Next, select Virus & threat protection below “Protection areas. Switch to the Privacy & security tab on the left and select Windows Security on the right.ģ. Click the Start button and select Settings from the Start menu.Ģ. Here is how to scan using Windows Defender on Windows 11:ġ. You can use the built-in Windows Defender or use a reliable third-party solution to scan and remove malicious files. If a malware infection is causing the issue, you should run an antimalware scan. After the scan is complete, restart your computer to apply all changes. This will initiate a system scan which will repair corrupted system files, if any.Ĥ. In the Command Prompt window, type sfc /scannow and press enter. Right-click on Command Prompt and select ‘Run as administrator’ from the options.ģ. Open the Start menu and type ‘command prompt’ in the search box.Ģ. Here are the steps to perform an SFC scan:ġ. If the issue is related to corrupted or missing system files, you can run a System File Scan (SFC) to repair these files. Paste the Value data that you copied into this new String’s Value data.Ħ. Name it exactly as the variable whose type you want to change.ĥ. Now, right-click on the empty space, and select New->Expandable String Value. Look for the variable whose variable type you want to change and copy its Value data.Ĥ. In the Registry Editor window, navigate to this location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environmentģ. Under the Advanced tab, click the Environment Variables button.Ģ. Select Edit environment variables for your account from the search results.ģ. Open the Start menu and type ‘environment variables’ in the search box.Ģ. Here are the steps to correctly add an Environment Variable on Windows 11:ġ. This is a public forum and I do not work for Microsoft nor do I have access to any user accounts. Depending on what version of Windows you’re using, there are different ways to add environment variables in the system settings. You may have to check Hidden Items from the View tab of File Explorer as the AppData folder is usually hidden. Add Environment Variables Correctlyįirstly, make sure that you’ve added the environment variables correctly. Now that we know some of the causes of this issue let’s look at how to fix it. Fix Environment Variables Not Working in Windows 11 Malware infection: Malware infections can damage essential system files that are required for environment variables to work properly. Incorrect path added: If the incorrect path has been added to the environment variable settings, this could be causing the issue. Incorrect setup: One of the most common causes is that the user has set up their environment incorrectly.Ĭorrupted files: Another possible cause is a corrupt or missing system file, which can occur due to an incomplete installation, malware infection, or other system issues. There are several reasons why environment variables might not be working in Windows 11. Of course command-line use is only an example, it lets any program or interface access any kind of file without needing the full path.4 Final Words Why Are Environment Variables Not Working in Windows 11? For example, adding "C:\myprog\bin" to %Path% will let you just type myprog or myprog -help etc into the command-line without having to type out the full path, like "C:\myprog\bin\myprog.exe" -help. I'm not entirely sure how programs use the "Path" system variable, which is likely what cygwin was referring to, but regardless, I can assure you it has nothing to do with TMP or TEMP.ĮDIT: I just remembered what %Path% is for - it lets you access any files that are in any of the paths specified in the variable without needing to use the full path to the file. However since %Path% has no user version (by default), you can do echo %Path% and it returns the value of the system variable. AFAIK, only the "System" user can actually use those variables, as evidenced by a simple test open a cmd window and type in echo %TMP% or echo %TEMP%, and it returns the path defined in the user version of the variables. Suppose I have some programs for working in XY language, out of PATH (because I dont use them often, and dont want to litter PATH unnecessarily). The system versions link to C:\windows\TEMP. Processes started from XYplorer inherit its environment, so the ability to edit them will help tremendously from a programming perspective. %Path% is a system variable, while %TMP% and %TEMP% are both system variables as well as user variables. Windows assigns both to the same path by default to ensure consistency between different programs, and even protect against developer errors such as using both in the same program.Īlso note that the %Path% variable has nothing to do with either %TMP% or %TEMP%. As Mark mentioned, some programs use %TMP% while other use %TEMP%. They are just different aliases for the same path.
