Fix DRIVER_VERIFIER_DMA_VIOLATION Error

The third time is charm saying goes but not when we are talking about Microsoft. Print spooler is again in focus, in a bad way. This is the third print spooler vulnerability to emerge in just five weeks. While a critical flaw was originally identified and patched in June, a similar flaw came to light shortly after and was subsequently patched (with mixed success). Microsoft is once again advising its customers to disable Windows print spooler after a new vulnerability that allows hackers to execute malicious code on machines has emerged. While a patch fixing the flaw will be released in due course, the most effective workaround currently on the table is to stop and disable the print spooler service entirely.

"An elevation of privilege vulnerability exists when the Windows Print Spooler service improperly performs privileged file operations. An attacker who successfully exploited this vulnerability could run arbitrary code with SYSTEM privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights."

Stop this service right away or you are risking a potential attack.

1. Press ⊞ WINDOWS + X to open the hidden menu
2. Click on Power Shell (admin)
3. In Power Shell type in the following command to check if spool service is running: Get-Service -Name Spooler followed by ENTER
4. If spooler service is running type in the next command to stop it: Stop-Service -Name Spooler –Force and press ENTER
5. Then follow with this command to disable it at startup: Set-Service -Name Spooler -StartupType Disabled followed with ENTER

That’s it, we hope a patch will come soon for all the people that are using network printing and indeed need this service running in order to do work.

• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net start cryptSvc net start bits net start msiserver

• After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
• Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.

• First, go to C:/Users/USERNAME/AppData and right-click on it then select Properties.
• Next, click on the Edit button in the Properties window and click OK to confirm if you got a User Account Control elevation request.
• After that, select user/group from the permission windows or click on the Add button to add another user or group. It would be best if you add “Everyone” to give permission.

Option 5 – Try to update Windows after a couple of minutes or an hour
