update has also the same issues with third-party antivirus solutions described in the above Windows 7 Preview Rollup Update.
After installing this update you may also experience problems with the Preboot Execution Environment (PXE). This occurs when you need to boot a device from a Windows Deployment Services (WDS) server that is configured to use the Window Extension variable. This may cause the connection to the WDS server to terminate prematurely during the download of the (operating system image). This issue does not affect clients or devices that do not use a Window Extension variable.
Also, certain operations, such as renaming files or folders located on a cluster shared volume (CSV), may fail with the error "STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5)". This occurs when you perform the action on a CSV owner node from a process that does not have administrator privileges.
