Start with a repeatable observation
A file selection ending early and an uncomfortable long mouse hold are different problems. Before adding a workaround, repeat the same drag with lock features disabled. Keep the pointer inside the testing area, note any release you did not intend, and repeat in a second application. A result that changes between applications deserves investigation before a hardware verdict.
The KBT drag page exposes browser-delivered pointer behavior. A double-click check adds a different observation: whether one intended press is followed by unexpected repeated clicks. Neither test can read the physical switch directly. Connection, software and input-routing differences still matter.
Change one setting, then repeat
PowerToys 0.102, released October 21, 2026, adds Mouse Button Lock. After enabling a button, hold it stationary for the configured duration, release your finger and continue the drag. A subsequent mouse-button press releases the logical hold.
The default hold is 1,200 ms, adjustable from 200 to 2,200 ms. The default movement threshold is 5 px, adjustable from 0 to 100 px. Movement beyond the threshold during the activation hold cancels that activation. Right-button locking is selected by default once the utility is enabled; left-button locking is off. Windows ClickLock is the existing left-button alternative.
Repeat the original task with the new setting. Record whether the convenience feature engages when expected and whether an ordinary drag remains ordinary. Avoid changing connection, application and activation duration simultaneously: that makes a comparison difficult to interpret.
Preserve the boundary
Raw or exclusive-input games may not honor the utility, and elevated windows introduce a privilege boundary. A browser demonstration is not a guarantee about either environment. CursorHide is a separate visibility feature: it can hide the pointer during typing, and is not a repair for a mouse that produces unwanted events.
Read the full PowerToys guide or try the mouse drag test. Browser tests observe delivered input events and cannot certify a physical switch, driver or every application.
