Hi, There
As I known, it looks like Windows didn’t properly recognize your admin account, so even as a global admin, you can’t install apps. Here’s a quick fix:
- Check account type: Press Windows + R, type
control userpasswords2, hit Enter, make sure your account says Administrator. - Enable built-in Admin: Open Terminal (Admin) and run:
net user administrator /active:yes
Log in as Administrator to regain full permissions.
- Fix your account: Go to Settings > Accounts > Family & other users, select your account, and set it to Administrator.
- Offline Reset if needed: Restart with Shift + Restart > Troubleshoot > Reset this PC. Choose to keep files or remove everything, Windows uses the recovery partition, no download needed.
