How to Fix Missing MSVCR80.dll Error

Recently, some users reported not being able to boot up their Windows 10 computers. And during the startup phase, at some time, the bootup sequence is halted with a Recovery error along with an error message saying, “Your PC/Device needs to be repaired” with an error code of 0x0000605. This kind of error message indicates that Windows was not able to verify the digital signature for the file as the signing certificate or it could be that it has expired. To resolve this error, you can follow the potential fixes given below and see if you stumble upon a fix that might work out for you.

Option 1 – Change the Date & Time settings in the BIOS

Some users reported that they were able to fix the error by changing the Date & Time settings in the BIOS. Upon checking, they saw that in their BIOS settings, the date was off several years. As a result, the incorrect date and time settings end up ticking the system into believing that the Windows build has expired long before the actual expiration date. You can check if the error pops up due to the same reasons by accessing the BIOS settings. To do so, you have to tap the Boot key that’s associated with your motherboard manufacturer during the initial startup phase. After that, you can search for a particular boot key online or you can also tap keys like F2, F4, F8, F10, F12, and the Delete key. Once you’re able to access the BIOS settings, locate the Date & time or anything similar, and then check if the date is correct or not. If not, you need to change the date to the actual date and then save the changes made and restart your computer and then check if the issue is now fixed or not. Just remember that if the actual date is past the expiration date of the build you have, you need to change it to an older date. If your Windows 10 PC is able to boot back up, you have to update it to a stable Windows build and then go back to the BIOS settings and change the date to the current one else you will definitely encounter Windows update errors in the future as well as security alerts.

Option 2 – Perform a clean install of a stable Windows 10 build

If every system boot fails accompanied by a BSOD error with error code 0x0000605 “A component of the operating system has expired” and you’ve already followed every instruction on option 1, then it’s most likely that your current Windows build has already expired. Remember that almost all the Windows 10 Insider Preview builds (98xx) are created along with an expiration date and when your computer reaches the expiration date, you won’t be able to boot your computer up. Note that the exact expiration date varies based on the build number. And prior to the expiration date, the operating system will start to display some error warnings telling you that the build will expire and urge you to update the most recent build available. And so once the computer reaches its expiration date, it will begin to reboot every three hours until it no longer boots up which is about 2 weeks approximately after the license has expired. Once the expiration date is up and your computer no longer boots up, you need to perform a clean install and then install the latest Windows 10 build to resolve the issue once and for all.

If you have multiple keyboards, things can get quite tricky. There are times when the keyboard language changes on its own since the keyboard changes while you are typing. The thing is, the keyboard changes because sometimes we accidentally tap shortcuts like Win key + Space key or Alt + Shift or Ctrl + Shift which changes the keyboard pairs or language. Thus, if your keyboard language changes on its own, there are two ways to resolve it. First, you have to make sure that Windows 10 does not add keyboards without your permission. Second, you have to make sure that the shortcut keys don’t change the keyboard language. This second option is what we’re going to discuss in this post. You need to first set a different input method for each app window. To do that, you have to disable the change in layout. Refer to these steps:

• Go to Settings > Language and input.
• Next, type “switching input methods” to open the Advanced keyboard settings with this option inside.
• After that, select the checkbox labeled as “Let me set a different input method for each app window” and then click the Save button.
• Restart your computer.

Now that you’ve disabled the change in layout, you now have to find the keyboard settings. Just go to Settings > Devices > Typing > Advanced Keyboard settings. From there, you have the option to select which keyboard is going to be used for any app. When you change the keyboard every time you use an app, usually, Windows remember it so that you won’t have to set it up all over again. In addition, the Advanced keyboard settings page also allows you to override the default input method which could be different from the first one in your language list. Aside from that, there is also a Language bar option that comes in handy as you can quickly switch between keyboards. And if you removed it, you have the option to restore the language bar back as well. Now all that’s left for you to do is to change the Language Settings under the Administrative tab. A user from a forum that came up with this solution, reported that the issue occurred when he started typing in some program with non-Unicode characters which caused Windows to use the default system local language to interpret these characters even though the language is unavailable in the Language bar. To change the Language Settings under the Administrative tab, follow these steps:

• Go to Settings > Time and Language > Language > Administrative language settings.
• After that, click on Copy Settings under the Administrative tab.
• Now make sure that all the Display language, Input language, and Format are English (United States) or any language you prefer.
• Then mark the two checkboxes in “Copy your current settings to Welcome screen and system accounts & New user accounts”.
• After that, click OK and then exit.

Note: You also have the option to disable those shortcut combinations which can change your keyboard settings accidentally.

The screen flickers into black, it comes back and on-screen there is a message Driver stopped responding and has recovered. If you have been through this you are aware that the issue is not serious but it can get pretty annoying fast since you are not aware when will it happen again, and it will happen again. In this guide, we will go through the usual reasons for this error and offer solutions to them. Follow the guide step by step in order to resolve the problem.

1. Clean your PC Dirt and dust are your enemy no1, dirty graphic card can not be properly called and can cause overheating which can result in this particular error, make sure that your PC is clean and tidy in order to eliminate dust and dirt as a cause for malfunction.
2. Turn off multiple applications and try running just one at a time Overburdening GPU can cause this error to appear since the graphic card can not handle all requests it gets from multiple active applications. Try to run just one application at a time for some time period to see if the error will appear again.
3. Update driver Update your GPU driver to the latest version from the manufacturer's website, Display Driver Stopped Responding and Has Recovered Error in Windows 10 can be from outdated drivers not able to handle modern tasks
4. Get newer GPU As hard as this advice is, sometimes the reason is an old graphic card that simply can not keep up with modern games and applications, upgrade it to a more modern GPU and watch errors go away.

This procedure is slightly long and tricky. To try it, you need to be technically sound. Here’s what you have to do: first create a parallel installation of Windows NT. Start your PC to the parallel installation and then open the Registry Editor. On the Registry Editor’s Windows menu click HKEY_LOCAL_MACHINE on Local Machine and then click Load Hive. Now type the path %systemroot%system32configsystem into the System hive of the prior installation. Then click open. Here you will be prompted to enter the name of the key, type TEST. Note the setting for the current DWord value in the preceding registry key. This is 0x1 and is denoted by CURRENT:Reg_Dword: 0x1. This value indicated that the Current Control Set for your original Windows NT installation corresponds to ControlSet001 in this window. Now if the value is 2, it indicated that the Current Control Set corresponds to ControlSet002. Now locate the following registry key: HKEY_LOCAL_MACHINETESTControlSetXXXControlSession Manager. XXX is the Current Control Set Value. And delete any pending file rename operation entries. Then click TEST hive and then click Unload Hive. After that again repeat the process, open the registry menu and click load hive, here type the path %systemroot%system32configSoftware to the Software hive of the prior installation and then click open. Now you type TEST 2 when you are prompted for the name of the key. Remove any pending file rename operations entries in the following registry keys: HKEY_LOCAL_MACHINETEST2MicrosoftWindowsCurrentVersionRunOnce HKEY_LOCAL_MACHINETEST2MicrosoftWindowsCurrentVersionRunOnceEx Now click TEST2 hive and then click unload hive. Quit the Registry Editor and then restart your original installation. This will resolve the stop C000021A error.
