Windows 10 served us well, but Microsoft recently decided that its time has come to an end. With the discontinuation of security updates, many people are finally making the dreaded upgrade to Windows 11.

Jumping from Windows 11 Home to a Pro license supercharges Windows—useful if you need more advanced features. If you’ve been considering the leap, there’s good news for the holidays. Right now a Windows 11 Pro upgrade license is just $48 through PCWorld’s own software store or 52 percent off the normal price.

Microsoft’s minimum requirements for Windows 11 cover several hardware components, including having enough RAM and a powerful enough microprocessor. But the most contentious issue is whether a PC contains or supports a Trusted Platform Module (TPM), specifically version 2.0, released in 2014.

TL;DR: It’s only $17.97 to upgrade to Windows 11 Pro, but this sale ends December 22. As support for Windows 10 winds down, it’s really important to upgrade to an operating system that keeps pace with modern demands.
