This article shows the difference between Upgrade Warnings & Upgrade Blocks and tells you how to go about resolving them, should you encounter any of them, while upgrading to Windows 7/8/10.
Windows Upgrade Warnings vs. Upgrade Blocks
When upgrading to Windows, the Setup performs compatibility checks. If it discovers any issues which may affect the smooth upgrade process, they will be noted in the Compatibility Report.
For your reference, this file gets saved to your desktop as Windows Compatibility Report.htm.
When the compatibility report identifies any issue which will seriously affect the upgrade process and maybe even result in an undesirable outcome, it will give out an Upgrade Warning message.
This indicates that the upgrade can continue, but with some undesirable impact to your configuration.
If the warning relates to some Windows feature, the message would appear as follows:
Upgrading Windows will affect the following features
And the features may then be listed.
In such a case it might be a good idea to turn off the specified Windows Features before proceeding further. Cancel the upgrade, open Control Panel, and Turn Windows features on or off. These Windows features would in all probability not work properly after the upgrade.
If the warning relates to hardware or software compatibility issues, the message would appear as follows:
Upgrading Windows will affect the following devices and programs
In case it relates to a hardware issue, Cancel the upgrade, open Control Panel, and search for “update device drivers”, or go to the device manufacturer’s website to search for updated drivers.
In case it relates to a software program issue, cancel the upgrade and uninstall the program first.
Upgrade Warnings are thus messages which indicate a potentially undesirable outcome, but will not prevent Setup from performing the upgrade.
On the other hand, Upgrade Block messages indicate that the upgrade cannot be performed.
In order to upgrade Windows, you must first resolve the issues identified in the report.
The block message would typically appear as follows:
The following issues are preventing Windows from upgrading.
And the issues may be mentioned.
In such a case, cancel the upgrade, complete the tasks mentioned in the reports, and then restart the upgrade.
Once you complete the required actions, the upgrade should be able to complete successfully.
