Deleting the system variable environment

Question

I unconsciously deleted all rows and items in the system variable environment setting in windows 11 and right now when I want to go for the Clean install of Windows 11 using installation media and click on the media creation tool in my flash memory, I face this error: "the system could not find the environment option that was entered". what should I do with this problem?

Answer 1

I couldn't run the REG file because when I want to open the System Restore Point I face the error I explained. My processor model is: AMD Ryzen 7 6800 HS with Radeon Graphics, 3201 Mhz, 8 core

Answer 2

It's because the windir environment is missing. However, you can open System Restore by running the following from Win+R Run dialog:

c:\windows\system32\rstrui.exe

Answer 3

The thing is the system restore point cannot be opened

Answer 4

The system restore point cannot be opened and I face this error: 'windows cannot find '%windir%\system32\SystemPropertiesProtection.exe'

Answer 5

Hi Hossein,

Open System Restore (rstrui.exe) and see if you have a restore point available. Let me know.

This REG file environment.reg has the default settings. It should recreate the missing variables (except the following ones):

• PROCESSOR_ARCHITECTURE
• PROCESSOR_IDENTIFIER
• PROCESSOR_LEVEL
• PROCESSOR_REVISION

Run the REG file, and post your processor model info here.
