Hi all.. Like many folk on here I have been messing about removing this, removing that from Win 10. This lead me to start using the "install_wim_tweaker" - Works well, not knocking it This got me to thinking how it works and I am slowly, very slowly.. NO. Even slower than that beginning to understand it. I like to do things manually then I know what's going on and I know nowt else is going on. I have a thread on the matter my little thread As always I want to do summet but don't really know what I have to do. I would like to learn how to amend reg keys via scripts. First though I am trying to wrap my head round taking full control of a reg key. been reading up on the net and well I find it a bit confusing. I found some info on "regini.exe" but when I write a little script I just get errors. I have this Picked up the codes from a site. the error I keep getting is It does not matter which reg key I point to or what combination of codes I put in, same error pops up. So I thought you clever lot on here could give me some pointers on where I am going wrong. by the way, 7-zip was the first reg key I saw. Not the one I am intending of amending.
