％USERNAME％变量选择了错误的用户名

Question

Some login problem came with my previous user account. Therefore, the Admin created a new User account for me in the same PC.

PROBLEM: Now I have to write a common script (which will be used in other PCs too). In this script I have to specify the path of Desktop . I am using the following command (only example here) line which works everywhere except my PC

cd "C:\Users\%USERNAME%\Desktop"
pause 

It is not working in my PC because it is assigning the old username to the %USERNAME% variable and therefore trying to enter the Desktop of previous username which does not exist anymore (I removed the old user folder).

How can I get the correct user name (new user name) assigned to the %USERNAME% variable?

Answer 1

You can retrieve the folder configured as Desktop for the current user from the registry

@echo off
    setlocal enableextensions disabledelayedexpansion

    for /f "tokens=2,*" %%a in ('
        reg query "HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders" /v desktop
        ^| find "REG_"
    ') do call set "desktopFolder=%%b"

    echo %desktopFolder%

Note that as by default the registry key requested is of REG_EXPAND_SZ type, it can contain environment variables references that need to be expanded. That is the reason for the call set and not a direct set , we need to force a second parse of the retrieved value to get a full expanded folder path.
