The “Getting Windows ready, Don’t turn off your computer” message appears while Windows is installing updates. Windows will normally finish the installation process if you give it time—but, if it’s been hours, you may just need to restart your PC.
Unfortunately, it’s normal to wait a while for Windows to update, and this wastes an immense amount of time. Microsoft says there are about 700 million Windows 10 devices and that the April 2018 Update will take 10 to 30 minutes to install. So, assuming an average of 20 minutes for 700 million computers, that’s over 26,000 years of humanity’s collective time wasted waiting for Windows 10 to install a single update.
What Happens If You Restart Your PC?
The update installation process will fail if you restart your PC during this process. But how badly will it fail? Will it cause problems with your computer? To find out exactly what happens, we ran some tests.
First, we told Windows to install a standard update from Windows Update. We forcibly restarted our PC while the “Getting Windows ready. Don’t turn off your computer” message appeared on the screen. The PC restarted and we quickly saw the normal sign-in screen.
After we signed in, Windows displayed a “We couldn’t finish installing updates” notification. The update installation had failed, but Windows was still working properly. Windows will just try installing the update later.
Second, we restarted our PC while the screen said “Working on updates, 27% complete, Don’t turn off your computer.”
Windows restarted normally and we saw a message saying “We couldn’t complete the updates, Undoing changes, Don’t turn off your computer.” After the process was complete, Windows booted normally and everything worked as expected.
We also tested this process while installing a major Windows 10 update, going from the Fall Creators Update to the April 2018 Update. We rebooted our computer when the message “Configuring update for Windows 10, 10% complete, Do not turn off your computer” appeared on our screen.
After the computer restarted, we saw a simple “Please wait” message, and then the sign-in screen appeared normally. Once again, we saw the “We couldn’t finish installing updates” notification.
Finally, we tried restarting the PC when it said “Working on updates 48%, Don’t turn off your PC. This will take a while.” A “Restoring your previous version of Windows…” message appeared as Windows rolled back the update, and our PC booted and worked normally afterwards.
In every test, turning off the computer didn’t cause any problems. Windows just decided to stop updating and roll back any files that were updated. Windows does insist on re-downloading the update before trying to install it again, just in case there was a problem with the download. The updates then installed normally afterwards.
How Long Should You Wait?
Be patient and give Windows some time to finish installing updates if this message appears on your screen. Depending on how big an update Windows has to install and how slow your computer and its internal storage are, this process could take a while to complete.
It’s common for this message to appear on your screen for up to five minutes. However, if this message has appeared on your screen for a long time, you may need to restart your PC. We recommend waiting two hours, just in case Windows is doing a lot of work. Windows may just need some time to finish the process, especially if it’s a big update and your hard drive is slow and full.
If you see a percentage number on your screen and it’s increasing, leave Windows alone as long as it appears to be making progress. If the percentage appears stuck on a particular number for a long time, the update process may be stuck. However, it’s normal for Windows to appear “stuck” at a particular point for a long time before speeding through the rest of the installation process, so don’t be too impatient.
Yes, You Should Turn Off Your Computer If It Gets Stuck Here
As we’ve shown above, restarting your PC should be safe. After you reboot, Windows will stop trying to install the update, undo any changes, and go to your sign-in screen. Windows will try reinstalling the update again later, and it should hopefully work the second time. This shouldn’t be necessary, but Windows has bugs, and sometimes you have to restart your PC to fix them. This is true even when Windows is telling you not to turn off your computer.
To turn off your PC at this screen—whether it’s a desktop, laptop, tablet—just long-press the power button. Hold it down for about ten seconds. This performs a hard shut down. Wait a few seconds, and then turn your PC back on. Performing a hard shut down is never ideal, but it may be your only option in cases like this.
Warning: While we’ve successfully tested this process, there are no guarantees that your Windows operating system will work properly after you perform a hard shut down. However, if the update process is actually frozen, performing a hard shut down is the only thing you can do. We recommend always having backups of your important personal files, just in case.
How to Repair Windows If It’s Not Working Properly
Simply restarting your computer should fix the problem. However, if your PC still doesn’t start properly, you have another system problem. Restarting your computer may not have even caused the problem—your computer may have gotten stuck at the “Getting Windows ready” message because the Windows operating system already had an error.
You can often use the Startup Repair tool to fix Windows. An advanced boot options menu is supposed to appear when Windows doesn’t boot properly. Select Troubleshoot > Advanced Options > Startup Repair if you see an advanced boot options menu. If the menu doesn’t appear, you can create Windows 10 installation media, boot from it, and then select the “Repair your computer” option.
If you can boot into Windows, but it doesn’t seem to be running properly, you can also try repairing corrupted system files with the System File Checker (SFC) command instead of reinstalling Windows. You can also try running System Restore to get your operating system back to a known-good state.
If your computer doesn’t perform well even after you reinstall Windows, you probably have a hardware problem instead of a software problem.
