Cleanup Windows 10 Powershell script
##
## Windows 10 cleanup script.
## Remove dodgy tracking settings, unneeded services, all apps, and optional features that come with Windows 10. Make it more like Windows 7.
## NOTE: this was tested on Creators Update (1703) and Fall Creators Update (1709). Some of this may not work as expected on newer versions.
##
## Instructions
## 1. Run this script (under Powershell as Administrator):
## powershell -ExectionPolicy Bypass .\cleanup-win10.ps1
## 2. Let it run through, you may see a few errors, this is normal
## 3. Reboot

Creates a bunch of pages in SilverStripe for testing. It'll take a long time to run, but good for testing how your site performs with a huge amount of pages. Put it into your `mysite/tasks` directory, then invoke the script by running `sake dev/tasks/GeneratePagesTask flush=1`
<?php
class GeneratePagesTask extends BuildTask {
public function run($request) {
for($i = 1; $i < 10; $i++) {
$segment = sprintf('page-top-level-%d', $i);
$p1 = SiteTree::get_by_link($segment);
if(!($p1 && $p1->exists())) {
echo "Creating page $i...";
