I wouldn't risk using a cracked version of Windows as my operating system for my bitcoin wallet knowing that nobody knows how many backdoors are installed in such operating systems and the mere fact that it's easy to mask some things as normal Windows processes nowadays and Defender wouldn't be able to distinguish it right away.

Don't cheap out on your operating system. They come in cheap at eBay now and retails for about $10 - $50 depending on what version of Windows plus the nature of the product key that you'll be buying.


Removing it isn't always enough. Buy a legitimate copy of Windows and do a fresh install on your hardware. This will settle things out and ensure that no leftover software junk resides on your C:\ drive.
