Hi,
I suppose the first thing you need to do is to find/specify a program you want to uninstall.
Please try this:
(1) [Control Panel] > [Programs] > [Programs and Features]
(2) Click on column header "Installed On" (i.e. sort by Installed date)
I hope you will find a program or two by installed date.
If you can find it, click it and [Uninstall]
Regards,
