After installing an update for Outlook, I’m encountering some strange issues with Outlook which I think are directly related to the update and not to any other Outlook issue.

How can I uninstall the update again to verify if the issue will indeed be gone then?

While in general updates should improve Outlook, updates such as KB2509470 and before that KB2412171 (coincidentally both for Outlook 2007) both got pulled and it was recommended to uninstall them if you were seriously affected by it.

Free .pat files for revit. There are several ways to do this depending on the type of update, your version of Outlook and your version of Windows.

Note: If you are using an Office 365 installation such as Office 365 Home/Personal, Office 365 for Business, Office 2016 Home and Business or Office 2019, see the instructions at Uninstall Office 365 Click-To-Run Updates instead.

Security update, regular update, rollup update, Service Pack or hotfix

Just a word of caution; if the update you are trying to uninstall is an update that fixes a security issue, then it is highly recommended to leave the update installed and see if there is a workaround available for the issue you are experiencing with the update.

If there is no workaround, read the security bulletin for the update to verify if you are affected by this security flaw and/or if there are other ways to protect you from this. If there is, you can safely remove it if you take those measurements.

Service Packs can be safely removed as long as the previous Service Pack or original release is still supported (as Service Packs also contain security updates). Other non-security updates can be safely removed as well.

Note: When a fixed version of a security update is being released, make sure you install it again as soon as possible.

Method 1: Standard uninstall method

The recommended method is to remove the update Control Panel. Most updates can be removed this way.

Windows 7
Start-> Control Panel-> Uninstall a Program-> View installed updates
Windows 8
Right click on the Start Menu button-> Control Panel-> Uninstall a Program-> View installed updates
Windows 10
Start-> type; Control Panel-> Uninstall a Program-> View installed updates

The overview is sorted by “Installed on” by default which should help locating the update. You can also type “KB” and the number in the search field in the top right corner to easily locate the update.
For instance; KB2509470
Once found, select the update and press the “Uninstall” button.

Method 2: System Restore

Some updates cannot be removed via the “Installed updates” list. In that case you can use System Restore to revert your system back to a date before you installed the update. This will uninstall other updates or applications that you have installed between then and now as well so make sure you reinstall those afterwards.

Note: Using System Restore does not affect your data but it never hurts to make a backup of your Outlook data before proceeding.

You can start System Restore in the following way;

Windows 7
Start-> All Programs-> Accessories-> System Tools-> System Restore
or
Start-> type: System Restore
Windows 8 and Windows 10
Start-> type: Create a Restore Point
System Properties will open to the System Protection tab where you can click the System Restore… button.

Method 3: Reinstall Office

If the update cannot be uninstalled and you have System Restore disabled or no restore point from before you installed the update, then you’ll have to reinstall Office. This sounds more drastic than it is; it basically is only time-consuming.

Before you start, make sure you have the installation file/CD/DVD for your version of Office and your Product Key available. If you have misplaced them see; Office replacement installation disks and keys.

Note: While reinstalling Office will not delete any settings or data, it never hurts to make a backup of your Outlook data before proceeding.

After you have reinstalled Office, make sure you reinstall the latest Service Packs and updates for Office again (except of course the one that was bugging you).

Block update from being automatically installed

When you have uninstalled an update which has not yet been pulled by Microsoft, it will be automatically installed again if Windows Update is configured to automatically install updates. There are 2 methods to prevent this from happening;
