Tutorial
Files update.cat,update.mum,update-bf.cat,update-bf.mum

Almost all the extracted components have the same name as those contained in subfolders of C:\Windows except for those
files that are listed in this section,however, giving them the correct name is not difficult.Extracted *.cat,*.mum files have the following form:

Package_{number}_for_{update ID}~31bf3856ad364e35~x86~~6.x.x.x.cat (for system 32bit)

Package_{number}_for_{update ID}~31bf3856ad364e35~amd64~~6.x.x.x.cat (for system 64bit)

so then correct name for update.cat will be

Package_for_{update ID}~31bf3856ad364e35~x86~~6.x.x.x.cat (for system 32bit)

Package_for_{update ID}~31bf3856ad364e35~amd64~~6.x.x.x.cat (for system 64bit)

and of course correct name of update.mum

Package_for_{update ID}~31bf3856ad364e35~x86~~6.x.x.x.mum (for system 32bit)

Package_for_{update ID}~31bf3856ad364e35~amd64~~6.x.x.x.mum (for system 64bit)

The file update-bf.cat we need to compare with the files with that names

Package_{number}_for_{update ID}_bf~31bf3856ad364e35~x86~~6.x.x.x.cat (for system 32bit)

Package_{number}_for_{update ID}_bf~31bf3856ad364e35~amd64~~6.x.x.x.cat (for system 64bit)

so proper name for update-bf.cat,update-bf.mum will be:

Package_for_{update ID}_bf~31bf3856ad364e35~x86~~6.x.x.x.cat /mum (for system 32bit)

Package_for_{update ID}_bf~31bf3856ad364e35~amd64~~6.x.x.x.cat /mum (for system 64bit)

EXAMPLE

unpacked KB980302 for Windows 7 32bit


for this update update.cat/mum will be

package_for_kb980302~31bf3856ad364e35~x86~~6.1.1.0.cat /mum

and update-bf.cat

package_for_kb980302_bf~31bf3856ad364e35~x86~~6.1.1.0.cat /mum

Note

The 4th and 3th char from the right in package name indicate kernel version of system
6.0 -Vista/Windows Server 2008,6.1 -Windows 7/Windows Server 2008 R2

REPLACING CORRUPTED FILES

When you have already prepared all required files from different sources you can now replace corrupted files
by using any below method.

METHOD I

Warning

This method affects only on C:\Windows\Servicing\Packages and C:\Windows\WinSxS\Manifests folders.This method will not work if you have damages in other locations.



1.copy all *.cat,*.mum files to C:\Windows\Temp\CheckSur\Servicing\Packages folder,and all *.manifest files to C:\Windows\Temp\CheckSur\WinSxS\Manifests
2.Run Readiness Tool again

METHOD II

1.Navigate to folders where you have corrupted files,takeownership of these folders and add your account to have
full control
2.Replace corrupted files
3.Restore original permissions

Tip

I do not recommend using this method on WinSxS folder,practically there are many obstacles with changing permissions for it,i.e files using by any process.My suggestion:if you have damages in WinSxS
I or another qualified WU Tech walk you through it if you wish.

Yes, I will fix your computer.
