Avoid a Wormable Attack: Download the BlueKeep Patch for Windows 7 Now
How to Download and Install the BlueKeep Patch for Windows 7
If you are still using Windows 7, you may be at risk of a serious security vulnerability called BlueKeep. This vulnerability can allow hackers to remotely access and control your system, and even spread malware to other computers on your network. In this article, we will explain what BlueKeep is, how to check if your system is vulnerable, and how to download and install the patch that fixes it.
What is BlueKeep and Why Should You Care?
BlueKeep is a serious security vulnerability that affects older versions of Windows
BlueKeep, also known as CVE-2019-0708, is a security flaw that was discovered in Microsoft's Remote Desktop Protocol (RDP) implementation. RDP is a feature that allows you to connect to another computer over a network or the internet. BlueKeep affects all unpatched Windows NT-based versions of Windows from Windows 2000 to Windows Server 2008 R2 and Windows 7.

BlueKeep can allow remote code execution and wormable attacks
BlueKeep is classified as a "wormable" vulnerability, meaning that it can be exploited without any user interaction or authentication. A hacker can send specially crafted packets to an RDP-enabled system and execute arbitrary code on it. This code can then perform malicious actions, such as stealing data, installing malware, or creating backdoors. Moreover, the code can also scan for other vulnerable systems on the same network or the internet, and infect them as well. This can create a large-scale outbreak of cyberattacks, similar to what happened with Conficker and WannaCry in the past.
BlueKeep has been patched by Microsoft, but many users have not updated their systems
Microsoft issued a security patch for BlueKeep on May 14, 2019, as part of its monthly update cycle. The patch includes an out-of-band update for several versions of Windows that have reached their end-of-life, such as Windows XP. Microsoft strongly recommends that all users apply the patch as soon as possible, as it is the only way to prevent exploitation of the vulnerability. However, many users have not updated their systems yet, either because they are unaware of the threat, or because they have disabled automatic updates. According to some estimates, there are still millions of devices that are vulnerable to BlueKeep.
How to Check If Your Windows 7 System Is Vulnerable to BlueKeep
You can use a free tool called RDPScan to scan your system for the vulnerability
One of the easiest ways to check if your system is vulnerable to BlueKeep is to use a free tool called RDPScan. This tool was developed by Robert Graham, a security researcher who also created Mass Scan, a tool that can scan the internet for vulnerable devices. RDPScan is a command-line tool that you can download from GitHub and run on your system. It will scan your local IP address and tell you if your system is vulnerable, patched, or not listening for RDP connections. You can also scan other IP addresses or ranges to check for other devices on your network or the internet.
You can also check the version of your Remote Desktop Protocol (RDP) service
Another way to check if your system is vulnerable to BlueKeep is to check the version of your RDP service. You can do this by opening the Services app on your system and looking for the Remote Desktop Services entry. Right-click on it and select Properties. Then, go to the General tab and look at the Path to executable field. You will see a file name that ends with termsrv.dll and a number that indicates the version of the file. If the number is lower than 6.1.7601.24441, then your system is vulnerable and needs to be patched. If the number is equal to or higher than 6.1.7601.24441, then your system is patched and safe from BlueKeep.

You can also check if you have Network Level Authentication (NLA) enabled for RDP
A third way to check if your system is vulnerable to BlueKeep is to check if you have Network Level Authentication (NLA) enabled for RDP. NLA is a feature that requires users to authenticate themselves before establishing an RDP connection. This can prevent unauthenticated attackers from exploiting BlueKeep, as they will not be able to send malicious packets to the RDP service. However, NLA is not a complete solution, as it can be bypassed by some techniques, such as credential theft or relay attacks. Therefore, you should still patch your system even if you have NLA enabled. To check if you have NLA enabled, you can go to the Control Panel and open the System app. Then, go to the Remote settings tab and look at the Remote Desktop section. If you see a checkbox that says "Allow connections only from computers running Remote Desktop with Network Level Authentication", then you have NLA enabled. If not, then you don't have NLA enabled and you are more vulnerable to BlueKeep.
How to Download and Install the BlueKeep Patch for Windows 7
You can download the patch from the Microsoft Update Catalog website
The official way to download and install the BlueKeep patch for Windows 7 is to use the Microsoft Update Catalog website. This website contains all the updates that Microsoft has released for its products, including security patches. You can search for the patch by using its KB number, which is KB4499175 for Windows 7 32-bit and KB4499175 for Windows 7 64-bit.

You may need to restart your computer after installing the patch.
You can also use Windows Update to install the patch automatically
Another way to download and install the BlueKeep patch for Windows 7 is to use Windows Update, which is a built-in feature that automatically downloads and installs updates for your system. To use Windows Update, you need to have automatic updates enabled on your system, which is recommended by Microsoft for security reasons. You can check if you have automatic updates enabled by going to the Control Panel and opening the Windows Update app. Then, go to the Change settings tab and look at the Important updates section. If you see a dropdown menu that says "Install updates automatically (recommended)", then you have automatic updates enabled. If not, then you can change it to enable automatic updates.
If you have automatic updates enabled, then Windows Update will download and install the BlueKeep patch for you in the background, without any user intervention. However, this may tak
