A recent Windows security update has led to the creation of a new folder called inetpub on many users’ computers. This folder began appearing after Microsoft rolled out important system patches in May 2025. Although the folder is safe, its sudden appearance has caused confusion among users. Microsoft included it as part of a broader effort to improve system protection.
The inetpub folder is not new. It has been used for years as part of Microsoft’s Internet Information Services (IIS), which helps manage web servers. Most regular users never saw this folder before because it was only used in special cases. Now, due to the latest updates, the folder has started showing up more often, even for users who are not running web servers.
The folder was added to support new security tools. Microsoft’s update focused on fixing web-based threats that could affect the system. To make this work, the operating system needed to create the inetpub folder so it could store some background files. These files help Windows manage web connections in a safer way.
Some users may think the inetpub folder is unnecessary and may want to delete it. However, experts say this is not a good idea. Deleting the folder could cause serious problems. It might affect the way your computer runs. Certain tools or apps may stop working. Also, future updates may not install correctly if the folder is missing.
The folder may also be used for parts of Microsoft’s security features. If it is deleted, your computer might become more open to threats. That’s why it is best to leave the folder alone. It is not taking up much space, and it is not harmful.
If you find the inetpub folder on your system, there is no reason to panic. First, make sure your system is up to date by checking Windows Update. Second, do not delete or move the folder. Third, scan your computer using a trusted antivirus program to make sure everything else is fine. Finally, if you are still unsure, you can visit Microsoft’s official support website for more details.
Some users noticed the folder right after installing the latest Windows security updates. In most cases, the folder appears in the main system drive, usually labeled C:\inetpub. If you check the folder’s properties, it will likely show the same date as the last update. This confirms that it was created by the system and not by a third-party app.
Online discussions show that people are divided. Some welcome the extra protection, while others are confused by the sudden change. But system administrators and tech experts agree that the folder is safe and should not be removed. It is a sign that Microsoft is actively improving Windows security in response to online threats.
There are other folders like inetpub that also appear during updates. These include folders like ProgramData and PerfLogs. All of them help Windows perform better and stay secure. They are hidden most of the time, but they are not dangerous.
In summary, the inetpub folder is part of the latest Windows security update. It helps protect your system from online attacks and supports important system features. Deleting it could cause problems and reduce your computer’s safety. If you see it, leave it alone and keep your system updated.
