SPAPI_E_SIGNATURE_OSATTRIBUTE_MISMATCH (0x800F0244) – Driver Won't Install? Here's Why

1. The catalog file is wrong for your Windows build

This is the number one reason I see this error. You're trying to install a driver that was signed against a different Windows version — say a Windows 10 driver on a Windows 11 machine, or a driver from an older build of Windows 10 on the latest update.

Last month I had a client whose Canon scanner driver threw 0x800F0244 on a fresh Windows 11 23H2 install. The driver's .cat file was built against Windows 10 20H2. It passed signature check but failed the OS attribute match.

The fix: Download the driver directly from the hardware manufacturer's site — not from a driver update tool. Those tools often grab generic signed packages. Look for the version that specifically lists your Windows build. If you can't find one, you've got two options:

1. Disable signature enforcement temporarily (not recommended for production machines). Boot into advanced startup, choose Troubleshoot > Advanced Options > Startup Settings, then press 7 to disable driver signature enforcement. Install the driver, then reboot normally.
2. Force the driver through pnputil. Extract the driver folder, open an admin command prompt, and run:

   pnputil /add-driver "C:\Path\To\Driver.inf" /install

   This sometimes bypasses the OS attribute check because it forces the install.

If neither works, you're likely stuck until the vendor updates the driver. Time to call their support.

2. Corrupted driver store or pending driver packages

Windows keeps a local store of signed driver packages at C:\Windows\System32\DriverStore\FileRepository. If a package gets corrupted or a previous install left a half-baked entry, the new driver can fail with 0x800F0244 because the OS can't validate the existing catalog.

I saw this on a Dell laptop where a printer driver had been partially uninstalled. Every subsequent install attempt threw this exact error. The printer manufacturer's uninstaller left orphaned files in the driver store.

How to clean it up:

• Open an admin command prompt and run:

  pnputil /enum-drivers

  Look for the driver that's causing the trouble. It'll have a oemN.inf name. Note the Driver name next to it.
• Remove the old package:

  pnputil /delete-driver oemN.inf /uninstall

  Replace oemN.inf with the actual number.
• Now try installing your new driver again.

If you don't know which driver to delete, use the Device Manager trick: find the device, open Properties, go to the Driver tab, click Driver Details, and look for the .inf file path. That tells you which oemN.inf to target.

3. Windows update or feature update broke the signature validation

Sometimes the error appears after a feature update — like going from Windows 10 21H2 to 22H2. The update changes how Windows validates driver catalog attributes, and existing drivers in the store suddenly fail the check.

Had a client whose network card driver (Realtek) worked fine for months. After the 22H2 update, it threw 0x800F0244 on every new install. The driver itself hadn't changed — Windows did.

The fix that usually works:

1. Download the latest driver from the chipset vendor. Realtek, Intel, and Broadcom usually update their packages within a month of a feature update.
2. If that's not available, roll back the feature update temporarily. Go to Settings > Windows Update > Update History > Uninstall updates. Remove the latest feature update. Install the driver, then block the update using the Show or Hide Updates troubleshooter from Microsoft.
3. As a last resort, disable driver integrity checking on the device:

   bcdedit /set testsigning on

   Reboot and install. Only do this on test machines — it leaves your system open to unsigned drivers.
