You need to format your 64bit windows and install 32bit on it. If you are having 64bit windows 7 and are planning to install 32bit windows by removing the 64bit then this article will help you transfer the Genuine windows activation key so that you can run Genuine windows 32bit using that key.
Nowadays all the laptops comes with Genuine 64bit windows. 64bit takes the full use of your RAM´s capabillities i.e. it can support more than 3Gb of RAM. But it can’t run the same programs as the 32-bit. Also different hardwares nowadays are still not compatible with 64bit windows i.e Wireless USB Modem.

To sill use the Genuine version of windows, there is a working technique of downgrading from 64bit of windows 7 to 32bit which is pretty straight forward but the process can be a little long.
First you need to have the exact same edition of Windows 7 32bit installation disk. After that backup the existing Windows 7 license to a USB flash drive. Reinstall Windows 7 32-bit and restore the OEM license.
Backup of license key can be done using a software called ABR (Activation Backup and Restore). The important rule is to make sure you restore the Windows 7 OEM activated license on the same edition of Windows 7. For example, if your laptop comes with Windows 7 Home Premium, you can only restore it back on Windows 7 Home Premium. If you try to restore a Home Premium license on a Windows 7 Ultimate operating system, the Status and Product ID will show “Not Available” in System. At desktop bottom right corner will also show the message “This copy of Windows is not genuine”.
Here is the exact steps of using ABR to backup and restore Windows 7 OEM license:
1. Download ABR Beta
2. Run ABRbeta.exe and it will extract the files to a new ABR folder.
3. Run activation_backup.exe from the ABR folder and it will create two new files backup-cert.xrm-ms and backup-key.txt in the ABR folder. Hit Enter to close ABR.
4. Backup the ABR folder by copying it to a USB flash drive.
5. Reinstall a clean version of Windows 7. During installation, leave the product key blank when asked to enter product key and uncheck the option where it will auto activate when your computer is online.
6. When Windows 7 has finished installing, plug in USB flash drive and run activation_restore.exe from the ABR folder.
7. Simultaneously press WIN+Pause/Break key to launch the System window. Scroll down and you should see “Windows is activated” with an OEM product ID.
