Advancing Windows driver security: Removing trust for the cross-signed driver program
Microsoft announces the removal of trust for all kernel drivers signed by the deprecated cross-signed root program, enhancing Windows security by enforcing that only drivers signed through the Windows Hardware Compatibility Program (WHCP) are trusted by default. This change will take effect with the April 2026 Windows update for Windows 11 versions 24H2, 25H2, 26H1, and Windows Server 2025, aiming to reduce attack surfaces while maintaining compatibility for essential cross-signed drivers through an allow list.
Microsoft Print to PDF not working/missing.
The Microsoft Print to PDF was not working on my PC so I tried reenabling it via Windows Features in Optional Features and it won't turn back on. It gives error code: 0x800f0922. I also tried other various methods online and none work. All end with various error codes which all result in the service not working/turning on. I even filed feedback about 2 weeks ago with no response yet. I contacted support, where I was recommended to perform a repair via ISO but was then canceled by the agent as I am on an Insider build. I am on build 26300.8687. This is a summary of my diagnostic from Gemini which I had used to try to solve my issue. Here is a summary of the diagnostic, tracking every command I executed in PowerShell and the specific roadblocks the Windows subsystem threw back. The Add-Printer Layer attempted to use modern PowerShell commands to register the printer onto both the interactive prompt port and the standard local file port. Commands Ran: PowerShell Add-Printer -Name "Microsoft Print to PDF" -DriverName "Microsoft Print to PDF" -PortName "PORTPROMPT:" Add-Printer -Name "Microsoft Print to PDF" -DriverName "Microsoft Print to PDF" -PortName "FILE:" * **Errors Faced:** * `ObjectNotFound: (MSFT_Printer:ROOT/StandardCimv2/MSFT_Printer)` * `HRESULT 0x80070002,Add-Printer` --- ## 2. The Legacy PrintUI Layer To bypass the modern PowerShell cmdlet, I tried using the legacy Windows user interface print engine via standard command prompt syntax and escaped quotes. * **Commands Ran:** ```powershell cmd /c "rundll32 printui.dll,PrintUIEntry /if /b `"Microsoft Print to PDF`" /r `"PORTPROMPT:`" /m `"Microsoft Print to PDF`"" rundll32 printui.dll,PrintUIEntry /if /b "Microsoft Print to PDF" /f "C:\Windows\System32\spool\DRIVERS\x64\3\prnms009.inf" /r "PORTPROMPT:" /m "Microsoft Print to PDF" Errors Faced: A graphical dialog box error: Operation could not be completed (error 0x00000002). The system cannot find the file specified. The Deployment Script Layer (WMI/CScript) I tried deploying the printer using Windows’ built-in visual basic administrative scripts to side-step the user interface layer completely. Command Ran: PowerShell cscript $env:windir\System32\Printing_Admin_Scripts\en-US\prnmngr.vbs -a -p "Microsoft Print to PDF" -m "Microsoft Print to PDF" -r "PORTPROMPT:" * **Errors Faced:** * `Unable to add printer Microsoft Print to PDF Error 0x80041002 Not found` * `Operation PutInstance` * `Provider Win32 Provider` * `Description The system cannot find the file specified. Win32 error code 2` Ultimately, every single command failed with an identical variation of **"File Not Found" (Error 2 / 0x80070002 / 0x80041002)**.Pascal (10 series) GPUs on Windows 11 encounter artifacting boot loop when HDR is enabled in Windows
