Windows Anytime Upgrade is a method provided in Windows 7 & Vista, for upgrading from one Windows edition to a higher edition. While the WAU procedure in Windows Vista involved a setup.exe, the process in Windows 7 is different, as it uses the Windows servicing infrastructure to perform the process. Driver, data, and application migration issues are completely bypassed.
Windows Anytime Upgrade
If you want to upgrade Vista to Windows 7, Windows Anytime Upgrade will really make your job easy! To do a WAU, you need to open the Windows AnyTime Upgrade module via the Control Panel and enter the new key and finally re-activate Windows.
Windows 7 will automatically upgrade to a higher edition provided it is a valid Upgrade Path.
All the files & components required for upgrading to a higher edition of Windows 7 are already installed on the computer when you install Windows, and are located in the Windows\Winsxs & Windows\servicing\packages folders.
Now in a rare eventuality, your Windows Anytime Upgrade may not go through smoothly and you may receive the following error message/s:
Windows Anytime Upgrade was not successful
The upgrade was not successful. Please try the upgrade again
Here are a few troubleshooting steps you may want to try:
1. Restart the computer to complete pending operations, if any.
2. See the following log files. the log entries may give you any idea why the WAU failed.
- %userprofile%\AppData \Local\Microsoft\Windows \Windows Anytime Upgrade\upgrade.log
- %userprofile%\AppData\ Local\Microsoft\Windows \Windows Anytime Upgrade\upgrade_dism.log
- %systemroot%\Logs\CBS\CBS.log file
- %systemroot%\Logs \CBS\CBS.persist.log file
3. Run Chkdsk and see if it helps.
4. Run Memory Diagnostics to check for issues with the system hardware. Type Memory in start search and hit Enter to open Open Memory Diagnostics Tool. Click Restart Now and Check Problems. Your computer will restart & the diagnostic program will start. Please note any reported errors.
4. Run CheckSUR to resolve problems with the component store.
5. If your key is invalid and you need to change the keys you may have to open regedit and deleting the ProductKey value in the following registry key first:
HKCU\Software\Microsoft\Windows\CurrentVersion\WindowsAnytimeUpgrade
6. This problem can also occur if Windows 7 SP1 (KB976932) has been downloaded by Windows Update but has not been installed yet. In such a case, to resolve this issue, you may want to follow the steps mentioned in KB2660811.
Hope something helps.

Microsoft Product keys are sensitive case, Because Microsoft provide it for only one system at the same time, I was need the windows 7 key for my laptop to upgrade from home premium to professional, So I contact to Microsoft but they denied to give me a key, So I search all over the world to purchase it.
Recently, I ordered at a site from Ind-pak, They provided me 3 windows 7 pro key sticker and 2 windows 8.1 pro keys, Which is legal and working good. I’m happy after getting so cheap license.
You can also get an unused Windows 7(any version)8, 8.1 pro License key from: ODosta Store
I want to buy another, But Now Please tell me, If can I use my windows 8.1 professional product key at my existing windows 8.1 standard KMS Activated License, being upgrade it.
