- You can reactivate your Windows Vista installation by performing the following:
1. Click on the Start button and in the Start Search box type in: slui.exe 3 and click on the icon that appears.
2. Type in your Windows Vista 25-character product key.
3. Follow the instructions for phone activation (no charge).

Can you confirm if you have made any hardware change. Also can you tell us the license channle for your Windows. Was it an OEM installation[came installed from vendor], Retail[You brought the Disk and a key from Microsoft] or Volume License[You are an Enterprise user].
Environment 1 : If you have done any hardware change and it was an OEM installation than you cannot use your key again however you can try following Step 1 however if you have not done any hardware change then you try step 2.
Environment 2:
If it was a Retail installation and there were hardware changes then you can try Step 3 and if you have not done any hardware change then you can try Step 4.
Environment 3: If it was an installation from a VL agrement then for sure you have a MAK key installed and that has excceded the limit. You can then follow the step 5
