"before" pnputil /add-driver restore on Win10 LTSB 2016 from drivers exported from Win11 Enterprise LTSC 24H2
Win10 LTSB 2016 misses these drivers -
1) Human Interface Devices - HID Button over Interrupt Driver
2) Other devices - BT_FUNCTION
3) Other devices - Multimedia Controller
4 and 5) Other devices - PCI Data Acquisition and Signal Processing Controller
6 and 7) Other devices - PCI Device
8) Other devices - PCI Encryption/Decryption Controller
9) Other devices - SM Bus Controller
10 thru 18) Other devices - Unknown device
19) System devices - ACPI Wake Alarm
20) System devices - PCI Express Root Port
21) Universal Serial Bus controllers - UCSI USB Connector Manager
Task Manager = 28 processes, 328 threads, 10552 handles (after 49 minutes of Up Time due to a lunch break)
LTSB 2016 doesn't support DCH, so you'll have a hard time getting drivers for everything.
If you aren't noticing any obvious deficiencies though, chances are, those drivers aren't needed at all.
If you are having issues, I'd suggest trying LTSC 2019 or 2021, both of which have proper DCH support, and thus are much more compatible with drivers.
I'll mention which drivers are for what here:
1) Human Interface Devices - HID Button over Interrupt Driver
- This is most likely the power button. Ignore it if the button works fine.
2) Other devices - BT_FUNCTION
- Something related to bluetooth.
3) Other devices - Multimedia Controller
- Likely your speakers/line out port, if present. You should be able to find drivers for it quite easily. The drivers for most of these are the same as long as you get the right brand (eg: pick the closest available Realtek driver if it's a Realtek sound device).
4 and 5) Other devices - PCI Data Acquisition and Signal Processing Controller
- Probably TPM or fan control?
6 and 7) Other devices - PCI Device
- Probably Intel Management Engine or AMD Platform Security Processor. Likely unwanted.
8) Other devices - PCI Encryption/Decryption Controller
- Hardware encryption has been known to be unreliable, and software encryption is usually similar speeds these days (or sometimes even faster). If you aren't doing disk encryption, this likely doesn't affect you anyway.
9) Other devices - SM Bus Controller
- Likely Intel ME, AMD PSP, or fan control.
10 thru 18) Other devices - Unknown device
- Miscellaneous chipset things. Likely not needed.
19) System devices - ACPI Wake Alarm
- Used for scheduled wake from sleep or hibernate. Commonly used by Windows Update to power on or wake up the PC for updates. Not needed if you don't want that feature.
20) System devices - PCI Express Root Port
- Unknown. You'd need the driver for the port to be able to know what devices are downstream of it. Likely your chipset drivers will include this driver.
21) Universal Serial Bus controllers - UCSI USB Connector Manager
- Used for embedded systems functionality for USB-C ports. Likely not needed.
