      You may as well have a go at booting from a W10 installation DVD that you make with the MS media creation tool. And I do mean a DVD not a USB srick.

      Some PCs and especially laptops with secure boot enabled, or not fully disabled, just will not boot anything other than an MS OS or a copy of Linux with a special loader.

      If you do get the W10 DVD to boot then you can try any of the test and recovery options.

        I really wouldn’t try it JayCD and especially not on an efi system. If you really want to try it then backup ALL your settings and data first because the chances of a non booting system are fair to good !

        If you only want to put the latest W10 on your ssd then I would disconnect your HD and boot from the installation DVD or USB stick.

          My best guess is that the adobe baground process is looking to connect to something before timing out. Could it be looking for an e-reader ?

          I know you have done an uninstall/reinstall but Adobe products have a nasty habit of leaving config files and registry settings behind.

            This is purely academic but the wiki is a bit confused about memory management, at least on windows.

            The wiki states that every process has the address range of every other process mapped into it. This is NOT the case.

            The Windows memory manager will stamp on any process that tries to access the private memory of another process. Even shared memory is not really an exception as it is accessed via a kernel call.

            As I have said before the problem we now have is because the systems Kernel memory IS mapped into the address range of every process.

            The windows memory manager will not bat an eye lid if a user process tries to access kernel memory but this should not be a problem because the CPU should imediatly recognise a privalege violation and generate an exception. It turns out though that there are ways around it.

              My system tested as not patched on all counts ?.

              Oh well. I will just have to hope that the anti virus people stay on top of any malware that may use these exploits. At least my browser says it’s patched ?

                Gibson Research has released a small tool called InSpectre that will tell you if your system firmware and OS have been patched.

                Just Google Gibson Research and look in freeware.

                  I don’t know of a universal cheat engine but they do exist for some games. Does punk buster still exist on steam though ?

                  I like id software games BECAUSE i can pull up the console when i like and cheat just enough ?

                  My stratergy is to try a sticking point for about an hour then cheat because as mentioned above i like to see the end of a game. I paied for the whole thing after all.

                    Audio CDs are odd things as far as a computer is concerned. There is no file system as such and so no file system driver in Windows that i’m aware of. Windows leaves Audio CD playing and ripping upto player apps. The first time you insert a CD windows will ask what app you want to open it with but then thats fixed for that drive for all CDs unless you change it.

                    A problem occurs if the association becomes corrupt or points to a faulty app. Windows will appear to ignore the disk.

                    Fixing the problem can be as simple as just changing the file association for .cda files to Windows media player. WMP is the best choice for this problem.

                    Corse your drive could just be stuffed so its worth inserting a CD ROM disk into it, if you have one, because they DO have a filing system (CDFS or UDF) so don’t have this problem.

                    On a side note .cda files are not real tracks. CD playing programs create .cda files as an index to tracks on a real disk.

                      Dave

                      Just a quick bow to your superior practical knowledge on 10baseT networks ?

                      A network hub is just a tiny bit more than a wiring concentrater because of the sesperate RX and TX pairs used. With just 2 computers a simple crossover cable will do but with more than that a bit more logic is required. A hub still does not analise packets though, it only detects electrical activity on its ports and the very simplest hubs can’t do duplex working either

                      I read your link about hub less connections though. It may be posible to get a few computers connected if their NICs support auto RX, TX senceing.

                          Yes again Dave ?

                          A backbone system with collision detection. If you have a large network without a switch you will get packet collision causing slowdown. I think they say 10 devices per segment is ok

                            Sorry to go on BUT..

                            ethernet is base band with collision detection. Everything is sent everywhere if you don’t have a switch. A hub is not a switch ?

                              Base band T works the same as coax backbone. All packets everyware.

                                Dave .Yep a hub is just a wire splitter. No switching. Every packet goes to all ports. If you can get the book i recommended have a look ?

                                  More or less what I was afraid of.

                                    Really if you have a mobile or any sort of online account (let alone an MS account) THEY know who you are ?

                                      Perhaps a bit more explication.

                                      Ethernet is a backbone system. All packets get broadcast on all ports unless they go through a switch or roughter.

                                      A good book is jump start TCP/IP

                                        An Ethernet splitter should work. A hub is the same thing. Just won’t do any packet switching.

                                            I just noticed I didn’t describe what a software patch would involve so here goes.

                                            Each process keeps two stacks of memory with one for user mode code and one for kernel code. These stacks contain, among other things, the contents of CPU registers when the CPU switches between user mode and kernel mode.

                                            When a user mode thread calls an OS service and switches to kernel mode the only thing that really changes is the stack that is used. The OS code is said to run in the context of the process that called it.

                                            This is how it works now but the patch would seriously change things. A patched OS would remove kernel address space from the context of all user mode processes so the kernel code in a service call would have to run in its own precess. This would involve a full context switch every time a user thread called an OS service.

                                            A multitasking OS performs a context switch every time it switches tasks but this is not trivial and you would not wan’t to do it every time a thread requested disc I/O for example.

                                            Unfortunatly this is what a patched OS will have to do.
