However there is a small trick that allows you to reset the rearm count back to 4. To do this you need delete the registry key which contains the Last Rearm Time, however this key can not be deleted or modified during a normal user session. To delete the key you will need to run the following commands in the windows recovery console.<\/p>\r\n\r\n\r\n\r\n<pre class=\"wp-block-preformatted\">reg load HKLM\\MY_SYSTEM \"%~dp0Windows\\System32\\config\\system\"\r\nreg delete HKLM\\MY_SYSTEM\\WPA \/f\r\nreg unload HKLM\\MY_SYSTEM<\/pre>\r\n\r\n\r\n\r\n<p>To do this save the above commands to a .bat file \u2018reset.bat\u2019 to the C:\\ root folder. Restart your computer, pressing <strong>F8<\/strong> to get to the Advanced Boot Options. Select the option to <strong>Repair Your Computer<\/strong>. Select your keyboard input method. Login with your login details. In the System Recovery Options menu, select <strong>Command Prompt<\/strong>. Now type in <strong>C:\\reset.bat<\/strong>. (If it says \u201c\u2018C:\\reset.bat\u2019 is not a recognised as in internal or external command\u201d message, then it may be because the \u00a0C Drive\u00a0is bring used as a recovery partition. Try again using D:\\reset.bat) If successfully you should get the message \u201cThe operation completed successfully\u201d. Next reboot your machines.<\/p>\r\n\r\n\r\n\r\n<p>After rebooting you may get a message stating that this product is not genuine. This can be ignored. Running slmgr \/dlv again will confirm that the rearm count has been increased again, thereby giving you another 120 days worth of windows use.<\/p>\r\n\r\n\r\n\r\n<figure class=\"wp-block-image\"><a href=\"https:\/\/www.emperial.dk\/wp-content\/uploads\/2019\/04\/slmgr-rearm-count-4.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-full wp-image-412\" src=\"https:\/\/www.emperial.dk\/wp-content\/uploads\/2019\/04\/slmgr-rearm-count-4.png\" alt=\"\" width=\"468\" height=\"409\" srcset=\"https:\/\/www.emperial.dk\/wp-content\/uploads\/2019\/04\/slmgr-rearm-count-4.png 468w, https:\/\/www.emperial.dk\/wp-content\/uploads\/2019\/04\/slmgr-rearm-count-4-300x262.png 300w, https:\/\/www.emperial.dk\/wp-content\/uploads\/2019\/04\/slmgr-rearm-count-4-343x300.png 343w\" sizes=\"auto, (max-width: 468px) 100vw, 468px\" \/><\/a><\/figure>\r\n","protected":false},"excerpt":{"rendered":"<p>&nbsp; &nbsp; An install of Windows 7 without an activation key allows for 30 days of usage.
