The location for system registry files in Windows NT is %SystemRoot%\System32\Config; the user-specific HKEY_CURRENT_USER user registry hive is stored in Ntuser.dat inside the user profile. There is one of these per user; if a user has a roaming profile, then this file will be copied to and from a server at logout and login respectively. A second user-specific registry file named UsrClass.dat contains COM registry entries and does not roam by default. The Windows Registry is a database of settings used by Microsoft Windows system applications and core utilities. The registry of often abused by adversaries to either store configuration information, hide code, evade detection, inhibit system function, establish persistence among other reasons.
Unless you’re using an older PC, you’ll likely see UEFI instead of BIOS menus when adjusting overclocking settings and making other low-level tweaks. But for simplicity’s sake, we’ll continue to use “BIOS” to refer to UEFI. If your operating system loads before you have time to enter the hotkey, try the Windows 10 and 11 method above to restart directly into the BIOS. Accessing the BIOS from Windows 10 or 11 can be an easy solution if your PC boots up too quickly to use keyboard commands on startup. When you run into hardware problems, it’s common to ask whether you can solve them by updating your BIOS. Save older backups after you upgrade – Once you switch over to Windows 10, make sure you keep older backups of your data. You may need them again if you update to a newer Windows version.
DLLs are binary files, so you have to use a hex editor to edit them. If you don’t have the source code to them, you’ll have to use a disassembler to get readable code. If nothing else works, you will be required to download the file on your own. You can find many sites online that will have a complete list of DLL files available for download. You can download the file from online source and should be able to run your application smoothly. This is one of the most annoying situations that most of us face at some point in time while running applications on our system.

Find out how to choose a motherboard that best fits your build. Once you have the product model, navigate to the manufacturer’s product support page and look for the product manual. A BIOS or UEFI chapter should explain several ways to “flash” — or update — the BIOS. There may also be a guide on the BIOS tab of the product page. An update addresses newly-discovered security flaws.
- Many enterprise applications store their configuration information in the Windows registry, in local .XML files, or internal application-specific configuration stores.
- During P-state, the CPU stays active & scales its voltage to increase frequency.
- Before you go any further, you should check your update history and see if an update has failed.
- REG_DWORD – This type represents the data by a four byte number and is commonly used for boolean values, such as “0” is disabled and “1” is enabled.
- For version 1909 or earlier, click Advanced options and set your deferral periods for monthly quality updates.

If this doesn’t fix the issue or face performance issues as soon as you disconnect the power source, even if the battery is fully charged, I recommend you go through the solutions mentioned below. Microsoft will support other processors in the next few months. However, if you want the best performance whether you are plugged in or not, then you might want to disable Power Throttling. Even if you decide to disable the feature, I recommend you use the first method, as it gives you better control without messing up the policies or registry keys.
Other hives like HKEY_DYN_DATA are only virtual objects in Win32 API and thus not linkable. Links are used in Windows for only CurrentControlSet and Hardware Profiles\Current. Abbreviated HKCR, HKEY_CLASSES_ROOT stores information about registered applications, such as file associations and OLE Object Class IDs, tying them to the applications used to handle these items. On Windows 2000 and above, HKCR is a compilation of user-based HKCU\Software\Classes and machine-based HKLM\Software\Classes. If a given value exists in both of the subkeys above, the one in HKCU\Software\Classes takes precedence. The design allows for either machine- or user-specific registration of COM objects. The user-specific classes hive, unlike the HKCU hive, does not form part of a roaming user profile.
