Valve has released a big update to its online store and distribution platform Steam. Among typical bugs fixing and making the user experience a little more fluid, we have received some major updates as well. Please take note that you need to update Steam itself to the latest version in order to get new features.

Storage management Page update

The storage management page has received a complete redesign and UX overhaul and it is now much easier to manage your game libraries and create new ones. The page itself looks and feels a little console more like but thanks to that it offers a much easier and clearer look and feel. Another thing with the Steam store management page is the ability to move installation files from one location to another. Let’s say that you have two or more hard disk drivers in your machine and that you have SSD that you use for running stuff since it is fast and larger and slower one for storage. Now you can easily and quickly move one installation from one to another in order to take advantage of your faster SSD for quicker LOAD game times without making a new installation.

Steam Download page improvements

The download page has also received some love from Valve by enabling us to now see the installation progress. So far on the download page of Steam, you would only get download progress but it has been updated to show installation progress after download as well now making it more straightforward and giving you a general idea of how much more time there is to wait in order to start gaming. Also, you can now drag and drop items in the download bracket to reorder download orders or place them as active downloads to start downloading right away.

Recent Windows updates have been slowly but surely moved a lot of control panel features into settings. This indicates that in the long term goal is probably to get rid of the control panel altogether. No matter how the setting app is easy to use and good there are still things in the control panel that we need and we will still need until they are all moved in the setting application. There are several ways to open and get to the control panel from run dialog to shortcut keys but one perhaps more convenient and easiest way is to just simply have in file explorer right beside hard drives double click away. In order to place the control panel icon inside file explorer, we will need the help of our old friend: the registry editor. As always playing with the registry editor can cause some instability and it is always a smart thing to back up it first before attempting any kind of edits.

Registry editor adding a key

To open registry editor press ⊞ WINDOWS + R to open the run dialog and inside type in REGEDIT followed by ENTER Once the registry editor is opened locate the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\MyComputer Right-click on the NameSpace folder on the left navigation pane and then select New > Key Rename the key with {21EC2020-3AEA-1069-A2DD-08002B30309D} (This CLSID code will add access to the Category view of the Windows 10 Control Panel) or with {26EE0668-A00A-44D7-9371-BEB064C98683} (This CLSID code will add access to the large icons view of the Windows 10 Control Panel) Save and exit the registry editor Now when opened, file explorer will show a control panel icon for easy access.

Error 0x8000ffff prevents you from using the Microsoft store. Altho it is not a critical error that will break Windows, it is annoying enough that will require fixing so we can use the store once again and install apps when we want to. Interesting thing is that this error was present inside Windows 10 as well causing some annoyance, you think Microsoft would learn, and then you see reality. Anyway, we have not come here to bash Microsoft, we came to solve errors. So there are several problems that can cause this error like issues with accessing the Microsoft servers, corrupt system files, settings being misconfigured, malware infections, or conflicting applications. We will cover all solutions for each scenario taking approaches from most simple solutions to more complex ones. Follow the guide and let's fix this annoyance.

Wait for Microsoft's servers to become accessible

Yes, just wait. If the problem is tied to Microsoft servers having heavy load or being temporarily down there is not much you can do except for their tech team to resolve the issue. Go to Twitter or Facebook and check the Microsoft page to see if anyone else has this issue, if several people are reporting the same error then it is due to server problems. In this case, the only thing you can do is to wait.

Run troubleshooter

If servers are working fine then the issue is within your system so let's get down to fixing. Most simple and easiest solution is to let Windows try and resolve the problem by itself. We will use troubleshooter for this, Windows's integrated fixing solution: Press ⊞ WINDOWS + I to open the settings app Click on System in the left panel, then on Troubleshoot on the right Click on Other troubleshooters In most Frequent section find Windows Update and click on the Run button Wait for the troubleshooter to finish and follow on-screen instructions

Clear Store cache

If the troubleshooter has not found the issue or was unable to repair it, the next step is cleaning the Microsoft store cache in order to eliminate corrupted or partial cache files. Press ⊞ WINDOWS + R to open the run dialog In run dialog type in: wsreset and press OK or press ENTER A black screen will appear and it will not give any kind of feedback about progress, so it might seem like Windows has frozen, but do not panic nor try to do anything, this kind of behavior is normal, just wait for the process to finish and once it is done Microsoft store will launch with the cleared cache.

Disable Proxy

Proxy setting can interfere with establishing a connection to the store servers and if previous solutions have not worked we will check proxy next. Press ⊞ WINDOWS + R to open the run dialog Inside run dialog type: inetcpl.cpl and hit ENTER or press OK button Inside Internet Properties click on the Connections tab and then on LAN settings Uncheck the box next to Use a proxy server for your LAN and click on OK

Turn off antivirus

If nothing worked so far, turn off your anti-virus software, there is a slight possibility that your antivirus is misconfigured or preventing the system from accessing the store. Turn off antivirus and firewall to make sure that this is not an issue.

Delete the software distribution folder

So, we have tried a lot of things, and the error still persists? Let's then go to the next step and delete the software distribution folder in order to be remade new so we can eliminate corruption in the folder itself. To do this follow the guide: Press ⊞ WINDOWS + S to open the search menu Inside search type in Windows terminal, right-click on the terminal and click on Run as administrator. Confirm with YES on UAC prompt pop up Inside terminal press CTRL + SHIFT + 2 to open command prompt inside command prompt type in: net stop wuauserv and press ENTER Then type in: net stop bits followed with ENTER Next press ⊞ WINDOWS + R to open the run dialog Inside run dialog type in C:\Windows\SoftwareDistribution and press the OK button or ENTER File Explorer will open and you will find yourself inside SoftwareDistribution folder. Press CTRL + A to select all files inside Press on the delete icon or press DEL, confirm with YES Once all files are deleted, the system will redownload new ones.

