Look for a way to upgrade my Windows xp computer to Windows 7

Download Windows 7 ISO and create a Windows 7 bootable USB for install. This is the standard procedure to upgrade windows xp to windows 7 nowadays. It is the simplest if it works for you, but it has a major limitation: it will only download the official ISO files from Microsoft's servers. If your product key is for an OEM version (e.g., from Dell, HP, etc.) or you already have an ISO, this tool may not accept your key or use your file.

Download the Tool: On a working Windows computer, go to the official Microsoft Windows 7 download page and get the "Windows 7 USB/DVD Download Tool".

Step 2 - Choose Media Type: Select "USB device".

Step 3 - Select USB Device: Insert your USB drive. The tool should detect it. Select it from the list and click "Begin copying".

Wait for Completion: The tool will format the drive and copy all the necessary files. When it says "Backup completed," your USB drive is ready.
