If you really must, use the [-no-browser +open steam://open/minigameslist](https://www.howtogeek.com/694531/how-to-reduce-steams-ram-usage-from-400-mb-to-60-mb/) trick instead. 3 | 4 | # unreact 5 | 6 | This script will download and install the last stable version of Steam before the Library update on 10-30-19 [from the Steam CDN](https://github.com/antigravities/unreact/blob/master/unreact.ps1#L73), and write a file to prevent the bootstrapper from attempting an update. 7 | 8 | Before you start, close Steam. You can also (optionally) clear out *all* of the files in your Steam directory except for steamapps and userdata. 9 | 10 | **This is intended as a temporary fix1.** Newer games, especially those that use the new Origin integration (i.e. Star Wars Jedi: The Fallen Order) may not work! More importantly, running old versions of Steam may be fine for a while... until an exploit is discovered. Be careful. 11 | 12 | ## Run this 13 | **This script runs on Windows 7 x64, Windows 8.1 x64, and Windows 10 x64.** The downloaded items will cause undefined behavior on other operating systems. 14 | 15 | ### The lazy way 16 | Open PowerShell (windows key + X -> PowerShell), and then 17 | ```powershell 18 | Set-ExecutionPolicy Bypass -Scope Process -Force; iex ((New-Object System.Net.WebClient).DownloadString('https://raw.githubusercontent.com/antigravities/unreact/master/unreact.ps1')) 19 | ``` 20 | ### The better way 21 | Download [unreact.ps1](https://raw.githubusercontent.com/antigravities/unreact/master/unreact.ps1). Then, type `Set-ExecutionPolicy Bypass -Scope Process -Force` into PowerShell, and press ENTER. After that, drag unreact.ps1 into PowerShell, and press ENTER. 22 | 23 | 1: I created this because the new update's performance was simply unbearable for me with the size of my library. 24 | -------------------------------------------------------------------------------- /unreact.ps1: -------------------------------------------------------------------------------- 1 | # https://stackoverflow.com/a/50114992/11910041 2 | function Unzip($zipfile, $outdir) { 3 | $shell = New-Object -COM Shell.Application; 4 | $zip = $shell.NameSpace($zipfile); 5 | foreach($item in $zip.Items()) { 6 | $shell.Namespace($outdir).CopyHere($item, 0x14); 7 | } 8 | } 9 | 10 | [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12 11 | 12 | echo " 13 | ########### 14 | # Unreact # 15 | ########### 16 | 17 | This script will download and install the last stable version of Steam before the Library update on 10-30-19, and write a file to prevent the bootstrapper from attempting an update. 18 | 19 | Before you start, close Steam.
