Try deleting the appcache folder in your Steam directory, resetting the network stack with netsh winsock reset, and launching Steam in Safe Mode with Networking. If that doesn’t work, create a new Windows user profile and test Steam there.

i fully purged steam out of my computer and re installed it and it did nothing and rn i'll try the new windows profile once i find out how to do that

When steam is running in the "background," does Windows taskbar show "Steam" running? If so then try this:

1. Find the desktop shortcut for steam.exe or create one if none is present.
   
2. Right-click the shortcut and select "Properties"
   
3. Select the "Shortcut" tab and then add a single space and the text (without quotes) "-cef-disable-gpu" to the end of the text in the "Target" box. For the default Steam install, the text in the target box should read (with quotes):
   "C:\Program Files (x86)\Steam\steam.exe" -cef-disable-gpu
   
4. Click "Apply" and "OK."
   
5. Completely exit Steam; end "Steam (32bit)" process with Windows Task Manager if necessary.
   
6. Double-click the modified shortcut.
   
7. If Steam is running normally, then be sure to go to Steam -> Settings -> Interface and then disable "GPU accelerated rendering in web views." Afterward return the shortcut to how it was before by deleting the "-cef-disable-gpu" parameter.

Didn't work still.

Ok, whatever the **** Steam did with their update completely screwed everything up for me as well. Same issues. I've done all the things - even the nuke option of deleting all my games and folder and reinstalling. I used to get the steam app to show up in the sys tray, but now the only thing is does is sit in the task manager and pretend to work (which it does not).

Steam has officially entered its “diva era” and refuses to run on my PC. I’ve done the adult troubleshooting routine, uninstall, reinstall, reboot, question my life choices. Nothing. Steam just sits there like, “Adorable effort. Denied.”

So I escalated.

I prayed.
I offered a blood sacrifice (fine, a paper cut, but still).
I reset my router’s chakras.
I whispered sweet nothings into my GPU.
I smudged the hard drive with sage like a tech exorcist.
I threatened the motherboard with a full Linux conversion.
I even held a séance to summon the spirit of Windows 7.

Steam remains unbothered.

And the best part? I checked online and apparently half the internet is having the same issue. New forum threads are popping up like Steam has launched a global “Let’s Not Work Today” event and forgot to tell us.

If anyone’s got a ritual stronger than what I’ve already tried, and ideally one that won’t involve law enforcement, I’m listening.
