Hello cakky,
You dont actually need to uninstall WAMPServer.
You can instead just remove the 2 services Apache and MySQL that it installs.
Do this to remove services
left click wampmanager icon -> MySQL -> Service -> Remove Service
left click wampmanager icon -> Apache -> Service -> Remove Service
Leave the wamp folder where it is its just data now
When you want to use wamp again do the reverse
left click wampmanager icon -> MySQL -> Service -> Install Service
left click wampmanager icon -> Apache -> Service -> Install Service
Also if you need a different version of PHP WAMP allows you to have an unlimited number of versions of Apache/MySQL/PHP installed. You then just switch between the versions you want to use for a specific project.
Try
left click wampmanager icon -> PHP -> Version - Get more
This should throw you to the WAMPServer website where you can download various versions of PHP from the ADDONS links on the page.
If they dont have the version you want, you can also do this process manually if you feel up to it. If you want to try this I can send you a HowTO install PHP versions manually tutorial I wrote.
Not all PHP's run with all Apache'2 so depending on what you are currently running and what you want to run you may also have to download andother version of Apache, also available using the 'Get more' link under the Apache menu. And again if the version you want is not there I can send yo a HOWTO on installing Apache into wamp manually as well.
