Windows 10: Windows Installer Directory taking up around 400GB hard disk space

Hello All, I am having a Windows 11 Enterprise OS.In my c drive I've found that "windows\Installer" is occupying too much of storage.It is currently 430GB and growing.Used "TreeSizeFree" software to find this.I am having a total disk storage of 500GB and this issue is causing too much problems for me as my storage is currently having less than 500MB free space only. Please help how to clear that folder/free up my storage.

:)

 

hard disk space

Hello,

Taking into consideration that the free space is shrinking fast, it is possible that your system is creating restore points. To
delete restore points except for the recent one, simply follow the steps below:

• From the Cortana search box, type Disk Cleanup and click on the first result.
• Once the Disk Cleanup window appears, select the
  More Options tab.
• Under the System Restore and Shadow Copies column, click on the
  Clean up... button.

Once done with the steps, see if your disk space has expanded.

If you have further questions, please let us know.

Hard disk space

The first and most obvious reason you don’t have access to all your hard drive space is that there’s a significant piece of software installed on it already: your operating system. Unless you specifically selected a “no OS” model, it will come pre-installed
with something.

Another place your hard drive space might have gone is to a manufacturer-created disk partitions. In years past, a new computer commonly came with one (or a whole book full of) CDs containing software, including a recovery disk. In the event of a total meltdown
of your machine, you could boot from this drive and restore your computer to an right-out-of-the-box state.

Other possible reasons including hidden partitions, unpartitioned hard disk space, system protection takes up much space and many others. check out

Hope it is helpful.
