SFC Details inside. How do I fix these corrupted files?

JJbagood · 16 Oct 2012

I'm posting this from safe mode w/ networking as I don't know where else to turn.
I did a sfc scan and it stopped at 57% and I followed online instructions to obtain the sfc.txt. Here are the files unable to be fixed. The 2 corrupted are bcdedit.exe and wucltux.dll

Another thing to note. I've had this Lenovo y580 laptop for about a month and a half now and I've had to use "one key recovery" to wipe everything about 3 times. This thing will work fine for like 2 weeks then out of nowhere all these error messages and applications will start crashing. The HDD and memory health is fine from all scans from lenovo support they performed.

I only have warranty for hardware and I've been on the phone w/ them about a dozen times total. Now they want me to do a clean install by sending in recovery disks which would cost $60. Software warranty is extra $ which I'm very tight on. If I could manually try to fix this it'd be a godsend. Any advice is appreciated. Thanks. I also use MSE and malwarebytes so don't think its a virus it must be a flaw in the system. Thanks very much

Hello JJ, and welcome to Seven Forums.

Here's a clean copy of those files from my system in the ZIP file below. After you extract (drag and drop) them from the ZIP file to your desktop and unblock them, the TIP box below will explain how to replace them in your C:\Windows\System32 folder.

Tip

You will need to take ownership and set permissions to "Allow" your account "Full Control" of the original file in your current installation before you will be allowed to replace it with the extracted copy.

If the system file is in use and you are unable to replace it with the extracted copy, then:

Open a Command Prompt at boot.
Do steps 4B to 4D in this tutorial first to verify the drive letter of your Windows 7 drive. It's not always C: at boot.
Type in the command below to copy and replace the original file with the extracted replacement file.

Copy /Y "full path of extracted replacement file" "full path of original Windows 7 system file"

For example:
If the extracted replacement uDWM.DLL is on my desktop, then I would use type this in the command prompt at boot and press enter.

Copy /Y "C:\Users\User-name\Desktop\uDWM.dll" "C:\Windows\System32\uDWM.dll"

Hope this helps, :)

Yeah, this will only fix the ones in the System32 folder and not in the source file. That's fine as long as the files are working for you in Windows. :)

Time to nuke and pave...run crystal disk info to discard the disk has damaged sectors, then, backup your stuff and perform a clean install following one of the nice tutorials in this forum

I agree. It may be time to reinstall.
