This post was intended to be a reply to "Hard drive nearly full for no apparent reason" but has ended up as a separate thread.
I seem to have a similar issue. I've discovered that my Windows\Installer folder is over 29GB. Nearly all of the space is used by about 3000 .msp files that have nine distinct dates beginning 10/8/2008 and ending 12/9/2009. On 8 of the dates all the files are identical in size. One one of the dates there are files of two different sizes. 12/9 is around when I first noticed space problems on the drive and began working on it. Deleting logs, compressing unused files, has kept space available until now. Because the Installer folder is hidden I didn't notice it size until yesterday
There are no recent install failures in Windows update and I can't determine what app these files are associated with. The Summary tab for every one that I've checked shows only the keyword PatchSourceList. The machine is a server so it does not have Office installed. It is running Windows Server Update Services but those files are being stored on a separate drive.
I've run Malwarebytes and it found one item which I allowed it to delete. The log entry is: Registry Data Items Infected:
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Start_ShowMyDocs (Hijack.StartMenu) -> Bad: (0) Good: (1) -> Quarantined and deleted successfully.
I may be wrong but this appears unrelated.
Any suggestions?