Enable Cryptographic service

Windows 11 has come with a cryptographic service that aims to make your computer more secure but if the service is turned off it can be the cause of 0x8000ffff error. In order to turn this service back ON, follow the guide: Press ⊞ WINDOWS + R to open the run dialog In run dialog type in services.msc and press ENTER or click on the OK button In the list find Cryptographic Services and double click on it Inside properties click on Startup type dropdown menu and select Automatic from the list Click on the Start button to run service and then on the OK button to save the changes

Run SFC scan

SFC is an internal Windows tool for fixing corrupt system files, application will scan all system files and repair ones that are corrupted. To run an SFC scan do the following: Press ⊞ WINDOWS + S to open the search menu Inside search type in Windows terminal, right-click on the terminal and click on Run as administrator. Confirm with YES on UAC prompt pop up Inside terminal press CTRL + SHIFT + 2 to open command prompt inside command prompt type in: SFC /scannow and press ENTER Wait for the whole process to finish and reboot your system

Run DISM scan

Similar to SFC, DISM scan will scan your system Windows image and if required it will repair it. Press ⊞ WINDOWS + S to open the search menu Inside search type in Windows terminal, right-click on the terminal and click on Run as administrator. Confirm with YES on UAC prompt pop up Inside terminal press CTRL + SHIFT + 2 to open command prompt inside command prompt type in: DISM /Online /Cleanup-Image /RestoreHealth and press ENTER Wait for the whole process to finish and restart your computer

As more and more people get into insider preview of upcoming Windows 11 we will see more and more different takes and opinions on it. Generally speaking, the first wave was quite positive when it was previewed but how time is passing more and more limitations and frustration comes to the surface. Some of the limitation that is inside it, which have been confirmed by Microsoft itself includes features missing that we had in Windows 10 like moving the application to the taskbar in order to pin it, moving the file in the taskbar to open it in default application and some big annoyances like Windows opening widgets always in Edge no matter what is your default browser. Not being able to move the taskbar from the bottom is also one of many illogical things. There is not really a point in these missing features since they were working fine in Windows 10 and many users liked them since they could customize Windows more to their liking, now with this new look at limitations it reminds me personally much of apple macOS and I will be honest, I am not a big fan of that kind of thinking. If I wanted that kind of OS I would have gotten myself a MAC, not custom build PC, but hey, Linux is always a free alternative, and how Microsoft itself is pushing limitations and in my opinion bad design choices along with awful system requirements that might just be a case for a lot of users. I am really not sure what is logic behind these moves and I am sure they have their reasons but this time it seems that their take on the new OS is not resonating well with the overall user population, well at least what I have heard so far. Things of course can still be changed and made for the better and I would rather see release postponed and issues addressed than getting more system hogging and limited new OS that at its current state looks like reskinned Windows 10 with limitations.

What is Active History? A new feature has been introduced in Windows 10 that allows users to stay connected to their tasks across their devices. This new feature is called “Windows Timeline” and using this feature, users could continue their tasks all over their Windows 10 computers as well as on devices that run Android and iOS as well. This new feature was included in Microsoft Launcher and Microsoft Edge on Android devices as well as in Microsoft Edge for iOS devices. In order for the feature to work, you have to send either Basic or Full data and diagnostics of your computer to Microsoft which would sync it all over your devices with the help of the cloud. And now since all your data is stored on your Windows 10 computer and with Microsoft under your account, it is easier for you to access the back and start where you left off. This kind of option is called Active History. In this post, you will be guided on how you can permanently disable Active History using either the Windows Registry or Group Policy. Before you go on further, it is recommended that you create a System Restore Point first in case anything goes wrong. This is a precautionary measure you must take so that you can easily undo the changes you’ve made. After creating a System Restore Point, proceed to the given instructions below.

Option 1 – Disable Active History via Registry Editor

• Tap the Win + R keys to open the Run dialog box and type in “Regedit” in the field and hit Enter to open the Registry Editor.
• Next, navigate to this registry key: ComputerHKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsSystem
• From there, check if you can find a DWORD named “PublishUserActivities”. If you can’t find this DWORD, just create one with the same name and make sure that the base is selected to Hexadecimal.
• After that, double-click on the DWORD and change its value from 1 to 0 to disable Active History.
• Restart your computer to apply the changes you’ve made successfully.

Option 2 – Disable Active History via Group Policy Editor

Note that this second option won’t work if you are using the Home edition of Windows 10. This is because the Group Policy Editor does not come with Windows 10 Home. So if you are not using Windows 10 Home, follow the given steps below.

• Tap the Win + R keys to open the Run box.
• Then type in “gpedit.msc” in the field and hit Enter to open the Group Policy Editor.
• Next, navigate to this path: Computer ConfigurationAdministrative TemplatesSystemOS Policies
• After that, double click on the configuration listing named “Allow publishing of User Activities” to open the configuration page which has the following description:

“This policy setting determines whether User Activities can be published. If you enable this policy setting, activities of type User Activity are allowed to be published. If you disable this policy setting, activities of type User Activity are not allowed to be published. Policy change takes effect immediately.”

• Now you have to select Disabled or Not Configured if you want to disable Publishing of User Activities or Enabled to Enable Publishing of User Activities depending on your preferences.
• Next, click OK and exit the Group Policy Editor and then restart your computer to successfully apply the changes made.
