Don't let Microsoft Update or Windows Update install the Ideacom Technology - Input - HID Touch Screen (PS/2) driver on your PC. If you do, it will replace your mouse driver and your mouse will not work.
This update is offered as Optional but there is no indication of what it will do to a PC that doesn't have a touch screen that uses this driver. To avoid seeing it in the future, right-click on the update and choose "Hide Update".
If you have installed this update and your system is hosed then bad luck. You will need to find out how to drive Windows without a mouse. Try the following keystrokes to get you to Driver Manager:
Ctrl+Esc: Same as clicking the Windows Start button (bottom left corner of your screen)
Alt+Tab: this will let you choose which window or application you want to control from the keyboard
Tab: this will let you choose which button or input field you want to control
Enter: this will click the default button
Space: this will select and deselect a check box
Alt+letter: this will click the button which has 'letter' underlined. i.e. If you press Alt and you see an underscore under the letter N on the button you want to press, then press N while keeping the Alt key pressed.
Use these keystrokes to uninstall the touchscreen driver. If you are offered the chance to delete the driver then accept it gratefully.
Good luck.
p.s. The name of this post comes from a popular saying about Disney Corp. I can't find any attribution for this phrase and it's not as common on Google as I would have guessed. Any idea who first said it?
Years ago, when Classic FM was first starting up, they did some test transmissions on the new frequency. I happened to tune in one day while driving. The test transmission was simply a recording of birdsong in woodland. Wow. I didn't listen to another radio station in my car until the proper Classic FM programming started. Obviously I tuned away pretty darn quick at that point. Henry Kelly. Enough said.
Fiddling with a DAB radio at home yesterday I happened upon a digital station called Birdsong. Yay! It's the same recording I think. I cannot recommend this station highly enough. It's incredibly calming to hear the sounds of the countryside when you're sitting in an office surrounded by technology.
Do try it.
