Open File Explorer by clicking it on the taskbar or using Win+Ethe shortcut.
Once it opens, click on the three dots at the top and then on Settings.
Click the "Open Explorer in" drop-down menu and select "Home" in the Folder Options dialog box that appears.
Click Apply and then OK before closing and reopening File Explorer. Your Quick Access menu should be back.
Note: If you are an enterprise user, you will see a "Recommended cayman islands telegram data Section" in the Options dialog box. You will need to uncheck it and disable it to get the quick access menu back in this case.
Now you need to clear the Explorer history, as crashes can sometimes prevent the quick access menu from appearing. Open the Options dialog box in Explorer and click the Clear button.
Then simply re-pin the missing items to the quick access menu to get them back. Find the item you want to pin and right-click it before clicking “Pin to Quick Access.” It will now be visible in the quick access menu.
Finally, you need to turn the Recent Files option back on. Click on the three dots at the top and then click on Options again. Then click on the checkbox next to Show Recently Used Files to turn it on before clicking OK.
