These preferences turn the Updater on and off.

• There are two bUpdater preferences: One for disabling services plugins and one for other product updates.
• DC Continuous track web and desktop updates are released in tandem to ensure cloud and desktop features and functionality remain synchronized and compatible. Failure to update desktop components while leaving services enabled may lead to an unsupported configuration. In other words, set both bUpdater preferences to the same value.
• Updater preferences in the UI have been changed to only show the "Auto" and "Off" options. The Continous track of Reader does not provide any UI options and the default is "Auto".
• Both bUpdater and Mode can be used to disable the Updater, but only bUpdater removes the update UI.
• Most other updater registry settings have been deprecated and only apply to 11.x and earlier.

Summary table

bUpdater	Disables the Updater and removes associated user interface items.
Check	Specifies the default time interval in hours to check for updates.
Mode	Specifies the Updater's update mode; for example, manual or automatic.

These preferences control when the updater is invoked, how and when a check for updates should be made, and other behaviors. Note that while the Updater is often disabled in enterprise settings, it's also possible to leave it enabled and configure whether updates happen automatically or silently.

For 12.x and later products, the web component updater can be configured independently of the product updater. Most of these preferences are deprecated and do not apply to 12.x and later products.

For an Updater Quick Key (not updated for 12.x and later products), refer to the Quick Key Library.

The log file is a file generated and appended to at runtime with status, operational, and error information describing what the Updater is doing. This information helps diagnose runtime problems and should be included with any support requests. Logging behaves as follows:

• Logging cannot be disabled.
• Log file size is not limited during an update.
• Log files are appended to each time the Updater runs, there is a 1MB limit on old logs.
• Log files are only backed up once; therefore, there should never be more than two logs on the system.
