Solved CMD caused steam to not open

Hello!

i am facing an issue with steam that i believe i have caused and i have no idea how to fix it.

basically steam was running fine since i installed it many months ago BUT today i decided to run some commands in CMD (as admin) because i thought they might give me better internet connection and clear out junks.

the commands:
ipconfig /flushdns
ipconfig /release
ipconfig /renew
netsh winsock reset
netsh int ip reset

i ran these one by one into CMD and then restarted my laptop and then tried to open steam but it didnt.
note: steam was working fine that day. i opened it chatted with friends i played a few minutes of a game but right after these commands and the restart it stopped opening.

details i can provide:
so i open it and i think (i am not too sure) it shows the classic update window for a split second and then closes (some times it doesnt open the update window) and then nothing happens. steam just doesnt open. BUT i can see it running in task manager.
i see steam, steam client service, and steam client webhelper in task manager.

what i have tried so far:
i killed it in task manger and tried again,
i deleted some steam related files such as package and logs,
i went and delete everything except steam.exe and steamapps,
i uninstalled and downloaded and installed steam again,
i opened a new local user account on my laptop and tried it there ,
i tried to reset networking settings,
i tried to (BUT was NOT successful to give it an honest try since i was tired) to redo the commands i showed you in a desperate way because i have no idea how to reverse them.
and none of these solutions worked for me.

feel free to ask ANY questions and i will try to provide as much info as i can

also i am on windows 11 AND i have an asus rog strix.
and i also noticed that the RGB colors on my laptop have stopped working. meaning the lights are off and i dont know how to turn them on since armoury crate is NOT opening. armoury crate not opening COULD be a separate issue since its been months since i last checked armoury crate so i dont know. now the RGB issue i dont think is just a coincidence since it happened with everything else.

Try uninstalling Steam using Revo Uninstaller and reinstall it and the command you have used is for resetting TCP/IP protocol suite and should be used with caution.

hey thanks for the solution. actually i did found a fix.
i did many things at once. i first uninstalled steam then restored network firewall and defender and antivirus to defualt and then i deleted ping improving and conncetion blocking and improving tools that i had which were hone, simplewall, cloude flare warp.

and only then i restarted my laptop and installed steam and it worked.

thanks again for help.

by the way if its no bother can you simply explain to me what happened and why did this fix it? i am know nothing about networking or coding (if i did i would not have put myself in such situation) but i want to know what was happening.

For future use you can just reset the network in Windows settings instead of running commands.

Resetting the network stack (by using the command line) is relatively safe. What you neglected to mention in the first post, is you have 3rd-party firewall and VPN software on top. When the stack gets reset, all the bindings those apps depend on are re-initialized. And you have to add them back on top again.

Which is why in @KevTech's screen example, the Settings app literally instructs you to reinstall your VPN client and other software.

If you're experiencing an one-time network glitch, simply reboot Windows and see if the problem goes away instead of using reset.
