+## Windows Installation
+
+To install GoodKey on Windows, download the installation file from the official
+hub and follow the on-screen instructions.
+
+## Important Note for Windows Users
+
+In some cases, you may encounter a critical error warning after system startup,
+leading to a system restart. This issue may be related to the `gkcertsvc.dll`
+component. To resolve this, you can disable the certificate provider by running
+the following command in an administrator terminal:
+
+```
+regsvr32.exe /u gkcertsvc.dll
+```
+
+Please note that this should only be done if you are experiencing the
+aforementioned issue, as it may affect other functionalities of the GoodKey
+software.
