(Freeware) Delete data in Windows permanently

Eraser is an advanced security tool for Windows which allows you to completely remove sensitive data from your hard drive by overwriting it several times with carefully selected patterns. Works with Windows 98, ME, NT, 2000, XP, Vista, Windows Server 2003 and Server 2008.

Eraser is Free software and its source code is released under GNU General Public License.

The program source is a .exe, we can unpackaged it into a .msi file and install the msi by using command with no user interactive. We can use this exe file via GPO deploy of this software.

And also, this software is support command line (not official support – may be support in the future) 


The Eraser’s default file erasure method – Gutmann is the most secure method of the program provide and it should be delete those data securely* (not able to recover)


The Gutmann method is an algorithm for securely erasing the contents of computer hard drives, such as files. Devised by Peter Gutmann and Colin Plumb, it does so by writing a series of 35 patterns over the region to be erased.


* There is currently no published evidence as to intelligence agencies' ability to recover files whose sectors have been overwritten, although published Government security procedures clearly consider an overwritten disk to still be sensitive.

Companies specializing in recovery of damaged media (e.g., media damaged by fire, water or otherwise) cannot recover completely overwritten files. No private data recovery company currently claims that it can reconstruct completely overwritten data.
