CheeseIt v1.0 Powershell Script Launcher and Cleaner

[RMarsh]

Save as .ps1 file and Run with Powershell

###############################################################################
#
# This script:
# 
# 1.) Kills processes for specified undesirable apps
# 2.) Copies the specified Key to the clipboard
# 3.) Launches the cheese EXE and waits for you to do the thing
# 4.) Removes references to previously executed programs from Registry and 
#     C:\Windows\Prefetch
# 5.) Ejects USB
#
# INSTRUCTIONS:
#    - Edit the variables below for the cheese file name, path, and keys
#    - Add any additional undesirable programs you would like killed before 
#     running cheese in the KILL section
#      (BattleNet, Steam, And Discord already included)
#    - Save file
#    - Right click, Run with Powershell
#
# !!!CAUTION:    Windows Prefetch folder requires Admin access so unless you've 
#               already opened it the cleaning command below will not work.  
#               STRONGLY RECOMMEND you disable prefetch and superfetch to avoid
#               storing files there and then there's no issue.
#    SEE HERE: https://www.thewindowsclub.com/disable-superfetch-prefetch-ssd
#
# !!!USB EJECTION:    When Windows says USB is currently in use, choose Continue
#                    and THEN press Enter to close the Powershell window.  
#                    If you close the window first, the USB WILL NOT BE EJECTED!  
#
#                    Also note that after ejection you might still see the drive
#                    letter in Windows but it's not technically mounted.

Sorry if I say it that way but this Script is.. Bad. Maybe it works, haven’t test it out but what I can see so far it is more then confusing and if there any changes in the system it would be really annoying to maintain it. Maybe if It has some structure and some functions it could be partially useful but personally I wouldn't use it in any case. You even don't say on which system nor built it was tested or coded and what are the lines for.

LOL!  It is commented throughout and if you can’t read and figure it out that’s on you.  It’s a simple little script I threw together and didn’t feel like wrapping everything up into a bunch of functions.

The only things that might need to change periodically are your key(s) or the name and path to your executable.

I made this for myself and threw it out here in case anyone else wanted to check it out.  
Again, if you can’t figure out a simple powershell script and don’t want to use it, don’t.  If you want to take it and make a version that works better for you, do it. 

Thanks for the feedback and have a great day!

Looks good and looks superior to my bat script, thx!

I'm ignorant on the subject, what's the point?
