    PC lost 2/3 of its speed but gets full speed in safe mode.


    Hi,

    I tested my speed (PC connected by Ethernet cable) and a couple of days ago i noticed it had dropped to 20 Mbps (i usually get 60+) so having searched online i found it could be a conflict, a few threads pointed to AMD quick stream so i uninstalled it and it made no difference, i then tried safe mode and could not use it as i couldn't enter my password so searched again and found your excellent guide which helped me sort that problem (anyone having the same problem see link below) in safe mode i got my usual 60+ Mbps (my modem speed is 72 Mbps) so i rebooted and ran the tests again and it was back to 20 Mbps again, i assume this rules out a fault with the network card, cable and modem.
    I also tried my laptop on the same Ethernet cable and that gave the full 60 Mbps.

    I decided as the PC is a few years old i would take it back to factory settings and hope it would fix the problem which as you can see above it hasn't, has anyone any idea what can be causing this or how i can try to find a solution, thanks in advance.

    Wifi speed slow - 1/2 the speed of all other devices

    Try closing the peer to peer upgrade process. To do so, follow these steps:

    • Go to Settings>Update & Security.
    • Click Advanced Options.
    • Click Choose How Updates are Delivered.
    • Toggle off the switch.

    Also, kindly try booting your PC in safe mode and check if this allows you to utilize the full speed of your Internet connection. You can boot into safe mode by following the steps on this
    link.

    Computer Speed Slow in Windows Standard Mode But Normal in Safe Mode

    I have a Dell XPS 13 9350 Laptop. Running Windows it operates slowly. Checking the speed in Task Manager it shows processor usage of never more than 16% and processor speed of .38 Gigahertz and sure enough everything runs like molasses. When I boot into
    Safe Mode and check the speed in Task Manager it shows processor usage fluctuating above 16% and processor speed of 2.4 Gigahertz. Dell's online diagnostic testing doesn't show any issues with the hardware. I am a novice, but this seems to be a software issue
    rather than a hardware one.

    Any suggestions are welcome.
