Accessing legacy systems on modern computers, phones, or tablets.
This article explores what PCjs is, how to use its Windows XP emulator, and why this browser-based approach to virtualization is revolutionizing the preservation of digital history. What is PCjs?
Windows XP has been out of extended support since 2014 and is riddled with unpatched security vulnerabilities. Running a physical or locally virtualized XP machine connected to the internet poses severe security risks. A PCjs instance, however, runs inside the browser’s security sandbox. If the virtual machine is compromised by legacy malware, the threat is contained entirely within the browser tab and vanishes the moment the tab is closed. The User Experience: What Works?

For more detailed information, the PCjs Project provides several resources:
Each has its unique strengths, but , as it actually emulates the underlying PC hardware rather than just recreating the visual interface. Accessing legacy systems on modern computers, phones, or
Load the HTML file in your browser. The boot will be slow (2–5 minutes). Once inside Windows XP, disable visual themes, animations, and unnecessary services to improve responsiveness.

Eliminates the need to download ISOs, allocate hard drive partitions, or install hypervisors.
There are several advantages to using PCJS to run Windows XP:
For a smooth XP experience, your virtual machine should mimic a high-end system from circa 2001-2002. Use these specifications as your baseline: : 80486 or Pentium (PCjs primarily uses the : 128MB to 256MB.
