No, it isn't JRT. We both survived that. I've seen your problem mentioned elsewhere. It is a Dell thing that either...
(a) came with your computer (but you never saw it before), or
(b) downloaded from Drivers & Downloads (I think you said you did take something), or
(c) was brought in by Dell Update.
It might be the Dell Foundation Services - I have to go look. There's a thread somewhere about it. In the meantime...
(1) R-Clk START, & select "Programs & Features". Is there something from Dell recently installed...?...

(2) Examine your recent restore points...
(a) R-Clk START, & select "System".
The Control Panel opens at the System page.
(b) Click "Advanced system settings" at the left.
System Properties opens at the Advanced tab.
(c) Click the "System Protection" tab, to see...

If the Protection Setting for C: is "Off", you have no restore points. Click the Configure button to turn it on. Close out. Next time, you'll have them. If it was "On", continue.
(d) Click the "System Restore" button.
The System Restore requestor opens.
(e) Click "Next", & click into the "Show more restore points" box, to see...

(f) Select a restore point.
The "Scan for affected programs" button will activate. Click it to see what the restore point will undo. It will look like what I posted earlier.
**Just don't have it actually do the restore unless necessary.**But - to have it do the restore - you click "Next" on the System Restore requestor (under the "Scan for affected programs" button).
Probably, you just need to uninstall something to be cured of this problem. I'm going to look now.
