If the APPLY button in the PowerRename tool is greyed out, it typically indicates that there are no changes to apply. Here are a few things you can check to resolve this issue:

  1. Ensure Files are Selected: Make sure you have selected files in Windows File Explorer before right-clicking and choosing PowerRename. If no files are selected, the APPLY button will remain inactive.
  2. Search and Replace Values: Check that you have entered valid text in both the "Search for" and "Replace with" fields. If either field is empty, the APPLY button will be greyed out.
  3. Regular Expressions: If you are using regular expressions, ensure that the syntax is correct. Invalid regex can prevent the tool from functioning properly.
  4. Preview Pane: Look at the Preview pane to see if any files are being matched. If no files match the search criteria, the APPLY button will not be enabled.
  5. Filters: Check if any filters are applied that might be excluding the files you want to rename.

If you have checked all these points and the button is still greyed out, try restarting PowerToys or your computer to see if that resolves the issue.

    A possible reason of the Apply button still disabled, is that you have included into your rename some illegal characters, that cannot be present in file names. As example, do not use colon ':' or slashes. You may see that the rename is incorrect because at the left of each rename row a little red stop sign is present. The tooltip usually indicates what is wrong with the filename.

    You can safely replace all illegal characters with underscore and the Apply button will be enabled ready to do the job.
