If i build a whole new computer and put my existing storage with windows 10 will my computer still have windows 10?
Assuming Windows 10:
Read and do this before you change any parts:

Thats for the licensing/activation.
For the actual operation...be prepared for a full reinstall.
There are 3 possible outcomes:
1. It boots up just fine
2. It fails completely
3. It boots up, but you have lingering issues
For a change like this, a clean install is highly
recommended, often
required.
