Solve 0xC0000005 with MAS: A Quick Fix Guide

Facing the dreaded 0xC0000005 error while trying to activate Windows or Office with Microsoft Activation Scripts (MAS)? Don't worry, this common issue is usually straightforward to fix. Let's get your system activated!

How to Solve 0xC0000005 MAS Activation Errors

Encountering error code 0xC0000005 during Windows or Office activation with Microsoft Activation Scripts (MAS) can be frustrating. This error typically indicates an “Access Violation,” meaning the program tried to access memory it wasn't allowed to. When it comes to MAS, this is almost always due to antivirus interference, as activation tools often perform actions that security software flags as suspicious.

Understanding the 0xC0000005 Error with MAS

MAS utilizes various activation methods like HWID, Ohook, TSforge, and Online KMS to achieve genuine activation. These methods involve modifying system files or registry entries, which are precisely the actions that antivirus programs are designed to prevent. Your antivirus, seeing these legitimate activation processes, mistakenly identifies them as threats and blocks them, leading to the 0xC0000005 error. It's not a flaw in MAS but a protective measure from your security software.

Steps to Resolve 0xC0000005

The solution to solve 0xC0000005 MAS errors is usually simple: temporarily disable your antivirus software. Before running MAS, pause or disable your antivirus and Windows Defender (including real-time protection and cloud-delivered protection). Once disabled, run MAS again. After successful activation, you can re-enable your antivirus. MAS is open-source and trusted by its community, so you can proceed with confidence. Remember, the download is a direct .cmd or .zip file with NO password required.

You can use the convenient PowerShell one-liner: irm https://get.activated.win | iex or download the .zip file.
