Can you Remove Properties and Personal information in Windows Explorer?

In Windows 11, in Windows Explorer when you right click on a file and select 'Properties', you'll see that you have the option to 'Remove Properties and Personal information'.

This function can be a quick and easy way to remove some, if not all, metadata from a file. Click on the underlined, blue link and you will be given the option to create a copy with 'all possible properties' removed, or only certain properties that you select from the current file:

. . . . the function will remove the Author and reset the date created, modified, and accessed in the 'File' section, but leaves in the original dates and times in the origin section.

It may be better than nothing but it will not remove comments and track changes from a Word document even if they are hidden.

To remove the metadata from any individual MS Office file you would go to File . . . Info . . . Inspect for Issues . . . Inspect Document, and you'll get the option to run Document Inspector.

The document inspector will flag what kinds of metadata are present.

The Protect function in Adobe Acrobat includes an option to remove hidden information.

Rufus - How to create bootable media with ISO files

If you have a flash drive or disc from which you want to access a program when booting up in BIOS, the data can be saved in an .iso file - which acts as a virtual drive. The .iso image file holds the data in binary format. However you cannot download an .iso file and simply copy it to a flash drive, the standard way in Windows Explorer. To save an .iso file to a flash drive, use a free utility named Rufus, which is available here. Use the portable, or standalone version, which does not need to be installed:

[FWIW, I scanned it using Bitdefender and it was clean.] Rufus will run from the downloaded executable file and give you the option to select which flash drive you want to add an .iso image to

Rufus may take 15 minutes or more to copy an .iso file to flash drive. I used it to add the .iso file for Hiren's BootCD PE to the flash drive - it downloads from the site as a single file, 'HBCD_PE_x64.iso'. [Hiren's includes several data recovery tools, and I needed to use it to check if the drive of an old laptop I was decommissioning had been successfully wiped.].

It will take Rufus longer than an hour to add a 3 GB file to a flash drive.

When the Hiren Boot .iso file is added, you will see multiple files and folders.

I inserted the flash drive into the laptop that I wiped, and pressed F12 [the laptop was a Toshiba - other hardware may require another function key] to enter BIOS - the firmware. The flash drive was recognized:

The Windows 'Remove Everything' option to wipe a hard drive

As discussed here before, even after files are removed from the Windows Recycle Bin, and even after a drive is reformatted, it's still possible to recover deleted files with widely available tools. See the Tip of the Night for December 29, 2019.

Windows 10 and Windows 11 include a reset option which can help wipe the drive of your PC, overwrite the existing data with new data, but this method may not be completely effective. Under Settings if you go to System . . . Recovery, you will see an option to 'Reset this PC'.

. . .if you then choose the option to 'Remove everything', that will initiate the process of wiping the hard drive.

However, there are some reports that even after the 'Remove everything' option has been run, files can still be recovered. See this April 2023 report by Tom's Hardware, detailing the subsequent recovery of persumably wiped files with EaseUS Data Recovery.

A better, or supplementary, option may be to use a secure erase option in the BIOS firmware that manages a computer at the most basic level without the operating system. You can enter BIOS by pressing F2 when rebooting on most kinds of PC (use F10 if you have a HP computer and F1 for a Lenovo device). Or, search for 'advanced startup options' in Windows

. . . and then select the option to 'Restart now'

When your PC restarts you should then be given the option to go into Troubleshoot mode and then under advanced options select the firmware settings.

The Dell BIOS firmware includes an option to wipe the device.
