Last month, I bought a gaming computer set from my local Advice Store here in Surin. During the purchase, I opted to have them move the 512 GB M.2 from the 1st slot to the 2nd slot and install a new Corsair 1 TB M.2 with heatsink in the 1st slot. After this was done they would installed Windows 10 on the main SSD. When I set-up the system at home, I deleted a few applications I didn't want and updated Windows 10 to 11. The update was successful with one minor issue. In the lower right corner there was a notification that a Windows key was not found. Checking the security center it stated "some features of Windows were not available without a product key". After 2 days of looking at the notification in the corner of the screen, I decided to research for a solution.
The first thing I did was Google "cheap windows 11 keys". At the top of the search page was the webpage AllKeysShop. com. I went to that site and it had a list of 10 websites to choose from with star ratins and prices. I chose Wincdkeys and clicking on the link took me to their webpage. I selected Windows 11 Pro retail version and added to cart, then applied the 75% discount from the AllKeysShop site. I checked out with my Bangkok Bank debit card. Recieve a SMS from BB for 49.88 baht. I received an email from Wincdkeys within seconds and followed the instructions to redeem the code. After entering the MS product key as directed it was accepted immediately. After reboot the message in the corner was gone. Success! I hope my experience will be of help to others looking for legitimate Windows product keys.
