This was made almost a year ago, so don't expect everything to work fully, I recommend checking out Steam-Debloat
Yeah it looks promising and I'll look into it. For now, NoSteamWebHelper has been working quite well. Thanks for the code, I'll check it out!
update: new script to always launch steam in SmallMode
- reduced ram usage when idle, it's rather lazy (after 15minutes is now 127.9MB on win11)
- like the old version it adds a
Steam_mindesktop shortcut + updates startup entry if set - using only supported steam launch options and cfg edit, no more ifeo hijacking
- should not require admin rights, but if it does not work run it once as Admin
the project I talked about that patched the steamui dynamically was more efficient but less reliable
have been using this script instead and everything works normally
I can switch back to Large Mode when needed, and when I start Steam_min next time it is back in Small Mode!
update: made it fully hybrid i.e. can enter raw code into terminal/powershell directly for installation
Shouldn't you be defining $sharedconfig = $true and $localconfig = $true within the loops so the first time it hits a file that switches it to $false it still works?
Here's what I came up with, uses -pv and gets rid of the need for StringBuilders by streaming directly to a variables and joining resulting arrays:
dir "$STEAM\userdata\*\7\remote\sharedconfig.vdf" -pv vdf |foreach {
$sharedconfig = $true; $t = gc $vdf |foreach {
if ($_ -match '\s+"SteamDefaultDialog"\s+"') {
if ($_ -match '#app_games') { $sharedconfig = $false }
"`t`t`t`t""SteamDefaultDialog""`t`t""#app_games"""
} else { if ($sharedconfig) { $_ } } }
if ($sharedconfig) { set-content $vdf ($t-join"`n") -nonew -force -ea 0; " $vdf" }
}$re = '\s+"(LibraryLowBandwidthMode|LibraryLowPerfMode|LibraryDisableCommunityContent|LibraryDisplayIconInGameList)"\s+"'
dir "$STEAM\userdata\*\config\localconfig.vdf" -pv vdf |foreach {
$localconfig = $true; $t = gc $vdf |foreach { if ($_ -notmatch $re) {
if ($_ -match '\s+"SmallMode"\s+"') {
if ($_ -match '"1"') { $localconfig = $false }
"`t`t`t`t""SmallMode""`t`t""1""`n$_"
} elseif ($localconfig -and $_ -match '\s+"LastPlayedTimesSyncTime"\s+"') {
"`t`t`t`t""SmallMode""`t`t""1""`n$_"
} elseif ($localconfig -and $_ -match '\s+"FavoriteServersLastUpdateTime"\s+"') {
"`t""LibraryDisableCommunityContent""`t`t""1""`n`t""LibraryDisplayIconInGameList""`t`t""0""`n$_"
"`t""LibraryLowBandwidthMode""`t`t""1""`n`t""LibraryLowPerfMode""`t`t""1""`n$_"
} else { if ($localconfig) { $_ } } }}
if ($localconfig) { set-content $vdf ($t-join"`n") -nonew -force -ea 0; " $vdf" }
}Also got rid of using sc for set-content since that alias is removed in PowerShell 7 due to conflicting with sc.exe
Oh, and I escaped the quotation marks by doubling them instead of doing `" since that makes it a bit more readable.
AveYo, you are a lifesaver! This goddamned web "helper" was devouring my network activity and memory, and this is the first fix that has actually worked. thank you very kindly.
@God-damnit-all thank you very much for your feedback!
I actually planned an update to the script, and made it to work in PS 7 just for you!
added a switch that makes it more readable, still using sb for compatibility with PS 2.0
and it's not like one has thousands of active accounts on a tape drive to matter ;)
@Derbear2112 glad to help!
I have updated the script, further changes will probably happen here:
updated for latest steam
