Fix: Windows Search service on local computer has failed to start

If the Windows Search Service on local computer fails to start and even if you try to start it manually, and you get the following error message:
The Windows Search service on local computer started and then stopped. Some services stop automatically if they are not in use by other services or programs then this article might be of help.

This usually occur if there are missing subkeys or registry entries under the following registry location:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Search\CrawlScopeManager\Windows\SystemIndex

Or if there are corrupted log files at the following location:


To resolve this issue, KB2484025 recommends that you delete all files with .BLF and .REGTRANS-MS extension in the following directory:


Note: The files in the folder location above are hidden and will thus not be visible unless you set the system to not Hide Protected Operating System Files under Tools – Folder Options.

A system reboot is required, once the files are deleted. On reboot, you may observe a high CPU indicating that the Windows Search service has already started and is in process of rebuilding the Index.

    Hi Guys

    I have tried deleting the files in the TXR folder but it says that the files are in use by the system. Also tried going in safe mode but only deletes a few and they are all back when i reboot back into normal mode.

    Any suggestions would be great. this has been a nightmare
