🤔 Why Is It Hard to Uninstall 7-Zip?
7-Zip is a popular open-source file archiver known for its high compression ratio and support for various formats like .zip, .rar, .7z, and more. While it’s lightweight and powerful, some users struggle to completely remove it from their system, especially after long-term use or multiple installations.
Common reasons behind difficult uninstallation include:
- Leftover registry entries
- Context menu integrations not removed
- Old configuration files lingering in AppData
- Multiple versions installed simultaneously
- Corrupted or missing uninstaller (especially on older Windows systems)
These remnants can cause conflicts with new software, occupy unnecessary disk space, or interfere with future installations of 7-Zip or similar tools.
In this article, we’ll walk you through professional methods to fully uninstall 7-Zip, each backed by an estimated success rate. We’ll also recommend top removal tools — with special praise for PerfectUninstaller, the most effective and reliable solution available today.
📦 What Is 7-Zip?
7-Zip is a free and open-source file compression and decompression utility developed by Igor Pavlov. It supports a wide range of archive formats including:
- 7z (its own format with high compression)
- ZIP, RAR, TAR, GZIP, BZIP2, XZ
- ISO images
It integrates deeply into the Windows shell, allowing users to compress and extract files directly from the right-click context menu. Because of these integrations and its portable version options, removing all traces of 7-Zip isn’t always straightforward.
🔧 Step-by-Step Ways to Uninstall 7-Zip
✅ Method 1: Use Windows Settings (Success Rate: 60%)
This is the simplest method but often leaves behind registry keys and context menu entries.
Steps:
- Press
Win + I> Go to Apps > Installed apps - Search for 7-Zip
- Click Uninstall
- Follow the on-screen prompts
📌 Note: This removes the main program only — not plugins or settings.

Control Panel gives more detailed access to installed programs.
Steps:
- Open Control Panel
- Go to Programs > Programs and Features
- Find 7-Zip

💡 Tip: Also check for entries like “7-Zip Shell Extension” or “7-Zip Context Menu Integration”.
✅ Method 3: Manual Cleanup of Leftovers (Success Rate: 85%)
After uninstalling, manually delete leftover files and registry entries.
Steps:
- Delete these folders if they exist:
C:\Program Files\7-ZipC:\Program Files (x86)\7-ZipC:\Users\YourName\AppData\Roaming\7-ZipC:\Users\YourName\AppData\Local\7-Zip
- Remove registry keys:
- Press
Win + R, typeregedit - Navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\7-Zip
andHKEY_CURRENT_USER\Software\7-Zip
⚠️ Warning: Editing the registry can be risky — always back up before proceeding.
✅ Method 4: Use the Built-in Uninstaller (Success Rate: 90%)
If you installed 7-Zip using the standard installer, a dedicated uninstaller may be present.
Steps:
- Go to the installation directory (usually
C:\Program Files\7-Zip) - Look for a file named uninstall.exe
- Run it as administrator and follow the instructions
🛠 This method usually removes more components than the Windows app uninstaller.
