To optimize your system’s performance and free up valuable storage space, it’s essential to use tools like Wicleanup to delete MSP files and other unnecessary data.

Solid State Drives (SATA and NVMe) are fast becoming the norm for many users to place their Windows install onto. Because prices for larger capacity drives are still quite expensive, many users have smaller capacity drives. If you have a smaller SSD or your Windows boot partition isn’t that large, you need to watch every Gigabyte that goes onto it or space can fill up pretty quickly.

Using tools like TreeSize or SpaceSniffer to find what is taking up excess space on your drive might show that the C:\Windsows\Installer folder is one of them. If you check the folder, you will most likely find a lot of MSI and MSP files in there possibly consuming Gigabytes of drive space. Do note that the Windows Installer folder has a hidden and system attribute. To see the folder, you will need to select “Show hidden files, folders and drives” and uncheck “Hide protected operating system files” from the Folder Options in Control Panel.

Here are a few ways in which you can more safely identify and delete redundant MSI and MSP files from the Windows Installer folder.

Use the IObit Uninstaller Tool

The IObit Uninstaller is a powerful third-party program that allows users to wipe files from the installer folder. This feature is particularly useful since computer owners usually cannot remove the Windows install folder through the built-in Windows Control Panel. First, the program uses a “Powerful Scan” to identify any left-over entries and files that are in the install folder. Once the scan is complete, the application prompts the user to uninstall these files.

Additionally, you can open the IObit software > click on Tools > and choose Easy Uninstall as an easier alternative. After choosing easy uninstall, drag the icon to the open folder you wish to delete and watch the app automatically erase that file. The IObit Uninstaller is a great tool for users with little technical know-how and users who want to save time. Furthermore, this Uninstaller can uninstall residual files in batches for free. Users can also look through their uninstall history to check on the progress of their uninstallation.

Download IObit Uninstaller

Patch Cleaner is specifically designed to clean redundant files from the Installer folder and the tool actually took its inspiration from this very article! Attribution to Raymond.cc is on the about page (thanks HomeDev for the mention). Patch Cleaner appeared in 2015 but there’s been no updates since 2016, so it’s safe to say the program is no longer in development. Both portable and installer versions are available.

Simply launch the tool and it will run a scan and show the results in the window of what has been found. The files still used result is what it believes should be kept and the orphaned files are what can be removed because they are no longer required by any installed software. A Windows install that’s been in use for several years could show several Gigabytes of orphaned files.

If you have adequate space on another drive, it’s best to use the included option and move the files instead of directly deleting them. That way, if you run into a problem, you still have a backup as this process is by no means foolproof. Use the Browse button to locate a destination folder. If you want to ignore MSI or MSP files connected to specific software, an exclusion can be created in the Settings.

Patch Cleaner requires .NET Framework 4.5.2 or newer so Windows 7 users will need to make sure their installed .NET versions include it. Patch Cleaner works on Windows 7, 8, 10, and Server 2008/2012.

Use an old Microsoft Utility

One of the old tools that could do this was MsiZap which was developed by Microsoft. The tool is available with The Windows Installer Clean Up Utility (Msicuu) which is basically a frontend for some of MsiZap’s commands. Microsoft discontinued both MsiZap and Msicuu some time ago after saying they were causing too many issues, but many users still use MsiZap with some success. Download the Windows Installer Clean Up Utility and then extract it with 7-Zip to use the MsiZapU.exe.

Open a Command Prompt, type MsiZapU.exe G and press enter. The G command tells the program to remove any orphaned cached Windows Installer data files. While testing we got an error on both Windows 7 and XP similar to the following although it did say it had cleared some orphaned files out.

MsiZapInfo: Performing operations for user S-1-5-21-598190838-2299067166-971484642-1000
Removing orphaned cached files.
Error enumerating Products key for S-1-5-21-598190838-2299067166-971484642-1000 user. Error: 6.
FAILED to clear all data.

MsiZap is definitely a tool to be used with caution because Microsoft usually doesn’t pull utilities unless there’s a valid reason to do so.

The Windows Installer UnUsed Files Cleanup Tool (WICleanup) by KZTechs is able to scan for orphaned MSI and MSP files in the WindowsInstaller folder and offers you an option to delete them from the comfort of a graphical user interface. For scripts and command line usage, WICleanup also includes a command line version in the archive (WICleanupC.exe).

