"Windows Explorer stopped working"

Help needed, guys and gals!

Didn´t know to which category my issue belongs so I put it here. Mods, feel free to move.

Have had no crashes or other problems, have fallen in love with W7. But now there is a major problem. Until today I´ve been using my Logitech bluetooth KB & mouse (see specs) with W7 drivers without problems, but earlier today I got this stupid idea and installed Logitech Setpoint 4.72 to be able to use all the special functions and keys.

Like Setpoint installation told me, I turned Firewall and Defender off. Installation was OK, Setpoint connection helper found KB and mouse. And then came this:

I can start programs using Task Manager > File > New Task, but all Windows features are disabled (Win-key shortcuts etc.). My dual screen system looks now like this:

(To the left screen 1 = laptop, where you normally had all the icons, gadgets and taskbar)

Did a system restore, so Setpoint is no longer installed.

What now?

This was a weird issue. And I was stupid enough to make it even worse: to secure my files, I decided to make a full backup before making a system image recovery. And so I did. A full backup. And a system image backup, meaning my backup system image HAD THIS FAULT, too. So after doing a system recovery using my system image, I still had the same problem. How stupid am I?

But now everything is OK. I did a repair installation, and everything works.

Still very happy with W7!

...and learned something too!

Yes. But I still can not understand how my brain sometimes works: non-working system, so before I repair it using a system image (had one only couple of days old), I create a new one WITH THE FAULT, and then used that image.

When you think it, it´s really stupid.

Does that help, call yourself stupid?

You know, it's a bit surprising but sometimes it does help! This whole issue was my own fault (I call myself a professional! Hah!). With some low level brain usage this had never happened, that's why I called myself idiot, and it really helped.

Hello Jeddy and welcome to the SevenForums.

Like I told above, I fixed this issue with a repair installation. Here's Brinks excellent tutorial how to do that.

Repair installation is basically a modified in-place upgrade which repairs and reinstalls Windows system files leaving user files and installed applications intact.

You are welcome. Good luck.
