Windows 7: Windows Update fails to update, error code 800F081F

Windows Update fails to update, error code 800F081F

My Windows Update has been failing to update for a while now and I can't seem to find the solution. Here's the run-down of what happens step by step:
  1. Launch an update scan for Windows Update
  2. It scans for a few seconds then says:
    Quote:
    Install new Windows Update software

    To check for updates, you must first install an update for Windows Update.
  3. Once I click Install it begins to "Install and Update," but then immediately returns to "Checking for Updates."
  4. The next box I see says:
    Quote:
    Windows could not search for new updates

    An error occurred while checking
    for new updates for your
    computer.

    Error(s) found:
    Code 800F081F

This happens every time I've attempted to update. After looking up the error code, I found the main Windows site that gave me the following explaination:
If you receive Windows Update error 800F081F, it means that Windows Update or Microsoft Update cannot determine the cryptographic service provider, or a file Windows Update requires (named catalog store) is corrupted.

I've looked through multiple Windows forums and How-To's and have tried all the fixes I found. SURT, sfc/ scannow, the standalone download for WU, Windows Update Diagnostic, multiple malware scans, and Microsoft Fixit. Ultimately, I always get the same error code, (800F081F).

I should also say this problem has been here for a few months now, and it's becoming more worrisome as more time passes. The longer I wait to get this fixed, the more I fear I will be hurting my computer.

Any and all help is greatly appreciated, and I will do my best to cooperate with any instructions or requests.

Thank you.

Mookey

Hi Mookeylee & welcome to Sevenforums.

Please follow Windows Update Posting Instructions

We need to see the logs to determine the cause of the error.

Worst case scenario, and last resort, repair install windows 7. No big deal I just did 2 yesterday win7x64 Home Premium. Brink posted a great tutorial Repair Install.

Here's the missing manifest and winsxs folder/files:

  1. Open Packs.zip extract to desktop
  2. If the below directory/folder CheckSUR does not exist create it.
  3. If the below directory/folder servicing does not exist create it.
  4. Copy and paste winsxs folder into: C:\Windows\Temp\CheckSUR\
  5. Copy and paste manifests folder into: C:\Windows\Temp\CheckSUR\servicing
  6. run SURT again.
  7. Download packages.zip
  8. Please post CheckSUR.log located at: C:\Windows\Logs\CBS
To create a folder right click inside window. Popup choose new>folder. right-click new folder, popup choose rename. Type the appropriate folder name. Press <enter>

Did everything you said and still got the same results and error code (800F081F). #7 confused me a bit, though. Don't know if that zip file is the same as the Packs.zip you already provided, so I'm skipping right to #8 for now. Anyways, here are the logs.

Was up from 4:30 am, long day, mistake on #7.
Doesn't appear as though SURT picked up the folders.
Maybe incorrect placement of folders.
To alleviate possible errors in file/folder placement try this:

  1. Download SFC.fix.exe by Niemiro and place it on your desktop.
  2. Download attachment to desktop as well.
  3. Drag & drop SFCfix.zip (attachment on top of SFCfix.exe (download).
  4. Please post SFCfix.txt.

If that doesn't correct your issue. Repair install may be in order.
Repair install preservers all your programs, files, folders, pictures, music,video, etc.

I understand, man. It's all good.

Sorry for the delayed responses, but I had errands to run in town. Anyways, I did as you asked. Here is the file.

Not a problem with the delay, I have a life to besides here.
Awesome,
Gotta give Niemiro kudos for the SFCfix.exe at Sysnative Forum.
Run SURT again and post just the CheckSUR.log & see how we did.
C:\Windows\Temp\CheckSUR\CheckSUR.log
Still no luck on the other missing files.
Your error code has multiple reasons.

It looks like nothing really changed unfortunately. At least from what I can tell.

Tell me again exactly where to place the files you provided in the packs.zip. I'm not confident I placed them in the right location.

The winsxs folder is placed in C:\Windows\Temp\CheckSUR, overwriting the files already there.
The Manifest files are place in C:\Windows\Temp\CheckSUR\servicing, (a folder I had to create, mind you).

But there is also the MSU folder that contains a servicing subfolder with both manifests and Packages folders. Then there is also the Manifests folder in my winsxs folder. All in all I'm second guessing my original placement and wondering if I need to place the files you provided me in another section.