Картинка с сайта: whatsoftware.com

All you need to do is extract the downloaded ZIP file, run the WICleanupUI.exe and click the Scan button. All the entries that show in the window are orphaned files and manually check the boxes for what you want to delete. Although it has no option to automatically select all files for deletion, you can use the Shift key to multi-select, i.e; click the first file, hold Shift and click the last file, then click one of the selected tick boxes. It would have been useful if this tool offered an option to backup the unused files instead of deleting them in case of any potential problems. Note the website is in Japanese.

Deleting the Unused MSI Entries Manually

Before you simply go into the C:\Windows\Installer folder and start deleting files on your own to free up some space, there is a way to determine which files are orphaned and should be safe to delete. Because the patch files still registered will have a corresponding entry in the registry, those that are missing aren’t necessary anymore.

Heath Stewart over at blogs.msdn.com wrote a small VBScript a few years back that checks the system for registered patch files, and lists those that are. This way you will be shown the files that you SHOULD NOT delete from WindowsInstaller as they are the ones still in use, those not in the list are safe to remove.

Download WiMsps VBScript

Do note that this download isn’t the original VBScript found on the website as that has an annoying OK popup on every registered entry it comes across which can be very annoying because there’s often loads of them. We’ve made a minor modification to output the registered entries to a text file instead.

Картинка с сайта: whatsoftware.com

Don’t forget, these are the currently registered patch files and the ones to not touch. We would recommend you don’t manually delete files from the Installer folder anyway without some experience, and moving them to another folder just in case a problem occurs is more preferable.

If you have ever installed a program and realized you didn’t need it or the app installation failed, you might be aware of the Windows Installer Cleanup utility. 

This tool was available in earlier versions of Windows, but we show you how you can still download it in newer versions.

What does Windows Installer Cleanup Utility do? 

Windows Installer Cleanup Utility is a tool that helps you to remove invalid registry entries and other system garbage. Such files can cause your PC to run extremely slow and other performance issues.

By using this utility, you can scan your computer for known issues and repair them. The utility also provides a way to uninstall programs that were installed on your computer by using Windows Installer technology. 

Other beneficial purposes it may serve include:

• Clears out any orphaned registry keys related to previous installations of applications that use Windows Installer technology.
• Uninstall applications from your PC that cannot be uninstalled normally, such as those where the uninstaller is corrupted or missing altogether.
• Cleans up temporary files after uninstalling an application and recovers the disk space. 

How can I download the Windows Installer Cleanup utility?

Before you download the Windows Installer Cleanup utility, there are a few things to note:

• Microsoft has shelved the tool and stopped offering it for download. 
• The tool is free to download, and you can still use the utility, but Microsoft will no longer update it.
• The utility was built for earlier versions of Windows, so if you’re downloading it for newer versions, such as Windows 10 and 11, it may be incompatible or have some glitches.
• For newer Windows users, such as Windows 10 and 11, Microsoft replaced the Windows Installer Cleanup utility with the Microsoft Fixit tool but later discontinued it.
• Since the tool was discontinued, it is no longer available on the official Microsoft site, so you’ll have to download it from third-party sites.
• Because a lot of these sites are untrustworthy, ensure your system is backed up by a reliable antivirus before downloading it.

Now, to download it, follow the steps below:

1. Launch your browser and download the Windows Cleanup Utility tool.
2. Open the file location, right-click on it, and select Open to launch the .exe file.

Is it safe to delete the Windows Installer folder?

The Windows Installer folder is a hidden folder that contains all the Windows Installer data for your system. It can get pretty large if you have a lot of programs installed on your computer because it includes files and registry keys. 

If you delete this folder, you’ll lose access to many applications. Instead of deleting the entire folder, we recommend performing a Disk Cleanup or finding other ways to free up space on your hard drive.

The good news is that other options are still available if you want to clean up your PC. Windows 11 has many built-in repair tools at your disposal. The program install and uninstall troubleshooter for Windows 11, for instance, is a replica of the Windows Installer Cleanup utility.

However, you may feel these tools are insufficient, so we recommend you reach out for uninstaller software. These tools will allow you to delete unnecessary files from your computer without worrying about causing future problems with your PC.

Let us know whether you still use the Windows Installer Cleanup utility and your experience thus far, especially in newer Windows versions.
