SDK setup error: a folder failed to be renamed or moved

During updating your Android SDK components from eclipse (running in windows) you may receive the following error message:
a folder failed to be renamed or moved...

the message suggests that you turn of your anti-virus.
I did so but still recieved the error.
I terminated the adb.exe from the processes but still not solved.

the problem is that the update batch is rin from android.bat file inside tools directory. update requires that this folder is renamed temporarily but since Windows 7 locks it the process halts with this error.
so a workaround for this is to copy the tools folder, paste it in te sdk directory, name it tools_temp for example and run android.bat from this directory.

the update shall go smooth, after finishing delete this temp folder and launch eclipse and it will work fine.

note:
after restarting eclipse you may recieve this error
This Android SDK requires Android Developer Toolkit version 10.xxxxxxxxxx the current version is 9.xxxxxxxxxxxxxx.

this is because the ADT plugin needs to be update after updating software components, go to http://developer.android.com/sdk/eclipse-adt.html and follow the instructions and everything will work after this.
