Solution 1Recommended

Reset Default Applications in Windows Settings

The quickest way to fix corrupted file associations is to reset your default apps in Windows Settings.

Windows allows you to easily restore the default programs for all file types. This will strip the incorrect Adobe Acrobat association from ZIP files and restore File Explorer as the default handler.

Open Windows Settings

Press the Windows key + I to open the Settings application, then navigate to the 'Apps' section.

Navigate to Default Apps

Click on 'Default apps' from the left-hand menu.

Reset to Microsoft Recommended Defaults

Scroll down to the bottom of the Default apps page and click the 'Reset' button under 'Reset to the Microsoft recommended defaults'.

Verify the ZIP File Association

Locate a ZIP file on your computer, right-click it, and verify that it now opens with File Explorer by default.

Reset Default Applications in Windows Settings

Quick Check: You can also scroll down in the Default Apps menu, click 'Choose default apps by file type', find '.zip', and manually select File Explorer.

Solution 2

Create a New Windows User Account

If resetting default apps doesn't work, your local user profile registry settings might be corrupted.

Frequently Asked Questions

Why are my ZIP files showing as PDF icons?

This happens when the .zip file extension gets mistakenly associated with a PDF reader, such as Adobe Acrobat, in your Windows default app settings or registry.

How do I get File Explorer back in the 'Open With' menu?

You can restore File Explorer by resetting your default apps in Windows Settings, or by manually browsing for 'explorer.exe' (located in C:\Windows) through the 'Choose another app' dialog.

Will resetting my default apps delete any of my personal files?

No, resetting default apps only changes which programs are used to open specific file types. Your personal files, photos, and data will remain perfectly safe and untouched.
