Step 1: Open Registry Editor with Windows + R and type "regedit"

Step: 2: navigate the folders to reach this point: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class

Step 3: Under the Class folder, you'll find a long list of keys. If you're issue is like mine and is related to only the touchpad, find and open 4D36E96F-E325-11CE-BFC1-08002BE10318 (take your time, make sure you don't modify the wrong folder)

Step 4: If you see the file "Upperfilters", delete it.

Step 5: Right click, select "new", select "New Multi-String Value" and name it "Upperfilters". You're essentially remaking the file you just deleted.

Step 6: Double click on the new "Upperfilters" value you just made. In the "Value Data" box, type "mouclass" and save. You might have a pop-up say something along the lines of "we can't register blank lines" but you can just ignore it. I don't know if the system is cap sensitive, but just in case I used the exact capitalization used in the reddit post. Capital U for Upperfilters, and all low caps for mouclass.

You should now have a replacement file with the following information:
Name: Upperfilters Type: REG_MULTI_SZ Data: mouclass

Now restart your computer, if it worked, nothing should be broken and your touchpad issues should be fixed!

Hi AdrianG001

Thank you for your reply.

When I looked under the Class Folder:- "4D36E96F-E325-11CE-BFC1-08002BE10318" in the Windows 11 Registry the file: Upperfilters was showing as (UpperFilters).

Sadly the above suggestion did not solve the problem with the Synaptics Error Message and the problem still occurred when I rolled back the Operating System on the Laptop to Windows 10 via a Factory Reset.

For a brand-new system, I know this is quite unexpected. I apologize for the trouble. Don’t worry, we are confident that the seller should help you sort this out, have you contacted them yet?
