Hello, I have been using genuine Windows 7 Ult for several years now, and have one big problem, namely the appalling length of time it takes to open the context menu.

Does anyone please know how to fix this problem?

I will be very grateful for any suggestion.

   What do you mean by context menu?  What are you doing to open the menu.
   When you say context menu, I think of what pops up when you right click on something.  This should be different depending on where you are right clicking.  When I write a program, I specify what comes up on a right click.  I tried right clicking around in Win7 and did not have a problem with speed.
   The thing that is slow for me in Win7 is the submenus of items in Start (the items that have an arrow next to them).  Items like Downloads and Recent Items, if you have them set up to show a submenu, take a long time to appear.  Usually they are faster the second time they appear.  I assume they are slow because Windows is trying to find the items to put on the list.

Thanks Ray. I am talking about right-clicking on program folders and executable files, particularly installers (in order to get the "Run as Administrator" command) listed on screen, in whichever file manager I am using. This is usually PowerDesk 9, although I am also trying out xPlorer2 v.2.5, but get the same problem. I also get the same effect when using Windows Explorer on it's own.

I am using a PC based on an Intel 6/C200 chipset, and iCore 3 CPUs with 16 Gig of Ram

I hope my problem is now clear to you, and look forward to getting your advice!

   Those lists are compiled from what is in the HKEY_CLASSES_ROOT section of the registry (you can view this by running regedit.exe), specifically, what is in the shell folder of the file type you are right clicking on.  For example, if you right click on a folder, the Folder key under HKEY_CLASSES_ROOT is one of the places the program looks to find out what to put in the context menu.  I think * is another key that is consulted.  If you look at the shell folder of these keys, you will see the items on the context menu.
   I would assume that Windows Explorer will be faster than the other file managers that you are using, because the other file managers have to indirectly use the processes that Windows Explorer uses directly to make the context menu.
   As to what is slowing it down, I don't know.  Maybe you have a lot of items in the HKEY_CLASSES_ROOT section of the registry (I have a lot of items but mine is not slow), maybe there is something messed up in the shell folders, maybe you installed a program which is putting itself on the context menu but doing so in a slow way, or maybe the registry is corrupt in that part of the registry.
