+### Special case of error code 0x800705aa - Registry size limit

+Error code 0x800705aa might indicate an issue that involves the registry instead of a general virtual memory issue. To see if this is the case, check the CBS.log file for entries that resemble the following example:

+In most cases, this issue occurs if the computer or virtual machine (VM) doesn't have enough available virtual memory for Windows to install the update. The most common causes of this issue are the following conditions:
 
 - Third-party applications are consuming lots of virtual memory.
 - The computer's virtual memory isn't managed automatically. Instead, it's manually configured.
 
+If the CBS log indicates that the issue involved registry resources, the `RegistrySizeLimit` registry entry is set to a value other than **0**. This value restricts the registry's maximum size. When the registry size grows to meet the configured limit, Windows can't perform necessary servicing activities, such as updates.
+
 ## Workaround: Clean restart
 
 When you start Windows by using a normal startup, several applications and services start automatically, and then they run in the background. These programs include basic system processes, antivirus software, and system utility applications. These applications and services can interfere with the update process.
