Using multiple operating systems on a single computer is one of the most common things these days. The use of it serves many advantages to users, for example, if one of the operating systems becomes unbootable, you can continue computing with another and access your data files on that OS too. On the other hand, the release of new beta versions has made most of the users test them on separate HDD – thus again the parallel booting concept is used. One thing I have observed so far these days is that, when the users upgrade to a new edition of the operating system, they most probably look for removing the old edition.

Uninstall Windows OS

Meet NanWick Windows Uninstaller, which is a freeware to make your work easy in uninstalling Windows OS; It works just the way you uninstall any installed software. You can use this tool for the removal of Windows10/8/7/Vista from your computer, plus it is also helpful in uninstalling Windows preview versions.

This software is intended to delete the operating system related files from the machine followed by removal of the operating system’s entry at the boot menu. All the other files on the drive on which the operating system is installed will remain untouched. If you don’t want to let your libraries removed with the operating system along with your personal data on them, you can make a backup first from C:\Users\{username}.

How this tool works

The working procedure of this tool is stepwise. First of all, it takes up the ownership of the Windows folder in the system root directory. Then it takes up the ownership of some hidden files and folders in the system root directory listed below:

After taking ownership of the content mentioned above, it deletes them. So far, the operating system documents has been removed till now.

Finally, we have to root out its trace from the boot menu. For this, the tool utilizes the concept of BCDEDIT command. It executes bcdedit /delete <IDENTIFIER>. Here, you can easily find out the <IDENTIFIER> by executing bcdedit command in the administrative Command Prompt.

This removes the OS entry from the boot menu. So finally, the tool will have uninstalled Windows completely.

What you would have to do otherwise

To uninstall Windows, you simply need to do two steps. Firstly backup the data on the drive and format it using the Explorer. Then remove the entry from the boot menu using BCDEDIT command as explained above.
