How to Fix ERROR_POINT_NOT_FOUND (0X00000493) on Windows

Why You're Seeing This Error

I had a client last month whose entire system would freeze for two seconds every time they moved the mouse in AutoCAD. Event Viewer kept throwing 0x00000493. That's the ERROR_POINT_NOT_FOUND code—Windows can't find the next mouse position in its internal buffer. It's not a virus. It's not corrupt Windows files. It's almost always one of three things: bad drivers, a USB power saving setting, or a third-party app hijacking the mouse stream.

Here's the order to attack it. Start here.

1. Update or Roll Back Your Mouse Driver

Nine times out of ten, the driver is the culprit. Either it's ancient and doesn't handle the high polling rate of your gaming mouse, or a Windows update pushed a generic driver that doesn't match your hardware.

What to do:

• Open Device Manager (Win+X > Device Manager).
• Expand Mice and other pointing devices.
• Right-click your mouse and select Update driver > Browse my computer > Let me pick from a list.
• Try the HID-compliant mouse option if you see it. If you have a Logitech or Razer, pick the OEM driver from the list.
• If that doesn't help, go back to the driver tab and select Roll Back Driver—especially if the error started after a Windows update.

I fixed a Dell laptop last week doing exactly this. The user had a wired USB mouse that worked fine until a November 2023 patch. Rolled back to the 2022 driver, error gone.

2. Disable USB Selective Suspend

Windows loves to save power by turning off USB ports when it thinks they're idle. But if you're using a high-DPI mouse or a laptop with a touchpad that uses the same internal USB hub, the port can get suspended mid-move. That's when the buffer empties and you get 0x00000493.

How to kill it:

1. Open Control Panel > Power Options.
2. Click Change plan settings next to your active plan.
3. Click Change advanced power settings.
4. Find USB settings > USB selective suspend setting.
5. Set it to Disabled for both battery and plugged in.
6. Apply and reboot.

This is also the fix if your mouse randomly stops moving for half a second while you're typing. It's the USB controller going to sleep and waking up too slow.

3. Run a Clean Boot to Find the Conflicting App

Sometimes it's not the driver or power settings. It's a piece of software that hooks into mouse movement—things like AutoHotkey, X-Mouse Button Control, display fusion, or even older RGB lighting software. They intercept the mouse point buffer and don't return it fast enough.

Steps:

1. Press Win+R, type msconfig, hit Enter.
2. Go to the Services tab, check Hide all Microsoft services, then click Disable all.
3. Go to Startup tab, click Open Task Manager, and disable everything there.
4. Restart. Test your mouse. If the error is gone, start re-enabling services and startup items in batches until it comes back.

A real-world example: a designer I know had this error every time he opened Adobe Illustrator. Turned out one of his old Wacom tablet drivers was fighting with the mouse driver for the buffer. Uninstalled the Wacom driver completely, error gone.
