        My new monitor is 2560 x 1440 and for productivity reasons I like to be able to move my mouse cursor fully from side to side and top to bottom of the screen primarily with finger and wrist movement only. So my mouse cursor speed/sensitivity is set to maximum. The trade-off is it makes it harder to land the pointer accurately on extremely small target areas of the screen. For me, the only time this trade-off is too high is when trying to land on the very narrow edges of desktop windows so I can resize them on the fly. I’ve been living with this for months and finally got frustrated enough to take action.

        I couldn’t find any settings in “Windows Settings” or in Control Panel to change the width of the zones for grabbing the edges or corners. Let me know if I’m missing some setting somewhere!

        Searching the web was mostly a dead end until I found the following registry edit:

        HKEY_CURRENT_USERControl PanelDesktopWindowMetrics
        Double click on BorderWidth. (Mine was set at “-15” which I think ends up being only 1 or 2 pixels wide?)
        Change it to a larger negative number, close regedit and restart the computer to apply the change.

        After some testing, I settled on “-160”. The fiddle-factor to grab a window edge has been resolved. And, no, it didn’t change the visual thickness of the windows borders – only the width of the drag zones.

        I don’t know how to change the size of the resize handle (well, I do now after reading the post), but perhaps the mouse can be made more friendly. Did you check the box for “enhance pointer precision” in the old, Control Panel settings? That introduces negative pointer acceleration at low speeds, so when you are moving the mouse slowly, it reduces the mouse movement speed to less than the nominal speed (as far as I can tell).

        I always used this setting in Windows… tick that first, then set the pointer speed. It makes hitting narrow elements with the mouse far easier when I have a relatively high speed setting, as I do. I like the mouse (an actual mouse, not a touchpad) to move about 3/4 of an inch (19mm) to an inch (25mm) go from the left edge of the screen to the right at low speed. At high speed, it accelerates to about half that.

        It’s equally important for touchpads, IMO. I always checked the box for those too.

        Incidentally, it is the lack of a setting like this that makes me dislike the libinput driver in Linux for touchpads. I use synaptics instead to get this functionality back.

        Edit: I just caught the bit about the cat with tortitude! I have one of those too. She’s a torbie, or perhaps a tabico. She has black, gray, cream, orange, brown stripes on her body and white belly, bib, and paws. Conflicted whether that makes her a tabby+tortie (white belly and bib are a normal color variation of tabby) or a tabico (tabby calico). Love her to pieces either way!

          Thanks. I now remember trying that feature early in Win 7. My muscle memory didn’t care for the feeling of ‘deceleration’ as I slowed the cursor when getting close to target or moving the pointer shorter distances. It’s a sort of ‘moving-in-honey’ feel.  I just now tried it in Win 10 and it still feels weird, though it does make the mouse more precise with small movements. I’ll take a few days to see how and if my habits adapt. 🙂

          I’ve had three tortoise shell cats in succession. All were quite intelligent, eccentric, sometimes demanding yet always engaged companions and ‘playmates’. Our second cat lived to the ripe age of 20 years. She spent those years living with us on our sailboat and sailed with us wherever we went, including from Seattle to Alaska and offshore down to Mexico. Quite the seafarer! Our current tortie, CoCo, has also sailed with us in Mexico. She immediately took to the boat like it was a big Jungle-Jim. She is trained to a harness and wore a life-vest on our passages.. lol!

        Steve, thanks for this. It works for this old guy!

        Unless you're in a hurry, just wait.

        Excellent tweak. I remember using it long ago but couldn’t remember or find it again until finally stumbling into this place.

        Absolutely necessary on 4K monitors. Windoz should just provide a slider in Display settings for this adjustment.
