The Windows registry is a hierarchical database that stores configuration settings and options for the Windows operating system and the applications that run on it. Over time, the registry can become large and cluttered, which can lead to performance problems. Therefore, it is sometimes useful to check the size of the registry to see if it needs to be cleaned up.
There are a few different ways to check the size of the registry. One way is to use the Registry Editor. To do this, open the Registry Editor by pressing the Windows key + R and typing “regedit” into the Run dialog box. Once the Registry Editor is open, click on the “File” menu and then click on “Export.” In the “Export Registry File” dialog box, select a location to save the registry file and then click on the “Save” button. Once the registry file has been saved, you can open it in a text editor and then search for the string “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\hivelist.” The size of the registry is listed next to this string.
