If you’ve dealt with Windows Loader, we can safely assume your tech guys are pirating Windows 7. There’s no other need use for this tool except for the activation of Windows 7. We don’t support pirating Windows. Besides the intellectual property theft, it might result in lots of issues, deprive you of valuable updates etc. We explained everything below.

What’s the deal with the Unsupported partition table error?

Some of you might’ve tried pirating Windows 7. That’s hardly uncommon, as a lot of users got used some of the third-party tools to avoid Windows Activation or apply license keys. Microsoft even willingly allowed a free upgrade to Windows 10 for users who never spent a penny on Windows 7.

There is always a possible malware presence in all those pre-activated Windows 7 variations circulating online. Add possible system corruption after update installation and you’ll think twice before going for it.

With that in mind, most software pirates will install a standard version, skip on the activation, and use either Windows Loader or RemoveWAT tools to activate Windows 7.

Windows Loader is a common tool is a part of MSToolkit software specifically made to activate Microsoft products, like Windows or Microsoft Office. It basically uses a string of BIOS emulating actions to ‘trick’ Windows into activating.

However, some users who tried to run it were met with the “Unsupported partition table” error. This means WAT (Windows Activation Technology) detected it and prevented it from executing. We won’t provide you with any links but, if you know that the RemoveWAT tool exists, your next step should be clear.

Keep in mind that these tools are usually full of adware and come from suspicious sources, to say the least. With this tool, you should be able to activate Windows 7. Again, there’s a good chance that something will go wrong so act on your own volition.

The safest approach is to use a genuine Windows OS version.

With that said, we can conclude this article. In case you have additional questions, feel free to tell us in the comments section below.
