What to do if the computer behavior gets worse after installing Windows 11?

Your machine was operating smoothly under Windows 10, but things started to go wrong after upgrading to Windows 11 on Microsoft’s advice. Be assured that you are not by yourself in this.The most frequent issues with Windows 11 are crashes and a lack of smoothness, although there is still much room for improvement. Since extremely powerful machines function flawlessly with this operating system version, they are not prevalent issues.
If you’re one of the folks who’s noticed issues with Windows 11, check out this article to learn how to fix them.
Menus
In Windows 11, Microsoft changed the arrangement of the taskbar’s components and removed Jump Lists, which has had an impact on how many users interact with the operating system. The Star11 program, which restores the Start menu and taskbar to their previous state, is the best solution to fix this problem. The software operates without a hitch, however if we install a new application, you might need to restart it to ensure compatibility, not to mention any discrepancies with some Jump Lists. However, if you want to restore Windows 10’s Start menu and taskbar, you should give Star11 a shot.
You ran out of battery

Even when the device is not in use, several of the laptops I’ve tested require more battery power with Windows 11. Because Windows 11 employs Modern Standby mode by default, which keeps the computer connected to WiFi in a low-power or sleep state, this is the case. This expedites the reactivation of Windows (just open the lid). On the other side, this function causes the laptop battery to discharge more quickly.
Making a modification to the Windows Registry to deactivate Modern Standby is required to fix this problem.
Before moving on, it’s helpful to warn the reader that this kind of change to Windows requires some understanding because we are changing settings in a delicate part of the operating system.
Before making any changes, it is strongly advised that you make a backup of your Windows Registry data. Or, if you’re unsure about your next steps, skip the adjustments suggested below. Alternately, you might entrust folks who are knowledgeable about the issue to make these changes for you.
That said, do the following:
⦁ To show the command prompt or system symbol, press Windows + S, type “cmd” in the window that appears, and then hit ENTER.
⦁ Open CMD as administrator mode.
⦁ In the open system symbol, type: REG ADD HKLM\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\F15576E8-98B7-4186-B944-EAFA664402D9 /v Attributes /t REG_DWORD /d 2 /f
⦁ Go back to typing Windows + S keys, but now type Control Panel in the command field. Select the first option that will appear on the screen.
⦁ Enter Power Options.
⦁ Click Modify Plan Settings, then Modify Advanced Power Settings.
⦁ Expand the Network Connectivity option under Standby Mode in the Balanced profile now, and turn the function off.
Empty Widget Zone
In Windows 11, there is a section called the Widgets area that shows widgets for easy access to information like news, weather, calendar, events, and other things. It may be launched by clicking on the taskbar’s lower left corner or by pressing Windows + W. Many users encounter blank Widget Zones or information that is unavailable. To fix this, click the End Session button in the Widgets area’s top right corner and sign in to this item again so that the information is presented once again.
Lack of fluidity in Windows 11

Regardless of the sort of hardware the computer has, this issue can arise even on powerful systems. In actual use, Windows 11 is sluggish and occasionally crashes. Sending and receiving emails, browsing the internet, and creating and editing documents can all be quite difficult and operate considerably more slowly than is ideal. Although the great majority of users assert that they occasionally suffer crashes, this issue might eventually become irksome and chronic. Finding a solution in this case is more difficult due to the complexity of the analysis required to determine why these crashes occur. Oddly enough, waiting for Windows 11 to continue to develop and give enhanced performance is the best course of action in this situation. Microsoft is gradually implementing updates to reduce or fix existing concerns.
It might not be the ideal option for people searching for optimal PC performance, but it will have to do for the time being (or until Microsoft fixes any lingering problems we’re not aware of).
