How to download and install the August 2024 security updates
Security updates are installed automatically on most home Windows devices. This does not happen immediately though. Administrators may force updates right after they are released. This is done in the following way:
- Select Start, type Windows Update and load the Windows Update item that is displayed.
- Select check for updates to run a manual check for updates.
Windows Update should display the security update and start to download it.
Note: we recommend that you create a full system backup before installing any Windows update. This gives you another restoration option should things go wrong. The free Paragon Backup is a good choice, but there are others.

I guess my “Pause” setting expired, so all the updates installed on Windows 11 without any trouble. Windows 10 worked fine as well–but, one update from some point in time–maybe one month ago–slowed Windows 10 to a crawl with a number of UI issues; then, the rest of August’s were installed, rebooted, and now the system is speedier than it has been in months.
Fortunate!
Yes, there are individuals out there that only have a limited number of devices to updates. I have1,000s of PC and servers to update so we use Windows and despite the occasional issues Windows is a solid OS. If I rolled out a different OS for thousands of users, I would be fired within the hour. ghacks many thanks for you site it is much appreciated.

From AskWoody …. sadly KB5042320 still fails with Error 0x80070643… 250 MB Free Win RE Recovery space still requd as with 5034441 …. Apparently the Same Pig, different lipstick = No Fix ….
Ditch Windows and switch to Linux Mint. It just works and the updates are painless.
Microsoft and Windows are a travesty!!!
Mint is the best i’ve used as a replacement for Windows. Ubuntu is my second pick.
Never had any update problems with linux distros.
BTW, yesterday updated 1 notebook from Mint 21.3 to 22.
Works, but not recommended if you also have progs installed from outside the repositories (so I had).
Many of them have to be uninstalled because their libraries may not be compatible with v22. Also true: several programs do not (yet) install in v22. Waiting for updates from prog or Mint…
Not an essential notebook, but troublesome.
Microsoft Issues Patches for 90 Flaws, Including 10 Critical Zero-Days don’t do it
you will have to refomat your pc i did and the update stops and the windows sign and stops and does not go any where you can turn off your pc 100’s of times and it does not good at all
As usual, I’ll delay the installation (on Win 10, click on settings – update & secuity – pause updates for 7 days) to let the rest of MS’s userbase debug these before I install them myself.
i can tell you now do not do this if you don’t want to have refomat your pc again on 8/13/2024
Windows Update and Bitlocker, what can go wrong?
