It goes back to the days of CP/M

Temporary Folders are used by almost every program on a computer, either during the installation of a program, or for the operation of the app/program.

These are the default values of some of the more important Temporary Folders.

Temporary Internet Files:

Please see:

Redirecting

Start Internet Explorer.

On the Tools menu, click Internet Options.

On the General tab, click Settings.

Click Move Folder. [move only if not set to default, or you need to move to another drive]

Click the folder you created in Step 1.

Click OK, click OK, and then click OK again.

Restart your computer

and

Redirecting

• 
  Open Internet Explorer.
  

• Click on the Gear icon, and select Internet Options.
• On the General tab, under Browsing History, go to Settings.
• On the Temporary Internet Files tab, click on Move folder. [move only if not set to default, or you need to move to another drive]

Default location is -

C:\Users\[UserName]\AppData\Local\Microsoft\Windows\INetCache\

i.e.->C:\Users\JoeCool\AppData\Local\Microsoft\Windows\INetCache\

See:

TEMP-The temporary folder on the computer. A typical path is %USERPROFILE%\AppData\Local\Temp.

TMP-The temporary folder on the computer. A typical path is %USERPROFILE%\AppData\Local\Temp.

To check your values -> in Cortana type 'Advanced System Settings' (click on the best matched results)- Advanced Tab - Click 'Environmental Variables' button - make sure your TEMP and TMP show the variables above.

After changing the 'Environmental Variables' (Rarely necessary)->Reboot.

Run a Disk Cleanup with all the boxes checked in the final dialog box. (a good process to run occasionally, even if you are not making changes in 'Environmental Variables').

How to recover Environmental Variables that were deleted

To clarify, I deleted everything from the path/environmental variables settings.. i know that was a huge mistake but i've been having BSOD errors and i thought maybe this would solve it.

I am unable to perform the clean boot due to not being able to access system configuration. It's as if it's gone. Same applies to command prompt, powershell, task manager, event viewer + other apps. Their icons have all disappeared and when I try to search for them, they appear in the search with a generic icon on the list but an error pops up upon clicking.

I tried the second method using command prompt in safe mode. The desktop doesn't load in the admin profile, just black screen but strangely enough, the command prompt works.
