[Solved] Corrupted system files on win 8.1

Hello folks. Apparently I have some corrupted system files I found when I ran the sfc scan from the command prompt. I was trying to find out just why Windows Defender would no longer work. I uninstalled every possible anti virus app I could find on my pc and when that did not work I thought maybe I had some corrupted system files preventing Defender from working. I found that yes I did have some corrupted sys files but now I do not know how to repair/replace those files that are corrupted nor do I know what files they are. I will attach the scan results. Is there a way to easily accomplish this without a lot of complications?
Thanks and greetings from the Philippines. Dave

 

You can try a Repiar Install Dave:

I went to that site Rich but it turns out to be for Win 7 only. They also said you can only use repair install with the installation disk for the same edition that you are using.
My problem is I have 8.1 and my installation disk is for 8.0 so I don't think that will work for me. I got 8.1 by updates.
Thanks, Dave

 

Sorry I forgot that.
Here is how to get the disk to do the refresh:

No problem Rich. Unfortunately I may be in a bad situation. Let me explain my downloading restrictions. I have very little band width using the cell phone tower. No broadband. It took three days and three nights constant downloading just to get 8.1 through updates. I tried to download using the ISO route and saving to my thumb drive but after two days of downloading I got the error "unable to download", so I lost everything. I was just lucky to get 8.1 via updates.
Is there any way I can replace just the sys files that are corrupted without downloading the entire ISO? I would love to have a thumb drive with it there for future use but unless I can figure a way to increase my download speed, I think I'm sunk.
Thanks, Dave

 

The only thing I can think of wold be buy a dvd on eBay but you have to be really careful as they do police it but there are still bogus dvds that get listed from time to time.
Read client feedback for every posting is the only way to be sure. If yours is a "branded" computer you need to buy an "oem" version. The safest way to be sure you have that is buy a Dell dvd with a code as that has to be oem.

 

Thanks but that's not an option I can do from where I am. I will have to reinstall a virus protection app as I do not have any protection at this point.
Have a great day, Dave

 

You can try go to windows update and view installed updates. Uninstall update KB3000850 and reinstall it. From your log it looks like the corrupt files belong to this update. Here is the download https://support.microsoft.com/en-us/kb/3000850. The link for the download is at the bottom of the page.

 

I could not find the update in installed updates. Since I updated to 8.1 from 8.0, it is probably in that upgrade. I could not download the update from microsoft as I kept getting the error "unknown network error." So then I tried to download the ms Media Creation Tool and save to my usb flash drive. It took four days and nights but I was finally able to get it. But then I found out you cannot boot your pc from media usb unless you previously had 8.1 on your pc to begin with. I originally had 8.0 so the usb download does me no good. the only thing I can think of doing is to boot in 8.0 and then upgrade again to 8.1. That will take a long long time.
All I want to do is be able to boot my 8.1 from either usb or a cd. There are times that things happen and a reboot is necessary as in my case now with corrupted windows files.
Thanks

that particular update, KB 3000850, is a massive file of 400mgs. That is probably why I cannot download it via the slow connections I have.

 

Why doesn't some gov't agency do something about your broadband performance I mean that is not a primitive area?

 

Ya well, this is the Philippines. Corruption is everywhere. It is frustrating for a western alien but we get used to it and just try to work around it. I just recently downloaded AVG virus protection because I am not protected as Win Defender won't run. But I can't even get AVG to update. Its been running two hours now.
Anyway, to get back to the win sys files, I let downloads run for four days and nights and finally completed the win media creation tool for 8.1. I have not tried it yet because I heard that I cannot use it unless I had 8.1 original to begin with. Since I updated to 8.1 from 8.0 via win updates, I wanted to get some advice as to whether or not I should try it.
Thanks, Dave

 

Dave everyone will probably give you a different answer but I am going to say don't rush into it as there are many problems out there that need to get solved first and you have almost a year to do this.

 

Yes Rich, you are right. There is a rumour that in three months broad band may come to my area.
I finally did get the update KB3000850 downloaded. True to form there is a problem. When I tried to run it I got the error "the data is invalid". Just can't win! I did find this update in "installed updates" so I know at least it did download via win updates originally. Will Windows eventually replace that update over time? Will they realize through some feed back that the win sys files are corrupted?
Thanks, Dave

 

Sometimes that means something else was needed to be downloaded before that update but if it is just the update itself is corrupted I imagine it will be fixed. Who knows but that poor internet connection you have didn't mess it up also so you will wind up waiting and hopefully that whole situation will be improved as you heard.

 

FYI. I found the solution at www.tweaking.com. I ran that at the command prompt and it evidently reset all my windows files. At least when I run sfc scan there are no problems noted. Thanks Dave.

 

Hey persistence pays off good job.
