VLC always crashes when started

Quit VLC, go to Regedit (Win+R regedit) and delete the key HKEY_LOCAL_MACHINE/SOFTWARE/VideoLAN.

This deletes the previous configuration settings which can have leftover settings which the new VLC cannot handle.

How to disable automatic spell checking in Skype

A reddit user provides the answer:

 there is a workaround for any Windows. Go to:

%userprofile%\appdata\roaming\microsoft\skype for desktop\dictionaries

Exit Skype, delete "en-US.bdic" (or whatever the name of the one you see there is), and then create a new dummy file by that name (you can right-click in Explorer, select New, and then choose Text Document--but be sure to rename it to the exact name, including extension).

Now right-click it, Properties, Security, Advanced. Disable Inheritance/Remove all inherited permissions from this object. Apply. Then OK out.

Now start Skype again and it will not be able to recreate the real dictionary file, as it otherwise would have done, and there will be no spellchecking.

All of the above, may need to be redone each time Skype upgrades.

Deleting undeletable Android apps without rooting the phone

It is possible according to this post. The solution is quite technical, though. I haven't tried it, but you'll have to start looking up what adb is, how to run it, etc. if you want to give it a try.  I just noted it down here, in case it's needed sometime.

Wireless mouse suddenly starts moving on its own

I have a Windows 8.1 laptop, but at home I use it with an external monitor and wireless keyboard and mouse. One day I got home and plugged the usb receiver of the keyboard and mouse into the laptop and started using it.

But anytime I used the mouse the cursor started moving left on its own. Very annoying. After digging a bit and trying solutions which recommended upgrading driver software and such which did not help, an article mentioned interference.

And lo and behold, some cables got twisted, got near the usb receiver and when I straightened them and moved them away from the usb receiver of the mouse, the problem went away.

So look out for interference from some cables if you use a wireless mouse and/or keyboard.
