Urgent Please:Windows cannot load the device driver for hardware.

Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)

Windows Critical update and now sadly I have all USB drivers with yellow triangle type sign..tried uninstalling drivers etc..still the same. Search web but found nothing that I can handle ..anyone help please..I have 3 USB drives I cannot use..I se them in device manger etc but nothing I can do to them.. I see only my c: drive and my cd/dvd drive indicated as good. I updated USB drivers and am desperate for help..My backups etc are on the USB drives..restore does not see m to work. I read about filters and conflicts..can anyone guide me here..

Have you tried a system restore to a restore point before this happened?

pbcopter: yes I did from 4 points and it will not restore correctly.. I tried a reg merge from a full reg backup and it would not merge correctly.. I was hoping that would help... I have ERUNT one on the other drives...smile..I have all sort as it were..but..but nothing that will help me..it seems it may be a permissions thing wrapped up in a upper and lower filter issues..out of my league but I can follow instructions.

When did this happen?

Can you tell us a little more of when it happened?
Were you upgrading windows? Just happened? etc. more information will allow us to better point u in a direction to follow

I don't see the Device Manager screenshot, the most important one.

We need the Driver tab from each device in error as well.

Meanwhile try installing the drivers from an Admin account.

You may have messed up the registry with the attempted reg merge which is more advanced than any normal user should try. Run SFC -SCANNOW Command if necessary from DVD Repair console or Repair CD command prompt so it doesn't depend on possibly corrupt System Files: SFC -SCANNOW Run in Command Prompt at Boot

If this fails, consider a Repair Install

Take a screenshot of the Device Manager with any devices in error expanded so we can see their listings.

Use Snipping Tool in Start Menu, attach using paper clip in reply box.

Then click on the erroring Devices to take a screenshot of the Properties box with Driver tab showing for each.

If you have Problems running System File Checker, boot the DVD or Repair CD, press Shift + F10 to open a Command Prompt, then run SFC command as shown in tutorial linked in blue.

I have run sfc many times but not from safe mode....as well as a start up repair type from repair disk hoping that it might pick up the original sys file or inf files.....no change.

Still not sure what is mean but when I click on the yellow triangle I get properties etc..will show that but it say cannot load mass storage so I will snapshot one the other are identical..The driver detail indicate error code 39...on Google searching I found 1000;s reference but no solutions

When I go down to USB sections they are all working but I updated every one..but did not uninstall as I was not sure where I would get replacements..when expanded they all reported they said they were working OK I show a shot of Standard Bus controller all others were same working

I also show my attempt at updating windows windows defender and the service pack..

I appreciate all your help.. thanks
