I'm having a problem with windows search
I found this MS article and I'm trying to follow instructions
"To resolve this issue, 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.
Once these files are deleted, reboot the machine. Once rebooted, observe that the Windows Search service has already started and is in process of rebuilding the Index."
I got to see the mentioned files but I can't delete some of them because they are in use.
Any idea how I can force delete them?
