Diablo 2 resurrected has hit official release and servers seem to be finally taken care of and everything seems to be running smoothly now. The game also received great praise from gamers and attracted old players of the original Diablo 2 game. Speaking of old players of old Diablo 2, they can transfer their old characters into remaster and continue playing them within this new great HD environment. There are some steps and requirements but we are here to help and transferred characters will bring full stash, inventory, and equipped items with them.

Requirements

There are not many requirements for this transfer to occur but they must be respected in order to be successful. The first thing is a minor requirement and somewhat annoying but it needs to be done, firstly fire up Diablo 2 resurrected and create a character, any kind of character with any kind of name, any kind of class. This strange requirement is to actually create a character folder and register it inside D2 resurrected so we can copy old ones there. The second requirement will be that characters that you wish to be transferred must be offline characters. Old battle net online characters cannot be transferred at this moment and probably will not be in the future as well. So for all of you that wish to transfer online characters, bad luck, for the rest of us casuals playing offline single-player mode, we can enjoy our characters.

Process of diablo 2 character trasfer

The process itself of transferring characters when previously mentioned requirements are met is just a simple and copy operation. If you have somewhere backed your characters go into your backup folder and copy files in c:\users\*current user*\saved games\*diablo 2 resurrected folder* If you do not have characters backed up and just have old Diablo 2 installed and playing it, you can go to c:\users\*current user*\saved games\*diablo 2 folder* and just copy all characters files into c:\users\*current user*\saved games\*diablo 2 resurrected folder* Your old characters end with .d2s extension, grab all that you want to transfer, and copy them into D2R. Take note that copied characters cannot be brought back into Diablo 2, once they are copied into Diablo 2 resurrected all further progress on them will be tied to the new game.

Conclusion

That’s it about the transfer process and requirements for it. Fire up the new game version and enjoy.

A surprisingly large amount of things present at your home can and do interfere with your wi-fi signal making it weak so devices are dropping it, having trouble connecting, or being slow.

Hello and welcome to our latest article where we will take a look at all things that are present in a lot of homes but are very bad for your WI-Fi signal.

Bad router placement

Having a router in a bad position can have some really large effects on WI-Fi signal strength and its availability. Usually, we do not give great attention to where we are placing our router but it has been proved over and over again that being close to certain objects does indeed have a great influence on the wireless signal strength and performance.

So, what are these objects and bad positions where we could place the router and effectively kill his Wi-Fi capabilities?

Fish Tanks

Water will block all radio waves including Wi-FI signals and waves themselves, so having a router next to the aquarium or any large source of water is a bad idea. You should always look at water as something bad for your Wi-Fi and move your router away from it as far as possible.

Bookshelves

Paper is another story and example of the dampening effect on radio waves. Did you know that various patterns of paper are used in silent rooms and recording studios in order to eliminate sound reflection from surfaces? Well besides absorbing sound waves, the paper also absorbs Wi-Fi signals and if you have a large bookshelf with a lot of books packed one beside another you just have a great wall of signal absorbing.

Mirrors

The problem with mirrors is in their coating that goes over the glass in order to turn it into the mirror, that coating is metal and as such, it is absorbing signals in large amounts. If you have an old or high-quality mirror that has a silver coating things are even worse since silver will absorb even more waves than modern cheap ones.

TV

Yup, TV is also on this list and for a similar reason as a mirror, although TV does not have coatings of metal, they have something even worse: a large metal plating on the back. Metal plating is there to produce structural integrity of the TV set and provide it with shielding from electromagnetic waves and as such it will prevent Wi-Fi waves as well. Do not place the router behind your TV.

Things that influence signals in homes

Any kind of metal decoration

Now when we covered mirrors and TV because of the metal they have, we must take a look at the metal itself. Any kind of metal stuff that you might have like baskets, figures, statues, frames, etc will effectively block your signal.

Kitchen appliances and Home utilities

Kitchen appliances like refrigerators, microwaves, ovens, stoves, etc. along with home appliances and utilities like dishwashers, washing machines, dryers, etc are large metal objects enclosed in a metal cage that will block signals from spreading further and it is no secret that most kitchens have weaker Wi-Fi because of this reason.

Home gyms

This is a logical conclusion as to everything explained so far if you have a workout room or small gym at home it is probably filled with weights that are metal and have mirrors inside, all of that will interfere and block signals.

Things blocking your Wi-Fi that you have no easy control over

Walls

Thick walls will dampen signals, thick walls from bricks will dampen even more and concrete walls will kill it almost completely. Any kind of metal reinforcement wiring inside walls will reduce and kill signals as well.

Floors and ceiling

This is somewhat important if you have a floor beneath or under the room where is your router located, but for the same reason how walls are blocking your signal floor and ceiling can do it as well, especially since most of the time they are made of some stronger material like concrete with metal fence inside.

Heating systems

If you have a heating system that is composed of metal radiators with water inside, then in terms of Wi-Fi signal strength you have an aquarium but in a metal box, and as such it will greatly reduce signal strength.

The issue with the abrupt system reboots to force Windows 10 updates on a computer has been lessened with Active Hours. This feature keeps a record of the hours during which a system remains active and prevents the installation of updates during such hours. For example, when a system restart is needed to complete the installation of an update, Active Hours delays the update and allows you to finish what you’re doing on your computer. Thus, if you haven’t heard of this feature, then now is the time you do, read this post to configure and use Active Hours in your Windows 10 computer. There are three ways you can configure Active Hours. The first one is for general users, whereas the rest of the two methods are for users who knows their way about the Windows Registry and Group Policy. To get started, refer to every given option below.

