PHP Code:
# This script displays a menu to run the following functions either individually or all of them sequentially.
# Each function prompts to run unless taking the ALL option.
#
# Currently the functions are : Disk Cleanup (all options) using "cleanmgr" command
# Compress OS using "compact" command
# Compress other identified directories using "compact" command
# Delete everything from "SoftwareDistribution\Downloads"
# Delete everything in "%windir%\Temp" and "%localappData%\Temp" (for current user)
# Remove all modern apps (that are possible to remove with "Remove-AppxPackage")
# DISM /online /Cleanup-Image /StartComponentCleanup /ResetBase
# Turn off System Protection
# Turn off hibernation
# Set pageFile to 200MB (minimum recommended to allow memory dumps to be produced)
# Run disk defragmentation/Trim using "defrag.exe"
# Reboot if required
#
# TODO
# 1. Update location of sdelete (or rewrite it)
# 2. The 'quiet' functionality (i.e. start the script with ./Shrink-Windows.ps1 -q) will suppress the menu and any prompts to screen.
# This is not properly implemented yet though - need to add RunOnce key to run stuff after reboot perhaps. Unsure if this is best solution
# 3. Add more stuff to temp file clearer (copy old-timer TFC?). Alternatively just drop this function.
