Get the Intel Serial IO driver
Intel Serial IO drivers run the I2C, SPI, UART and GPIO controllers that touchpads, touchscreens and sensors rely on. Most laptops get them from the PC maker's support page. Intel publishes Serial IO packages only for its own NUC products, run through SetupSerialIO.exe.

The short version
What to install and where it comes from. Every link goes to the manufacturer or Microsoft, never to a copy.
Official files only, nothing bundled
Step by step
Spot the symptom
Typical signs are a touchpad that only moves the pointer, a dead touchscreen, or devices called Intel Serial IO listed under Other devices or with a yellow mark.
Find your exact model
Open the PC maker's support page for your model. Look for Serial IO, Serial IO Driver or Intel Chipset in the lists.
Install chipset first
Install the maker's chipset package before Serial IO. This is the usual order on a fresh Windows install.
Install the Serial IO driver
Run the maker's installer. For an Intel NUC, Intel says to unzip the file and run SetupSerialIO.exe.
Restart and test
Restart, then check the touchpad, touchscreen and sensors. If the mark in Device Manager is gone, you are done.
What Serial IO is
Serial IO is a group of small controllers inside Intel’s chipset. They run slow buses: I2C, SPI, UART and GPIO. Few people notice them until something stops. A precision touchpad often sits on an I2C bus, and many touchscreens and sensors do too. When the Serial IO driver is missing, those devices go quiet while the rest of the laptop works.
Where the driver comes from
For a laptop, Intel’s pages are not the main source. The packages Intel lists are for its own NUC products, with pages such as the 11th Generation NUC and the NUC 9 Extreme laptop kit. One of them says the driver is needed if you use the GPIO or I2C host controllers. For any other PC, take the Serial IO driver from the PC maker, because it was built around that board’s wiring.
Install order
Chipset first, then Serial IO, then the device specific driver such as the touchpad. A fresh Windows install often misses one of these. If the touchpad still fails, go back to the maker’s list and look for a Human Interface or Touchpad driver. Intel Driver & Support Assistant can also scan an Intel system and offer updates for Intel parts it finds.
Questions
Can I install the NUC Serial IO driver on my laptop?
No. Intel's packages are listed for named NUC products. A laptop uses the version your laptop maker tested for its board.
Where do I see the controllers?
In Device Manager, expand System devices. The controllers show names such as Serial IO I2C Host Controller. In the PCI ID Repository the names include I2C, SPI, UART and GPIO.
Is this the same as the chipset driver?
No. The chipset package names the platform parts. Serial IO adds the working driver for the low speed buses.
My NUC is an older model.
Intel lists some NUC pages as moving to ASUS support. Check the NUC page and ASUS first.