Option 1 – Configure Active Hours via Windows 10 Settings

• Go to Settings > Update & Security. From there, click on the “Change active hours” option under the Windows Update section.
• Next, you can select a time (“Start time” and “End time”) during which the restart can occur.
• After that, click on the Save button and exit.

Note: Keep in mind that the values you’ve entered indicate the hours during which your system is in use, namely, ACTIVE. It is important for your active hour’s interval period and it can be anything between 1 and 18 hours since you can’t go beyond 18 hours. In addition, there is no option to configure different active hours on different days and you can’t specify different active hours for weekends and weekdays as well. On the other hand, Windows 10 also offer users an option to override Active Hours. All you have to do is go to Settings > Update & Security > Windows Update > Restart Options. From there, you can choose a custom restart time when your computer will restart to install the updates but this is only a one-time setting.

Option 2 – Configure Active Hours via Registry Editor

• Tap the Win + R keys to open the Run utility and type “Regedit” in the field and tap Enter or click OK to open the Registry Editor.
• Next, navigate to this registry path: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsUpdateUXSettings
• In the given registry path, you can choose to change “ActiveHoursStart” and “ActiveHoursEnd”.

Note: There are no extra settings available in the Registry Editor but you can change the remote computer’s Active hours settings using the Registry Editor.

Option 3 – Configure Active Hours via Group Policy

Note that this option is available for the Windows 10 Pro and Educational or Enterprise versions. It is mostly used by computers in Business or through remote access. To get started, follow these steps:

• Tap the Win + R keys to launch Run and type “gpedit.msc” in the field and tap Enter or click OK to open the Group Policy Editor.
• Next, navigate to this group policy setting: Local Computer Policy > Computer Configuration > Administrative Templates > Windows Components > Windows Updates.
• From there, look for a policy labeled “Turn off auto-restart for updates during active hours” and double click on it. This will open a new window.
• Click on the Enabled radio button to enable Active Hours. You also have the option to choose active hours just like in the first given option above. It works just fine except when the following policies don’t override:
  • No Auto-restart with logged-on users for scheduled automatic updates installations.
  • Always automatically restart at the scheduled time.

• Since Group Policy allows you to reduce the range of active hours, you can configure it if you want it to be less than 18 hours. Just find the policy setting labeled “Specify Active hours range for auto -restarts. The minimum is 8 hours”.
• After you set the Active Hours, click the Apply and OK buttons to save the changes made.

There are times when the Windows Search doesn’t work and you wouldn’t have a clue as to why it happened since it does not give any error codes. In such cases, you have to check the error logs in the Event Viewer to find out more about the problem. From there, look for an error with the Event ID 3104 in the Windows error logs and if you see an error message that says, “Enumerating user sessions to generate filter pools failed”, read on as this post will guide you in fixing the problem. Apart from the error message, you might also see more information in the details section of the log that says, “(HRESULT: 0x80040210) (0x80040210)”. This kind of error is most likely caused by something that prohibits the search function from initializing. A lot of users assumed that it could be due to Cortana but it’s actually not. While some users also reported that they encounter the issue after they restarted their computers. This error was also reported with the same event ID 3104 on the Windows Server. According to security researchers, this error could be caused by problems in the Registry entry of Windows search. It could also be due to an issue with the SYSTEM account where it hasn’t been added to the DCOM Security. It is also possible that the Windows Search function has not been initialized. To fix this error, you can try to rebuild the Search Index manually or run the Search and Indexing troubleshooter. You can also check the startup type of the Windows Search service or try some registry tweak.

Option 1 – Try to rebuild the Search Index manually

The first thing you can do to fix the problem is to manually rebuild the Search Index. You can do that by going to Control Panel > Indexing Options and from there, click on Advanced. After that, go to the Index Settings tab and then click on Rebuild > OK. Once you’re done, check if it fixed the problem.

Option 2 – Try running the Search and Indexing troubleshooter

You could also run the Search and Indexing troubleshooter in Windows 10 as it checks whether the settings are in place and automatically corrects any issues with the Windows 10 search function. To run this troubleshooter, just click on the Start button and select Settings > Updates and Security > Troubleshoot. From there, select the Search and Indexing Troubleshooter. Once the troubleshooter is done, restart your computer and see if it fixed the error.

Option 3 – Try checking the startup type of the Windows Search Service

In this option, you have to check the startup type of the Windows Search service since the service won’t start. To do so, refer to these steps:

• Tap the Win + R keys to open the Run utility and type “services.msc” in the field and then tap Enter to open the Services Manager.
• Next, from the list of services, look for the Windows Search Service or WSearch. Once you find it, right-click on it and select Properties.
• After that, change the Startup type to Automatic and click on the Start button if the service is in the Stop state.
• Now click on the Apply and OK buttons to save the changes made and then restart your computer.

Option 4 – Try changing the Registry entry for Windows Search

Before you apply some registry tweak, you need to create a System Restore point first. Once you have that covered, follow these steps:

• Tap the Win + R keys to open the Run utility and type “Regedit” in the field and tap Enter to open the Registry Editor.
• If a User Account Control prompt appears, just click Yes to proceed.
• After opening the Registry Editor, navigate to this registry path: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows Search
• From there, click on Windows Search and look for the key named “SetupCompletedSuccessfully” and change its value to “0”. Just right-click on it and select Modify.
• Then input “0” as its value data and click on OK to save the changes made.
• Exit the Registry Editor and restart your computer.
• Now check if the Enumerating user sessions to generate filter pools failed is fixed or not.
