Windows Error Reporting Disk Cleanup handler<\/h3>\n
Having received three more such questions, I decided to work on this issue. Here is the screenshot of what Disk Cleanup displayed:<\/p>\n

Fig 1:<\/strong> Disk Cleanup showing the list of files to delete.<\/p>\n According to the above Disk Cleanup graphic, the Windows Error Reporting files constituted to 196 GB<\/b>, which is impossible in this case. I asked for the registry export of this key from the affected system:<\/p>\n The above registry location contains the list of Disk Cleanup handlers<\/a> and their registration information. When comparing the settings with my system, I noticed that a really important<\/b> value named Folder<\/strong> was missing in each of the following subkeys under the VolumeCaches<\/strong> branch:<\/p>\n |_ Windows Error Reporting Archive Files This paragraph from the MSDN documentation provides the description for the Folder<\/b> registry value:<\/p>\n A specific folder or folders to search for items matching entries in the FileList value. You can specify wildcards using the ? or * characters. If the value is of type REG_SZ, multiple folder names are separated using the | character, without spaces on either side of it. If a CSIDL value is present, only one folder can be specified in this value. The location indicated by the CSIDL value is prepended to that folder path to compose a search path. For example, see the CSIDL value description. If this value is absent, the root folder of the current volume is used. The DDEVCF_DOSUBDIRS flag is needed in that case to search the entire drive.<\/span><\/u><\/p><\/blockquote>\n Note the last line which states that the Disk Cleanup will recursively search the entire volume for the list of files mentioned in the FileList registry value (*.* wildcard used in this case) and include everything on the volume for deletion if the DDEVCF_DOSUBDIRS flag is enabled (which is enabled<\/strong> by default).<\/p>\n Available below are the REG files to fix the Folder<\/b> registry values in each of the above registry keys, which resolved the issue indeed. This is what Disk Cleanup showed after running the fix:<\/p>\n Downloads<\/b><\/p>\n RELATED:<\/strong> Disk Cleanup Bug : 3.99 TB Used by Windows Updates<\/a><\/em><\/p>\n Here is a similar case, but this time it’s the Content Index Cleaner<\/strong> Disk Cleanup handler.<\/p>\n One of our readers asked:<\/strong> I have used a registry cleaner in my PC and I have exactly the same problem as mentioned in the blog post Serious Disk Cleanup problem caused by broken registration<\/a>. The Disk Cleanup program cleaned up everything including my Windows installation. Is there a fix?<\/em><\/p>\n After comparing the VolumeCaches<\/em><\/b> branch which was sent to me by the asker, I narrowed down the issue to the following key:<\/p>\n In the above key, the value named Folder<\/strong> was missing. The Folder<\/strong> value should be present and have the following data:<\/p>\n As a result of the missing value, when you select the entry Catalog files for the Content Indexer<\/b> in Disk Cleanup, files in the current partition is erased when Disk Cleanup is run as administrator.<\/p>\n Here is a registry fix which reinstates the missing entry.<\/p>\n Copy the above lines to Notepad, and save it with a .reg extension. Right-click on the file and choose Merge<\/b>. Click Yes<\/b> when asked for confirmation.<\/p>\n The above registry setting applies to all versions of Windows, including Windows 10 (tested up to version 1809.)<\/p>\n Although I could identify where the problem was, but had no clue on how the Folders<\/b> value vanished in the first place. This may have been a result of running a registry cleaner.
