How to Fix KB3198586 Failing to Install on Windows 10

The cumulative windows 10 update KB3198586 is known to have some installation issues. Many users get errors like Windows update stuck at the white ring, Windows reverting back to the previous version and many more.

If you are facing the same troubles in installing this cumulative Windows 10 update then the most likely reason of this might be corrupted system files. Fortunately for you that there are a few ways to fix this problem.

If you are one of those people who transferred their files from C to E drive and created a directory junction because of storage problems then you should start from method 5. Otherwise, start from method 1 and keep going to the next method until your problem is solved.

Method 1: SFC and DISM checking

SFC is Windows System File Check utility that can help detect and fix problems with system files. DISM is Deployment Image Servicing and Management used for servicing Windows Image or a virtual Hard Disk. Both of these utilities are a part of Windows 10 so you don’t have to download anything.

Run SFC

1. Hold Windows key and press X (Release Windows Key) then select Command Prompt (Admin)
2. Type sfc /scannow and press Enter

Results

It will take some time and will give you the results. The results can be

1. Windows did not find any integrity violations
2. Windows Resource Protection found corrupt files and repaired them
3. Windows Resource Protection found corrupt files but was unable to fix some (or all) of them

It’s always a good idea to run SFC method 3 times to make sure all the problems are fixed.

DISM

Now it’s time to run DISM to make sure everything is fine. Keep in mind DISM is only available for Windows 8 and 10.

1. Hold Windows key and press X (Release Windows Key) then select Command Prompt (Admin)
2. Type DISM /Online /Cleanup-Image /RestoreHealth and press Enter

If you get an error cannot find resource files then go here, click Using the tool to create installation media (USB flash drive, DVD, or ISO file) to install Windows 10 on a different PC (click to show more or less information) and follow the steps provided there. Once you are done, perform these steps

1. Hold Windows key and press X (Release Windows Key) then select Command Prompt (Admin)
2. Type DISM /Online /Cleanup-Image /RestoreHealth /source:WIM:X:\Sources\Install.wim:1 /LimitAccess (X is the drive letter where your ISO is e.g. F) and press Enter

Now you should try to install Windows Cumulative update again and it should most likely work now.

Method 2: Troubleshoot from Windows

1. Hold Windows key and press X (Release Windows Key) then select Control Panel
2. Type Troubleshoot in the Search bar (top right corner)
3. Click Troubleshooting
4. Click Fix problems with Windows Update
5. Click next. Now Windows will find and fix problems

Method 3: Clearing SoftwareDistribution folder

Sometimes the update file itself might have a problem and to solve that you have to delete the files from the SoftwareDistribution folder located in your C drive.

1. Hold Windows key and press X (Release Windows Key) then select File Explorer
2. Write C:\Windows\SoftwareDistribution\Download in the address bar (located on the top-mid of file explorer) and press Enter
3. Hold CTRL and press A (Release CTRL). This will select all the files in the folder
4. Right click on the selected files and select Delete
   

Method 4: Uncheck download from multiple places

1. Click Start > Settings
2. Click Update and Security
3. Click Advanced options
4. Click Choose how updates are installed
5. Click (turn off) update from multiple places

Method 5: Changing Registry Keys

This method is NOT for everyone. This method will work for people who followed this method and moved files from C to E drive (because of storage space issues) and created a directory junction.

This solution will also NOT work if you did not use a secondary drive for user directory. So make sure this method is applicable to you before you proceed.

1. Hold Windows key and press R (Release Windows Key)
2. Type regedit and press Enter
3. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion
4. Click ProfileList once
5. Create back up
   1. Click Default (with the value %SystemDrive%\Users\Default)
   2. Click File > Click Export
   3. Go to Desktop (or any other place where you want the backup to be)
   4. Write your filename and click save

5. Repeat the steps from 1-4 for ProfilesDirectory and Public

6. Double click Default (with the value %SystemDrive%\Users\Default)
7. Type E:\Users\Default and press Enter
8. Double click ProfilesDirectory
9. Type E:\Users and press Enter
10. Double click Public
11. Type E:\Users\Public and press Enter

Now your update should go easily.

If something goes wrong or you simply want to restore the backup Registry keys then follow these steps

1. Hold Windows key and press R (Release Windows Key)
2. Type regedit and press Enter
3. Click File > Click Import
4. Go to the place where you saved your backup Registry Keys
5. Click Open
