### Changes to Default Behavior in Cortex XDR Agent 7.4

The following topic describes changes to default behavior in Cortex XDR agent 7.4.

#### Feature

Performance Enhancements to Malware Scanning

(Windows)

#### Change to Behavior

As part of continuous improvements to the Cortex XDR agent performance, the agent scanning process was refactored to use a single thread that will limit the CPU consumption to a fixed percentage, depending on the number of processors the endpoint has. For example, on a 4-core endpoint, the CPU consumption is now limited to 25%.

#### Feature

Disk Encryption Behavior

(Windows)

#### Change to Behavior

If a Cortex XDR Disk Encryption profile is enforced on the endpoint, when you upgrade to the 7.4 release or later, the agent will first decrypt the drive on the endpoint and then encrypt it again.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/7.x/7.4-eol/changes-to-default-behavior-in-cortex-xdr-agent-7.4.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
