📜This script mitigates potential vulnerabilities in systems running older versions of 7-Zip (e.g., those affected by CVE-2025-0411) by completely disabling 7-Zip to prevent users from manually opening and extracting potentially malicious archives. It does so by removing 7-Zip from the context menu, blocking execution, and removing Start Menu shortcuts to ensure it cannot be accessed through Windows Search. The CVE-2025-0411 vulnerability in 7-Zip allows attackers to open and execute files inside archives without preserving the Mark-of-the-Web (MOTW) flag, potentially bypassing security restrictions. Since 7-Zip does not enforce MOTW, files extracted from an archive may execute without SmartScreen warnings, increasing the risk of exploitation. This script addresses the issue by: Removing 7-Zip as the default handler for .zip, .7z, and .rar files, ensuring Windows Explorer is used instead. Renaming 7-Zip executables (7zFM.exe, 7zG.exe, 7z.exe) to prevent manual execution. Applying NTFS execution restrictions to block users from running renamed copies of 7-Zip. Deleting 7-Zip shortcuts from the Start Menu to prevent launching it via Windows Search. Removing 7-Zip registry entries from Windows Search Index to ensure it does not appear in search results. 🚀 Disabling 7-Zip entirely mitigates vulnerabilities by preventing users from extracting or executing files through it, reducing the risk of exploitation. This approach is particularly useful in environments where immediate updating or patching of 7-Zip is not feasible. It ensures that users cannot unknowingly bypass security mechanisms while awaiting a proper update or alternative extraction method.

Valuable resources saved

"Before vRx, we would spend countless hours manually finding and verifying patches. We saved so much time (and headache!)."

Anonymous IT Operations Lead

IT Operations Lead

Third-party software patching is the most valuable feature.

"We have automated third-party patching on specific software, improving efficiency by 80%. vRx has reduced our patching time, which has improved our operations. It is more robust than other solutions because it offers better third-party remediation."

Billy Turner

VP, Managed Technology & Services

Single source of truth, capable of handling any application in our fleet

"vRx gives a single pane of glass to see what patches needed to go out and what sort of vulnerabilities we have on our Windows machines. Our meantime to remediate vulnerabilities has gone down by about 60% to 70%."

Peter Fallowfield

IT Manager

60% faster remediation, many hours saved

"Typically, with our previous solution of ManageEngine, it took about three hours to patch Windows Server, and now, that is less than an hour. It means less downtime for the business each month when we do patches."
