The Night Maria Saved the Printers
Within two minutes, users reported: “Hey, my desktop is locked down perfectly. And the ghost printers stopped!” Maria smiled. She had not only solved the crisis but also learned the most powerful control panel in Windows.
Then she went to: Computer Configuration > Administrative Templates > System > Device Installation > Device Installation Restrictions . She enabled This would block USB drives and unauthorized printers.
But she needed to stop software installs, too. She went to: User Configuration > Administrative Templates > System . She enabled and “Don’t run specified Windows applications” (adding setup.exe , installer.exe ).
She pressed Enter. A User Account Control prompt appeared. She clicked “Yes.”
The fastest way to open Group Policy Editor is Win + R → gpedit.msc . But always check you have Windows Pro/Enterprise first. And remember: with great power comes great responsibility—test your policies before rolling them out.
