查看是否成功排除 https://github.com/googlevr/gvr-unity-sdk/issues/1002@veqryn the workaround worked for me, the steps are:
Disable hyper-v (which will required a couple of restarts)
dism.exe /Online /Disable-Feature:Microsoft-Hyper-VWhen you finish all the required restarts, reserve the port you want so hyper-v doesn't reserve it back
netsh int ipv4 add excludedportrange protocol=tcp startport=50051 numberofports=1Re-Enable hyper-V (which will require a couple of restart)
dism.exe /Online /Enable-Feature:Microsoft-Hyper-V /Allwhen your system is back, you will be able to bind to that port successfully.
The reserved port changes as follows and InstantPreview will work.
C:\WINDOWS\system32>netsh interface ipv4 show excludedportrange protocol=tcp Protocol tcp Port Exclusion Ranges Start Port End Port ---------- -------- 49687 49786 49838 49838 * 49839 49938 49939 50038 50039 50138 50139 50238 * - Administered port exclusions.
Run the following commands to reset the dynamic port range to what it should be and reboot - this should fix things until Windows messes up the dynamic port range again. This is only for ipv4. I haven't looked at ipv6, but I'd assume it's similar.
netsh int ipv4 set dynamicport tcp start=49152 num=16383 netsh int ipv4 set dynamicport udp start=49152 num=16383
另外 hyper-v 启动与关闭命令 https://github.com/docker/for-win/issues/6689， https://www.poweronplatforms.com/enable-disable-hyper-v-windows-10-8/
Enable Hyper V - You can do this by running the following command as administrator. - dism.exe /Online /Enable-Feature:Microsoft-Hyper-V /All
Enable Hypervisor with following command - bcdedit /set hypervisorlaunchtype auto
