   Warning

Possible errors returned by commands

Could not find <file name> -You may not have some file but it's normal and you can safely ignore this error.

The process cannot access the file because it is being used by another process-As message say unable to delete files.If remains succesfuly done commands does not fix problem you have to repeat this step from WinRE level or
any liveCD (See METHOD III)


As you can see in this example unable to delete some files in TxR folder .If remains commands does not fix your problem you have to repeat this step from WinRE or linux.



METHOD III (from WinRE level)

//apply only if unable to complete all steps in METHOD II and problem still exist//

   Warning

Mostly cases OS is installed on first partition and WinRE can see it also as C:.If you have installed OS on other partition you have to change drive letter in my commands i.e if you have OS on second partition the proper first command for you will be cd /d D:\Windows\System32\Config\TxR and so on for remains commands below.For precaution you can check partitions status in diskmgmt.msc in your OS,before you boot installation disk

Boot your Windows installation disk,choose language>>repair computer>>command prompt and type:

cd /d C:\Windows\System32\Config\TxR

press ENTER

attrib -r -s -h *

press ENTER

del *

press ENTER

cd C:\Windows\System32\SMI\Store\Machine

press ENTER

attrib -r -s -h *

press ENTER

del *.tm*

press ENTER

del *.blf

press ENTER

del *.regtrans-ms

press ENTER


From WinRE there is no problem to make all commands.As I said before you can ignore error about missing files -you may not have all log files and it's normal

If you hate WinRE and command prompt you can use any live CD or linux i.e Ubuntu too.By using linux you have to delete following files:

in Windows\System32\Config\TxR :

-delete all files

in Windows\System32\SMI\Store\Machine:

-delete only files with extensions *.tm*,*.blf,*.regtrans-ms
