Well I have a Lenovo K3 Note and would like to know if I could install windows on it if so could anyone tell me how because I've done my research and only ended up with tutorials and videos that use a software called change my software and while researching this software I came up with a few isuues some people say its malware and some say that its useless and will only brick my phone if you could provide me a method of installing windows on an Android phone and dual booting it with android I'd be greatful
In short: no.
I'm afraid there is little support in the area of custom flashing for your device as it is, even on the Android side.
This topic on XDA guides you to root the device and install a custom recovery but doesn't give any links ROMs, which you'd need. There is, however, a topic that allows you to install Cyanogenmod 12.1 (Android 5.1.1) here. Note that this is a not officially supported ROM and by the looks of the comments there appear to be quite some issues at the time being.
That doesn't mean all hope is lost. There are rumours by reputable resources that Microsoft is working on a way to install Windows 10 (partially) on an Android device but I wouldn't count on it arriving any time soon. Even if it is, there is no way of saying it'll be compatible with the K3 Note. The question is why you need this operating system. If it's specific Microsoft apps you're looking for, there's already a wide range of them available on Android (and iOS) such as Cortana (beta), Bing, Outlook or Word.
Virtualization can be a solution for you but you'll need a running Windows machine to connect your device to. Just Google for "run Windows programs on Android" and you'll find plenty easy-to-follow tutorials to get it done.
As for dualbooting, you'd be roaming dangerous territory. Dualbooting on an Android device is completely different from your average home PC dualbooting Windows and Ubuntu. There are tools like MultiROM, Safestrap, DualBoot Patcher and GRUB for Android but they are in most situations highly experimental.
I hope this helps you in the right direction and at least answers a part of your problem. Whatever you do, make a nandroid backup so if you get in trouble, you can still restore your original setup.
