Well, okay, I appreciate your concern for my possible disaster, so let me give some more detail in case any others are listening and care. First of all, I'm in no danger of problem with doing this. Ever since I became aware of SSD (solid state drives), I have been set free from fear of Windows boogymonsters. I was concerned about what Windows actually needed, so I cloned my boot drive and did everything there as a test. As for my being disenclined to believe absolutist dogma and declarations, I have a long history of seeking out the truth of matters, and not just believing what I'm told. I didnt trust your declarations, but that UK website you mentioned looked very useful at getting more general info, and I will read and consider it when I have the time. I am less inclined to read the Microsoft one, as I have been using Dos and Windows since it began, and know it is full of convoluted bulloney, and their help system has NEVER been helpful in the many times I have wasted hours reading their crap. I have much to say about what a nasty, insecure system it is, by default, and each new version I get has all the same stupid issues, plus always a few new nasty behaviours and features to figure out, if possible... but that is beyond the scope here.
What I do believe and trust in, is the so-called scientific method, of trying things and observing what happens. Thus I blew the Boot folder away, and observed zero issues thus far. As I said, I am not doing any multi-boot stuff. I do use Cygwin, which I love, when I need some unix tools to get things done.
I just went thru the process again with another clone, and will let you see what I did, in case you or others want to try it at home. But of course, I strongly recommend doing it on a clone, just in case you do screw up. Attached below are some images showing how to get rid of the"Boot" folder. First, select the Boot folder and bring up the properties dialog. Select the Security tab, then click the Advanced button. Click the Change button for the Owner property, set it to Administrators. Check the Replace owner on subcontainer box and click Apply. You get a popup telling you to close the properties before continuing. Do that, and bring it back up. Now select the Administrators for the folder. Check the box to "Replace all child object perms" and click Enable Inheritance. You get a scary Security warning. Click Yes, and ok to close the dialog. Now you can delete the Boot folder, but only as Admin. At present, I have no idea what I actually changed inside Windows perms, but hope that UK website will better inform me just what that was all about.
