Windows.old continuously creates files after each min.

Ok firzon mate some system psecs would help here so please follow this
SYSTEM SPECS
Now before we can help we do need to know what is in your machine so please do this System Info - See Your System Specs - Windows 7 Help Forums
or either enter the specs of your system in your forum profile the specs will appear when we click on that little box bottom left of the post screen it is for me the preferable option as it is easy. As you may appreciate it is very hard when you don’t know what one is working with for example a diesel or petrol engine.

Now the copy of your Windows just where did you get it - did you buy a now OEM ir did it come with the machine?? I doubt it was the latter and am wondering if you didn't put that copy of Windows who did??

PLus it would be an idea to also run these
SFC /SCANNOW Command - System File Checker - Windows 7 Help Forums
Disk Check - Windows 7 Help Forums < if necessary include the /f and /r in the command line as per Option2

Windows.Old is created when you do a upgrade installation. Did you start an upgrade to Win 10?

Hmm that's is really odd Mega I have an old folder with nothing in it on a clean install from a new OEM onto a cleaned drive??

Makes no odds as there is nothing in it maybe a chip on the drive didn't get cleaned properly??

If you boot from a win 7 installation disk and do a clean install on a drive without deleting or formatting the partition it will also create a Windows.old with all folders from the previous installation.

Hmm well I di that mate I just cleaned the drive and created an active partition - no worry really as there is nothing in there anyway.
