### Remove unsigned drivers
### Repair unsigned drivers
Drivers that are not properly signed can block the upgrade process. To check your system for unsigned drivers:
Drivers that are not properly signed can block the upgrade process. Drivers might not be properly signed if you:
- Disabled driver signature verification (highly not recommended).
- A catalog file used to sign a driver is corrupt or missing.
Catalog files are used to sign drivers. If a catalog file is corrupt or missing, the driver will appear to be unsigned, even though it should be signed. This can cause the upgrade process to fail. To restore the catalog file, reinstall the driver or copy the catalog file from another device. You might need to analyze another device to determine the catalog file that is associated with the unsigned driver. All drivers should be signed to ensure the upgrade process works.
To check your system for unsigned drivers:
1. Click **Start**.
2. Type **command**.

7. After the scanning process is complete, click **Advanced**, and then click **View Log**.
8. Locate drivers in the log file that are unsigned and remove or update them using Device Manager. For more information, see [Using Device Manager to uninstall devices and driver packages](https://docs.microsoft.com/windows-hardware/drivers/install/using-device-manager-to-uninstall-devices-and-driver-packages).
7. After the scanning process is complete, if you see **Your files have been scanned and verified as digitally signed** then you have no unsigned drivers. Otherwise, you will see **The following files have not been digitally signed** and a list will be provided with name, location, and version of all unsigned drivers.
8. To view and save a log file, click **Advanced**, and then click **View Log**. Save the log file if desired.
9. Locate drivers in the log file that are unsigned, write down the location and file names. Also write down the catalog that is associated to the driver if it is provided. If the name of a catalog file is not provided you might need to analyze another device that has the same driver with sigverif and sigcheck (described below).
10. Download [sigcheck.zip](https://download.sysinternals.com/files/Sigcheck.zip) and extract the tool to a directory on your computer, for example: **C:\sigcheck**.
>[!NOTE]
>If a file is corrupted, it might display as unsigned. Be sure to [repair the system drive](#repair-the-system-drive) and [repair system files](#repair-system-files) before attempting to replace unsigned drivers.
#### Optional: Use sigcheck
[Sigcheck](https://docs.microsoft.com/sysinternals/downloads/sigcheck) is a tool that you can download and use to review digital signature details of a file.
To use sigcheck:
1. Download [sigcheck.zip](https://download.sysinternals.com/files/Sigcheck.zip) and extract the tool to a directory on your computer, for example: **C:\sigcheck**.
2. Click **Start**.
2. Type **command**.
3. Right-click **Command Prompt** and then left-click **Run as administrator**.
4. If you are prompted by UAC, click **Yes**.
5. In the command window, use the **cd** command to switch to the directory where you extracted sigcheck, for example **cd c:\sigcheck**.
6. A list of drivers with their path is displayed in the File Signature Verification tool (step #7 in the previous procedure). Optionally, you can generate a list of drivers using driverquery.exe. To use driverquery, type **driverquery /v > c:\sigcheck\drivers.txt** and press ENTER. See the following example:
```cmd
C:\Sigcheck>Driverquery /v > C:\sigcheck\drivers.txt
[Sigcheck](https://docs.microsoft.com/sysinternals/downloads/sigcheck) is a tool that you can download and use to review digital signature details of a file. To use sigcheck:
11. In the command window, use the **cd** command to switch to the directory where you extracted sigcheck, for example **cd c:\sigcheck**.
12. Using the list of unsigned drivers and their associated paths that you obtained from the File Signature Verification tool, run sigcheck to obtain details about the driver, including the catalog file used for signing. Type **sigcheck64 -u -e \<driver path\>** and press ENTER. See the following example:
```
7. Open the drivers.txt file and locate the problem driver that was reported by sigverif in the [procedure above](#remove-unsigned-drivers). Copy the path to the driver.
8. To check the driver, type **sigcheck64 -u -e \<driver path\>** and press ENTER. See the following example:
```
C:\Sigcheck>sigcheck64.exe -i c:\windows\system32\DolbyMATEnc.dll

In addition to unsigned drivers, drivers might be signed with an invalid certificate, requiring the driver to be updated or removed so that Windows upgrade can continue. Sigcheck will report whether or not the certificate chain is valid.
13. Optionally, you can generate a list of drivers using driverquery.exe, which is included with Windows. To save a list of signed and unsigned drivers with driverquery, type **driverquery /si > c:\drivers.txt** and press ENTER. See the following example:
```cmd
C:\>Driverquery /si

To resolve a rollback that was caused by driver conflicts, try running setup using a minimal set of drivers and startup programs by performing a [clean boot](https://support.microsoft.com/kb/929135) before initiating the upgrade process.
