 When you use [attack surface reduction rules](attack-surface-reduction.md) you might run into issues, such as:
 
-- A rule blocks a file, process, or performs some other action that it shouldn't (false positive)
-- A rule doesn't work as described, or doesn't block a file or process that it should (false negative)

+When setting up the attack surface reduction rules by using Group Policy, here are a few best practices to avoid making common mistakes:
 
-If these prerequisites are met, proceed to the next step to test the rule in audit mode.
+1. Make sure when adding the GUID for attack surface reduction rules, there are **no double quotes** (like this: "ASR Rules GUID") at the beginning or at the end of the GUID.

+2. Make sure that there are **no spaces** at the beginning or at the end when adding the GUID for attack surface reduction rules.
 
 ## Use audit mode to test the rule
 
 Follow these instructions in [Use the demo tool to see how attack surface reduction rules work](attack-surface-reduction-rules-deployment-test.md) to test the specific rule you're encountering problems with.
 
-1. Enable audit mode for the specific rule you want to test. Use Group Policy to set the rule to **Audit mode** (value: **2**) as described in [Enable attack surface reduction rules](enable-attack-surface-reduction.md). Audit mode allows the rule to report the file or process, but allows it to run.

-2. Perform the activity that is causing an issue (for example, open or execute the file or process that should be blocked but is being allowed).

+2. Perform the activity that is causing an issue. For example, open the file or run the process that should be blocked, but is allowed.

 If you've tested the rule with the demo tool and with audit mode, and attack surface reduction rules are working on preconfigured scenarios, but the rule isn't working as expected, proceed to either of the following sections based on your situation:
 
-1. If the attack surface reduction rule is blocking something that it shouldn't block (also known as a false positive), you can [first add an attack surface reduction rule exclusion](#add-exclusions-for-a-false-positive).

-2. If the attack surface reduction rule isn't blocking something that it should block (also known as a false negative), you can proceed immediately to the last step, [collecting diagnostic data and submitting the issue to us](#collect-diagnostic-data-for-file-submissions).

 ## Add exclusions for a false positive
 
 If the attack surface reduction rule is blocking something that it shouldn't block (also known as a false positive), you can add exclusions to prevent attack surface reduction rules from evaluating the excluded files or folders.
 
-To add an exclusion, see [Customize Attack surface reduction](attack-surface-reduction-rules-deployment-implement.md#customize-attack-surface-reduction-rules).
