Upgraded to this version from 1903. Horrible lag time and internet is very slow. I have done all the 'fixes' recommended, like the reg key, reload drivers, dism and scans, etc. Nothing works. Tried going back to 1909 but that version had worse issues. Any help would greatly be appreciated.

    Starting from 1903 (or 1909) this involves a download of several GB. If you have slow Internet the best option is to download an iso first. Once that has completed you can mount it and run setup.exe. The actual installation will be faster and probably more reliable. Also if installation does need to be repeated there is no need to repeat the slow download.

    @Sue Blue
    Hi,
    The fastest way to get the upgrade is through Media creation tool or ISO file.
    Please download Media Creation Tool from the link below and select Upgrade this PC at the first screen:
    https://www.microsoft.com/en-us/software-download/windows10

    This will save your files and apps while bringing you up to the latest version by the most stable method. It will also bring all of your Updates current and solve most problems since it reinstalls Windows.

    Hope above information can help you.
