Hardentools simply reduces the attack surface on Microsoft Windows computers by disabling low-hanging fruit risky features. [hide][Hidden Content]]

Hardentools is a collection of simple utilities designed to disable a number of “features” exposed by operating systems (Microsoft Windows, for now), and primary consumer applications. These features, commonly thought for Enterprise customers, are generally useless to regular users and rather pose as dangers as they are very commonly abused by attackers to execute malicious code on a victim’s computer. The intent of this tool is to simply reduce the attack surface by disabling the low-hanging fruit. Hardentools is intended for individuals at risk, who might want an extra level of security at the price of some usability. It is not intended for corporate environments. What Hardentools IS NOT Hardentools is NOT an Antivirus. It does not protect your computer. It doesn't identify, block, or remove any malware. It does NOT prevent software from being exploited. It does NOT prevent the abuse of every available risky feature. It does NOT prevent the changes it implements from being reverted. If malicious code runs on the system and it is able to restore them, the premise of the tool is defeated. [hide][Hidden Content]]

WARNING: This is just an experiment, it is not meant for public distribution yet. Also, this tool disables a number of features, including of Microsoft Office, Adobe Reader, and Windows, that might cause malfunctions to certain applications. Use this at your own risk. Bear in mind, after running Hardentools you won’t be able, for example, to do complex calculations with Microsoft Office Excel or use the Command-line terminal, but those are pretty much the only considerable “downsides” of having a slightly safer Windows environment. Before deciding to use it, make sure you read this document thoroughly and understand that yes, something might break. In case you experience malfunctions as a result of the modifications implemented by this tool, please do let us know. Changelog v2.2 beta Changes since 2.1: UAC with password prompt now (see #46 ) now makes sure that all other UAC registry settings are set correctly (which they are by default) removed functionality in “restore” that deleted registry keys which have not been saved during harden. If you hardened your system with a (really) old version of hardentools, best first restore with an older version (<= 2.1) and then harden with this version again. [hide][Hidden Content]]
