How to Reverse the mouse scroll direction in windows
TL;DR – Run regedit as an admin, search for “FlipFlopWheel” and replace the 0’s with 1’s, unplug and reinsert the mouse.
- Open Control Panel, double click “Mouse” to open the mouse properties windows, and then click on the “Hardware” tab.
- Select your mouse in the list of devices then click on the properties button in the bottom right corner, just above the “Apply” and “Help” buttons.
- In the device properties dialogue window, click on the “Details” tab and then select “Hardwire Ids” from the “Property” drop-down list. You should see a list of entries starting with “HID…”. Write down the values that start with “HIDVID_???…”.
- Close device properties by clicking “Cancel”.
- Close “Mouse Properties” by clicking “Cancel”.
- Find and open the application “regedt32.exe” as an administrator, if you are not already logged in as one.
- Navigate to “HKEY_LOCAL_MACHINESYSTEMCurrentControlSetEnumHID”, and look for an entry that resembles the “VID_???…” number that you wrote down earlier in step 3.
- Open each sub entry under your specified “VID_???…” key, and open the “Device Parameters” key.
- There should be a key named “FlipFlopWheel” under each of the “Device Parameters” key. Reverse the entry value for the “FlipFlopWheel”. i.e. if default is “0” (zero) change it to “1”, and vice-versa.
- Do the same step 9, for each alphanumeric text string key entry, and their “Device Parameters”, “FlipFlopWheel”.
- Close “regedt32.exe”.
- Unplug your USB mouse, wait for 5 to 10 seconds, then plug the mouse back in again. If that doesn’t work then reboot.
