My computer cursor won’t click on anything but it moves just fine , this is a windows ten I bought three years ago by the way. Anyone know why?

How it's going to be my mouse that was brand new, never dropped, never damaged, only placed over a top-quality mat. people with brand new machines, straight out of the box already got this issue. and you are referring to a Logitech mouse. i do not own Logitech peripherals. it's more of a Build issue. i remember a couple months ago (it literally went away after this) i smashed this god damn thing against my desk and that fixed it for me. it came back again today...

there are some people out there who has this problem related to Logitech software and their fix is to delete it. but for people like me who uses no gaming software or have another brand of mice, like razer or SteelSeries for example this fix it's useless sadly, still thank you for doing a better troubleshooting than literally Microsoft employees.

I came to this thread in hopes of finding the solution. Instead, I figured out my (mom's) problem, and thought I'd share in case it helps others. So...it's your mouse. I know, I know. "How can it be my mouse if my touchpad/other mouse doesn't work?" Well, I'll tell you my story, and you can decide.

Mum was using her work laptop (Lenovo Thinkpad) with her own mouse, a Logi M720...and she spilled coffee on the mouse. It didn't die immediately, but at a certain point hours later and after she switched to her personal laptop (a "consumer grade" Lenovo), she began to have the problem everyone here describes: Mouse will move the pointer, but you can't click anything. Indeed, even when she switched off the Logi mouse, both her backup corded mouse and the "clickpad" exhibited the same behaviours: Pointer yes, clicky no.

She had already tried restarting, as well as changing the channel of the mouse-computer Bluetooth connection, which didn't help. I initially tried the Ctrl+Alt+Del trick, which didn't work for long at all. At a certain point, though, I did Ctrl+Alt+Del while the Logi was switched off, and voilà! The corded mouse and touchpad started working again. I tried fixing the mouse with penetrating lube (e.g. WD-40), which I thought had fixed it, but it stopped working as I was typing this comment (I'll need something better at displacing water...maybe 99% iso). Even so, the click on the corded mouse and clickpad both work properly.

So, in short:

1. turn off your suspect mouse by the switch (if cordless) or unplug it,
2. (if it's Bluetooth and you don't use a dongle) go into Bluetooth devices and "Remove device", and
3. then do Ctrl+Alt+Del

and see if that sets you right. If your "mouse" is in fact a laptop's clickpad (touchpad), you'll need an external mouse of some kind to test this. This was easier on mum's home computer because it's touchscreen (never thought I'd be happy about it), but I assume you can do the same with Windows key, arrow keys and Ctrl+Alt+Del. Hope this helps.

Still sounds like it might be the same problem. If you're using a desktop, try with a different mouse (and bring up Task Manager with CTRL+ALT+DEL). If it's a laptop, same steps, but first go into your settings to turn off your touchpad. If you get into a situation where both mouse and touchpad don't work, you can navigate with TAB and ALT, and/or use the Windows key and type things into the search.

For me I can use my mouse fine on browsers, taskbar, and windows start shortcuts, but I cannot click, open, or highlight anything on the desktop itself.

I had this problem then I realised that a button on my mouse had gotten stuck (I use a gaming mouse so it had a button on the side that had gotten stuck) and just needed fixing so before trying other solutions make sure to check all the buttons on your mouse to make sure they are not stuck or being held down

The problem is that a button is stuck on your mouse or touchpad (clickpad). After a while of it being stuck, the computer acts like you want it stuck on, and keeps it that way even if you unplug the mouse or turn off the clickpad. Opening Task Manager resets this, but only after you've disconnected the malfunctionong hardware.

If you're using an external mouse:

1. turn off your suspect mouse by the switch (cordless) or unplug it (corded),
2. (if connected by Bluetooth) go into Bluetooth devices and "Remove device", and
3. do Ctrl+Alt+Del, and then click "Task Manager" (you don't have to change anything in Task Manager, so just close it)
4. Use a different mouse, or on a laptop, use the clickpad

If you're using a laptop clickpad, you either have to get your existing clickpad's left-click or right-click unstuck, or you have to replace it. If you can't do either, opening task manager may fix it very temporarily if the button is unstuck at that moment, but you'll likely encounter the same problem as soon as you try to click it. I've noticed this problem on laptops where there's almost no gap between the clickpad and the chassis of the laptop. The best solution long-term for people with a stuck clickpad will be to switch to an external mouse, if possible.

Hope this helps.
