Dare to move? Make a boot key U disk in 2 minutes!

Is it true that many friends don't like others to use their own computers? After all, they have their own privacy, and more importantly, they are afraid of being deleted or destroyed by mistake. The editor will share with you a method to prevent others from using your computer with just a USB flash drive. Who dares to do so?

First insert the USB flash drive, remember the drive letter displayed on the computer by the USB flash drive, for example, this is the F drive, and then click to enter.

At this time, at the head of the manager column, click to switch the tab to "View", and check "File Extension".

Then right-click "New-Text Document" in the F drive letter folder.

Note that the input file name is key.txt at this time, where .txt is the automatically provided notepad file format, then modify txt, change it to sys and press Enter to confirm, and select "Yes" in the prompt dialog box. Then take a look to confirm whether it is the Key.sys of the F drive.

Restart a notepad (you can find it by entering notepad in the start menu) to create a new document, and enter if not exist F:key.sys shutdown -s -t 20 -c. Simply put, check that if there is no Key.sys file in the F drive, the system will automatically shut down after 20 seconds. After confirming, click "File-Save As".

Select the C drive, then change the save type to "all files" and name it "start.bat" in which the word "start" can be replaced at will, but the following .bat should be consistent with the editor's.

Click the start menu again and enter "group policy" to start the group policy editor.

In the tree list on the left, select "Computer Configuration-Windows Settings-Script (Startup/Shutdown)", and then double-click "Startup" in the right column.

Here comes the most important place, click "Add" and then click "Browse" to select the newly created "Start.bat" in the C drive, and click OK to take effect.

In this way, the system will first load the executable command "start.bat" of the C drive when it starts, and the "start.bat" will check whether there is the Key.sys file of the F drive according to the commands inside, and if it is normal Start, if not, then it will shut down within 20 seconds-then others will not be able to start your computer.
