I'm not a windows user for years, but some my relatives are.  I've been just pinged by them and asked to explain the new icon shown on their taskbar (because "you are a computer guy", you know)...   The icon:  The window:    My investigation resulted in:   It's in taskbar, not in notifications (i.e. closer to left). It disappears after reboot. It displays a small blank white window if clicked on. It looks like it does nothing.   My googling failed.   Can anybody tell me what is this? How to get rid of it?   Yep, that are crops from sorta screenshots taken with a phone sent via WhatsApp... Yep, that PC is running standard builtin windows antiviral tool... Yep, it's a mere desktop PC, not a notebook, with normal non-touchscreen display. And yes, this PC is not local to me and is operated by a non-tech person.

A spurious dialog box (informative, no?) keeps popping up on reboot.  What's an easy way to figure out what clearly-very-well-coded-piece-of-software threw it up there?  I've reduced the startup list to a minimal list to no avail.

Is there a complete list of these? I've seen lots of Q&amp;A about "What does x icon mean" but it would be really useful if there were a complete list for reference!

I'm concerned about an app on my child's phone. I saw an app icon in the notification area that looked strange (Andy Android head, slightly tilted as its icon).  How can I find out what app it is from just having seen that icon in the notification bar?

I've installed Taskbar eliminator, while it works most of the time, alerts being the taskbar back.  I've also installed object dock which can disable the taskbar, object dock appears during window changes.   Has anyone had any luck permanently removing, hiding the taskbar in Windows 7?  Update  I found an application that seems to be working here:    Second update  I took the leap and installed a shell replacement (). So far so good.

I have a program pinned to the taskbar. After I upgraded the program (I think) the icon broke. What I get now is what you see below; that ugly default application icon thing.    If I unpin it, I get the correct icon. If I then right-click on it, the icon breaks again. If I pin it again, still the broken icon. Unpin again and back to good icon. Very annoying. How can I fix this?

A few years ago Umber Ferrule wrote that the toolbars in the taskbar are defined in   HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Streams.   This looks very plausible but cannot be the entire story.  Deleting this key will in no way affect the taskbar and on rebooting the system the key magically reappears.  Why do I want to know?  Simple.  I would like to export the key to a reg. file as a convenient backup.

I am using Windows 7.  If I delete something from the desktop, then the icon remains there.  I have to hit F5 or right-click->Refresh to make the desktop refresh.  After the refresh, the icon disappears.  Any suggestions?

When moving/saving/etc a new file on the desktop, the icon appears second (just after "Computer"). I find it annoying, since I want my "special" icons to be first (such as the recycle bin, "Network", etc.).  Can this behavior be changed?

I'd like to change the icon of a app downloaded from the store. I googled it but just found out how to change basic icons like the desktop, bin, ...  Is it even possible to change windows-foreign icons?  At the image you can see which app I mean (ColorNote)

I have two screens on my Windows 8.1 computer (with Classic Shell Start Menu installed). The thing is that I would like to have the taskbar's  (where the clock and all the icons like Skype or Spotify are, at the right) on both of my screens, and not only on the primary one.  Could you help me ? I would like not to install a heavy and paid software like DisplayFusion.

Pressed the onscreen button on my s6 edge this afternoon and a strange new display swipe screen is showing up - picture included. I have no idea where this came from and I have to swipe it just to get to my pin lock. I've checked my apps, my settings, my locked screen, I've disabled some of the apps I thought it could've been but to no avail. Does this look familiar to anyone, and if so how do I get rid of it? It's eating up my battery life.

I was looking at the task manager in Windows 10 and for the first time noticed a secondary dashed line below the solid? What does this line indicate?

There is a yellow tooltip stuck and it floats above all other windows. I do not know from what program it came.  How can I get rid of it without restarting my computer?  EDIT:

When you open a tab on the , and switch to another tab, the icon has a partial white background: Firefox (Most obvious) - note the difference between that and the normal Stack Overflow logo  IE  Edge  Tested on Windows 10 with Firefox 41.0.2, Internet Explorer 11 and Microsoft Edge v20.10240.16384.0.

￼How do I get rid of this icon?  I'm not even sure what it's for. It's possible that it's for remote CD Drive, but I don't remember how I got it up there in the first place.  Details:   iMac 27 inch late 2012 OS X Mavericks
