Windows 8.1 Installer Folder Cleanup

On my Windows 8.1 laptop with a small SSD (100GB), disk space was running out. When I checked disk usage by folder using TreeSize, I found that C:\Windows\Installer was taking up over 22GB! A quick online research revealed that I couldn’t delete files from this folder safely. However, I also learned that it could be holding files that were no longer in use or needed.

On further search, I found this neat little utility called Patch Cleaner, which looks for such unused files and gives you the option to delete them or back them up to another location. When I ran it, I found that about 15GB out of those 22 were being hogged by the files that were no longer needed! All of these 400+ unused files are MSP files. I have moved these files to an external hard disk just in case there is an issue later. Restoring the files is as easy as copying them back to the installer folder.

Thank you Patch Cleaner for freeing up over 15% of my disk space!


Windows update broke Cisco AnyConnect Mobility VPN Client

This morning Windows prompted me to reboot to apply updates. After I did that, the Cisco VPN client started reporting “Failed to initialize connection subsystem.” When I looked up, I found this article – Microsoft’s SSL 3.0 Poodle-busting patch KB 3023607 breaks popular Cisco VPN client

I followed the compatibility route suggested as a workaround in that post, and it fixed the problem for me:

  1. I closed the Cisco AnyConnect Window and the taskbar icon
  2. Right-clicked vpnui.exe in the Cisco AnyConnect Secure Mobility Client folder. (I have it in C:\Program Files (x86)\Cisco\Cisco AnyConnect Secure Mobility Client\.)
  3. Clicked the Troubleshoot Compatibility option
  4. Chose Try Recommended Settings.
  5. The wizard suggested Windows 7 compatibility.
  6. Clicked Test Program. This will opened the program. I entered the credentials and connected.
  7. Closed the dialog.
