Returns the value data of up to three Windows Registry properties. Get Mark Richards’s Software Architecture Patterns ebook to better understand how to design components—and how they should interact.
- If a server’s virtual memory is misconfigured, page file thrashing will consume a majority of the CPU cycles.
- In the new window that opens, click on the System Restore button.
- You can back up and restore the Registry in several ways.
- Different methods to bypass UAC exist, but this blog post is focused on registry modification techniques.
These options can be set completely within the registry. It’s a useful functionality for Windows programming, but can be exploited as a method to maintain persistence. The attacker made everything from inside the SQL Server service without actually having access to the OS, but still had a deep impact on the underlying OS configuration. This detection won’t work for a registry key where there are no nested subkeys i.e. for the RUN/RUNONCE keys.
To remove a key , the key name must be preceded by a minus sign (“-“). E.g. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows refers to the subkey “Windows” of the subkey “Microsoft” of the subkey “Software” of the HKEY_LOCAL_MACHINE root key. Windows 2000 keeps a backup copy of the HKEY_LOCAL_MACHINE System key that it uses to troubleshoot a problem with the existing one. The “Office Test” persistence mechanism allows threat actors to execute a Trojan each time a user runs any of the Office applications.

To address this problem, you’ll need to open up the Registry Editor and modify the value data of the DisableAntiSpyware key. In this case, you can either use a 3rd party repair utility to get the issue fixed or you can go for a repair install. You need to select the product executable directly and Ctrl+click it to use the Show Package Contents command to access the product directories listed below. Animations and various cool transitions look good but they also take a toll on your PC’s CPU and memory. Thankfully, Windows lets you optimize the effects for the best performance. To optimize Windows 10’s performance, go to Control Panel and in the search box, type “performance”. From the search results, click on“Adjust the appearance and performance of Windows”.

Rebooting clears various caches stops running processes, and allows certain background updates/patches to fully install. However, sstpsvc.dll if your PC is always running at a high CPU load, this may not solve the problem. Most computer users have encountered a “slow down” problem at one point or another. Sometimes it happens when resource-intensive software, such as games, are running. Still, it can also happen somewhat inexplicably — much to the user’s frustration. In many cases, the problem can be traced back to a CPU that is running too many tasks and processes.
S0375 Remexi Remexi utilizes Run Registry keys in the HKLM hive as a persistence mechanism. S0332 Remcos Remcos can add itself to the Registry key HKCU\Software\Microsoft\Windows\CurrentVersion\Run for persistence.
