Open Task Manager, click on the programs you want to open, click expand, then bring to front. If you can open Task Manager but it's running in the background, right click on the Task Manager icon in the systems tray, click always on top.
If that doesn't work, restore your PC to an earlier Systems Restore Point.
If that doesn't work, restart your computer, and boot into windows recovery and try to repair windows.
If that doesn't work, restart your computer, boot into safemode then see if it works, if it does, then you might have a virus that's hiding all your other programs. So go to Startup in Task Manager, while in safe mode and disable anything that you don't recognize (With caution of course, do a quick google search on your phone before you disable it, in case it's important.) then restart your computer and try again, if nothing still pops up. If that doesn't work, go onto another computer you have and download and install Avast Anti-Virus from here, after you install it, open avast, click Tools, then Rescue Disk from the drop down. Install the Rescue Disk on a USB drive, you will need to wipe it, and after you do that, plug the USB drive into your computer and while you are booting up your computer, go into the boot menu, and boot from the USB drive instead, it will boot Avast before your OS, and scan your whole PC for any viruses.
If that doesn't work. Your SOL.
