If you have ever browsed the contents of your Windows installation media or the recovery partition on your PC, you may have come across a file called install.wim. This file is an essential part of the Windows setup process, but it can also take up a lot of space on your disk. In this blog post, we will explain what install.wim is, whether it is malware, and whether you should remove it or not.

What is Install.wim?
Install.wim stands for Windows Imaging Format, and it is a file-based disk image format that Microsoft uses to deploy Windows operating systems. A disk image is a single file that contains all the data and settings of a disk, such as partitions, files, folders, boot information, etc. Install.wim contains the disk image of the Windows edition that you want to install on your PC. For example, if you have a Windows 10 Home installation media, install.wim will contain the disk image of Windows 10 Home.
Is Install.wim malware?
Install.wim is not malware, and it is a legitimate file that belongs to Microsoft. However, some malware may disguise themselves as install.wim or use the same name to trick users into thinking that they are harmless. Therefore, you should always check the location and size of install.wim before deleting it or opening it. The genuine install.wim file should be located in the sources folder of your Windows installation media or recovery partition, and it should be around 3-4 GB in size. If you find an install.wim file in another location or with a different size, you should scan it with Malwarebytes Anti-Malware to make sure that it is not infected.
Should I remove Install.wim?
Install.wim is necessary for installing or repairing Windows on your PC, so you should not remove it if you plan to use your Windows installation media or recovery partition in the future. However, if you have already installed Windows and you do not need to reinstall or repair it, you can delete install.wim to free up some space on your disk. To do so, you can use a tool like Disk Cleanup or WinDirStat to find and delete install.wim from your PC. Alternatively, you can also compress install.wim using a tool like DISM or 7-Zip to reduce its size without deleting it.
Conclusion
Install.wim is a disk image file that contains the Windows operating system that you want to install on your PC. It is not malware, but you should always verify its location and size before opening or deleting it. You can keep install.wim if you want to use your Windows installation media or recovery partition in the future, or you can delete or compress it if you want to save some disk space.
How to Stay Safe Online
Here are 10 basic security tips to help you avoid malware and protect your device:
Use a good antivirus and keep it up-to-date.
It's essential to use a good quality antivirus and keep it up-to-date to stay ahead of the latest cyber threats. We are huge fans of Malwarebytes Premium and use it on all of our devices, including Windows and Mac computers as well as our mobile devices. Malwarebytes sits beside your traditional antivirus, filling in any gaps in its defenses, and providing extra protection against sneakier security threats.
Keep software and operating systems up-to-date.
Keep your operating system and apps up to date. Whenever an update is released for your device, download and install it right away. These updates often include security fixes, vulnerability patches, and other necessary maintenance.
Be careful when installing programs and apps.
Pay close attention to installation screens and license agreements when installing software. Custom or advanced installation options will often disclose any third-party software that is also being installed. Take great care in every stage of the process and make sure you know what it is you're agreeing to before you click "Next."
Install an ad blocker.
Use a browser-based content blocker, like AdGuard. Content blockers help stop malicious ads, Trojans, phishing, and other undesirable content that an antivirus product alone may not stop.
Be careful what you download.
A top goal of cybercriminals is to trick you into downloading malware—programs or apps that carry malware or try to steal information. This malware can be disguised as an app: anything from a popular game to something that checks traffic or the weather.
Be alert for people trying to trick you.
Whether it's your email, phone, messenger, or other applications, always be alert and on guard for someone trying to trick you into clicking on links or replying to messages. Remember that it's easy to spoof phone numbers, so a familiar name or number doesn't make messages more trustworthy.
Back up your data.
Back up your data frequently and check that your backup data can be restored. You can do this manually on an external HDD/USB stick, or automatically using backup software. This is also the best way to counter ransomware. Never connect the backup drive to a computer if you suspect that the computer is infected with malware.
Choose strong passwords.
Use strong and unique passwords for each of your accounts. Avoid using personal information or easily guessable words in your passwords. Enable two-factor authentication (2FA) on your accounts whenever possible.
Be careful where you click.
Be cautious when clicking on links or downloading attachments from unknown sources. These could potentially contain malware or phishing scams.
Don't use pirated software.
Avoid using Peer-to-Peer (P2P) file-sharing programs, keygens, cracks, and other pirated software that can often compromise your data, privacy, or both.
To avoid potential dangers on the internet, it's important to follow these 10 basic safety rules. By doing so, you can protect yourself from many of the unpleasant surprises that can arise when using the web.
