Overview

The Remove Analysis features allow you to clean up and remove analysis data that xAnalyzer has added to your code. This is useful when you want to re-analyze code with different settings, remove outdated analysis, or simply start fresh.
Removing analysis does not affect the actual code or executable - it only removes the comments, labels, and other annotations that xAnalyzer added during analysis.

​
Available Removal Options

xAnalyzer provides three removal scopes that mirror the analysis options:

​
Remove Analysis from Selection

Removes analysis data only from the currently selected instructions in the disassembly window.

​
Remove Analysis from Function

Removes all analysis data from the entire function containing your current instruction.

​
Remove Analysis from Module

Removes all analysis data from the entire module, clearing all xAnalyzer comments and labels.

​
How to Remove Analysis Data

​
Using the Context Menu

1

Select your scope

Depending on what you want to remove:
  • For selection removal: Select the instructions you want to clean
  • For function removal: Click any instruction within the function
  • For module removal: Click anywhere in the module
2

Open context menu

Right-click to open the context menu in the disassembly window.
3

Choose remove option

Navigate to Plugins → xAnalyzer → Remove Analysis, then select:
  • Remove Analysis from Selection
  • Remove Analysis from Function
  • Remove Analysis from Module
4

Confirm removal

The analysis data will be removed immediately. Check the log window for confirmation.

​
Using Commands

You can use the x64dbg command line to remove analysis data: 
# Remove analysis from selection
xanalremove selection

# Remove analysis from function
xanalremove function

# Remove analysis from module
xanalremove module
Commands can be useful when scripting or automating your analysis workflow.

​
Using Hotkeys

Set up keyboard shortcuts for faster access:
1

Open shortcuts settings

Go to Options → Preferences → Shortcuts in x64dbg.
2

Find remove commands

Search for the xAnalyzer remove analysis commands.
3

Assign hotkeys

Set your preferred keyboard shortcuts for each removal option.
4

Apply and use

Save the settings and use your hotkeys to quickly remove analysis.

​
What Gets Removed

When you remove analysis, xAnalyzer cleans up:

​
Auto Comments

  • Function argument descriptions
  • API call prototypes
  • Data type information
  • Parameter values and names
  • Loop markers and labels

​
Auto Labels

  • Loop entry/exit labels
  • Function call labels
  • Data reference labels
  • Jump destination labels

​
Clear Behavior

The removal respects your configuration settings: Clear Auto Comments: When enabled, removes all automatic comments added by xAnalyzer. Clear Auto Labels: When enabled, removes all automatic labels added by xAnalyzer. Clear User Comments: When enabled, also removes user-added comments (use with caution!). Clear User Labels: When enabled, also removes user-added labels (use with caution!).
Be careful with the “Clear User” options! These will remove comments and labels that you manually added, not just xAnalyzer’s automatic additions.

​
Configuration Options

Configure what gets removed during cleanup:
1

Open xAnalyzer options

Navigate to Plugins → xAnalyzer → Options.
2

Configure clear options

Toggle these options based on your needs:
  • Clear Auto Comments: Remove xAnalyzer’s automatic comments
  • Clear Auto Labels: Remove xAnalyzer’s automatic labels
  • Clear User Comments: Remove manually added comments (careful!)
  • Clear User Labels: Remove manually added labels (careful!)
3

Save settings

Settings are saved automatically and will be used for all subsequent removal operations.

Example: Before and After Removal

Before removal (with xAnalyzer analysis): 
push 0          ; uType = MB_OK
push 403000     ; lpCaption = "Error"
push 403010     ; lpText = "An error occurred"
push 0          ; hWnd = NULL
call <user32.MessageBoxA>  ; MessageBoxA(hWnd, lpText, lpCaption, uType)
test eax, eax               ; Check return value
jne short loc_401020        ; Jump if not zero
loc_401020:                 ; [LOOP END]
After removal: 
push 0
push 403000
push 403010
push 0
call <user32.MessageBoxA>
test eax, eax
jne short loc_401020
loc_401020:
The code returns to its original state without xAnalyzer’s annotations.

​
Common Use Cases

​
Re-analyzing with Different Settings

1

Remove old analysis

Use Remove Analysis from Module to clear existing data.
2

Change settings

Adjust xAnalyzer configuration options (e.g., enable Analyze Undefined Functions).
3

Re-analyze

Run Analyze Module again with the new settings.

​
Cleaning Specific Functions

When you want to manually document a function but xAnalyzer’s comments are in the way:
1

Position cursor

Click on any instruction within the function.
2

Remove function analysis

Use Remove Analysis from Function.
3

Add manual comments

Add your own comments and labels without xAnalyzer’s automatic additions.

​
Selective Cleanup

For partial cleanup of a selection:
1

Select instructions

Highlight the specific instructions you want to clean.
2

Remove selection analysis

Use Remove Analysis from Selection.
3

Keep surrounding analysis

The rest of your analysis data remains intact.

​
Best Practices

Save your work before removing: If you’ve done extensive manual documentation alongside xAnalyzer’s analysis, consider saving your x64dbg database before removing analysis data.
Test with selection first: When unsure about what will be removed, test with Remove Analysis from Selection on a small section first before removing from an entire function or module.
Configure clear options carefully: Review the clear options in xAnalyzer settings before performing large-scale removals to ensure you don’t accidentally delete your own comments or labels. Use removal before re-analysis: When changing xAnalyzer settings significantly, remove the old analysis first to avoid confusion from overlapping or conflicting annotations. Check the log: After removal, check the x64dbg log window for confirmation messages and any warnings about what was removed.

​
Removal vs. Re-analysis

  • Changing major configuration options (e.g., enabling Extended Analysis)
  • Switching between defined and undefined function analysis
  • Starting a fresh analysis session
  • Creating manual documentation
  • Minor setting adjustments
  • When “Clear Auto Comments/Labels” options are enabled
  • Quick iterative analysis during debugging
  • When you want to preserve some existing annotations

​
Limitations

Removal operations cannot be undone. Make sure to save your x64dbg database before removing analysis if you might want to restore it later.
Database impact: Removal affects the current session and will be saved if you save the x64dbg database. Reload the database to restore removed analysis from a previous save. User data protection: When “Clear User Comments/Labels” options are disabled (default), your manual annotations are preserved during removal. Nested data: Some complex analysis patterns may leave residual markers if removal is interrupted or encounters errors.
