If these are legitimate programs there are two thing you can try:
1. Download the latest version of CCleaner (completely free and safe) and find the Tool option. Under Tool search for those programs and use the uninstall option. I and others have often found CCleaner's uninstall will often work better than Windows.
2. You could use the free RegCleaner utility that you can download from MajorGeeks.com. Keep in mind any time you go into the registery you need to be very careful. Caution is the first rule.
There is an Uninstall Menu tab. Click that on and search for ONLY those programs you want to uninstall. Leave the rest alone.
* Others with more experience may come along and give other solid advice based on experience as well.
