  1. Let’s step back for a few moments & consider the BIG picture: We are discussing the procedure for inserting a thermal-stent into the heart of a living man… What! We’re only discussing moving files on & off a device using USB? And the question is: “Why after 5+ YEARS can’t Microsoft figure out how to do this in Windows 10 (the one OS to rule them all) at even 33% of the speed that Linux can do it?”. Is this simply because Windows/Microsoft sucks? Well, yes – that too… but the situation is more nefarious. Windows is SPYING on you. It is screening those copied files for information to be used in various ways. It’s doing it for marketing. It’s doing it to keep a backroom deal struck with the DOJ waaaay back in the 90’s when Bill Gates found himself charged with giving Netscape a swirly in the public toilet by – bundling Internet Explorer with Windows (notice how Bill Gates left the CEO position shortly after). If you don’t understand this or the reasons MS can’t seem to fill security holes or fix technical problems that a high-school sophomore could … OR related media subterfuge regarding the DOJ settlement with MS – then you need to look deeply into a mirror for a moment. See the sheep – looking back at you?

  2. I have a problem. Win1O. Downloading data from the Network, the size of which is 1 GB or more, is accompanied by an increase in the data transfer rate, which is about 5 MB/s. The same thing happens when I archive the data in the 7zip program. In the first and last cases, the following happens: the sound in the speakers or in the headphones begins to buzz as if a garage vacuum cleaner is working, the system does not respond to anything. It’s like my computer is frozen. This can last for more than thirty minutes. I’ve disabled antivirus and security services, but it doesn’t help. I don’t know what to do. Help me(Microsoft themselves do not know how to help me)please.

  3. turn off real-time virus protection
    turn off or pause indexing speed things up tremendously for disk to disk.
    obviously best to be offline and perform virus check after copy and turn services back on

  4. To locate Optimise drives
    Right click the start button
    Select search
    Search for Services
    You’ll find Optimise drives there, not in the registry.

  5. 3. Now, In the registry editor locate Optimize drives.

    4. Right Click on it and choose Properties .

    where in registry, find doesnt work

  6. I like the part where you say to load the registry editor, but then the next steps are clearly performed though the management console.

    I wouldn’t trust any of these instructions one bit without verifying them somewhere else first.

  7. I think I’m used to having documentation that gives me a little more information of what occurs when taking a step. Here, I must blindly follow the instructions and hope you aren’t setting me up for something dire :-). I pretty much trust you people. This is just a FWIW from a lower tech person.
