License issues preventing activation of Windows.
License issues preventing activation of Windows.
You've encountered an issue where your old Windows license isn't recognized after installing Windows Home on a new PC. It seems the system is rejecting the previous license, possibly due to licensing changes or account linkage problems. Check if your Microsoft account is properly linked and verify that the license is still active. If the problem persists, contact Microsoft support for further assistance.
Your previous license was likely OEM, and Microsoft doesn’t allow you to reuse them. There are several ways to obtain a new one: Purchase directly from Microsoft (not recommended), purchase an old desktop at a yard sale and install Windows 7 using the included key, or buy Windows keys from various gray-market sites for around $15 or less.
