How to repair errors updates (Windows Update) Windows 7,8 Y 10

Windows 10, apart from being a good operating system, as in all, could not miss Windows Update errors, but this time it seems that are worse than before. I will try to make a Guide to Resolving failures Windows updates 7, 8 Y 10.

1 – When you of any failure or mistake, first of all be spending the repairman Microsoft Windows Update (Always restart the PC after each repairer):

2 – For all Windows, if it does not work, the following will these commands from the command prompt (cmd.exe) and executed as administrator:

sfc /scannow : if this says it has corrected flaws, return it to happen until it says it is ok

3 – in Windows 8 Y 10 , when the sfc not tell you that is flawed, Execute these commands in this order, one after the other, not both.

Dism.exe /Online /Cleanup-Image /startComponentCleanup

Dism.exe /Online /Cleanup-Image /RestoreHealth

4 – For all Windows. If still not working, go this route and Eliminate everything there inside of her:


5 – For all Windows. Stop the Windows cryptographic services and rename this folder:

C:\Windows\System32\Catroot2 to catroot2x , (windows recreates the solito)

6 – In cases strangers, you may need repair startup in Windows 10. For this, We need the installation CD and then repair repair windows-advanced-startup options or boot.

7 – If you are going to upgrade to Windows 10 or within W10, uninstall or disable the antivirus.

8 – Spend a registry cleaner like CCleaner.

NOTE : These are the basic steps to repair and secure Windows updates in general, and even so you can not solve or those of a specific error (type 0x80004005), put it in comments and I'll see if I find out.
