Information that is added on the Internet hardly ever go away which is highly problematic if the information is not correct. It becomes even more disturbing in sectors where everyone can have his say and it is not really a secret that most PC users have their list of recommended tweaks for Windows.
It's fairly interesting that some of the tweaks that do not work have made it into tweaking applications and that new Windows tweaker sometimes contain these as well. Not working means that they either have no positive effect on the system or are even hurting performance or the system in general.
The following list contains 5 Windows tweaks that are fairly popular on the Internet but it has been proven that they have no positive effect on the computer.
1. Deleting the contents of the Prefetch Folder: - Deleting the contents of the Windows prefetch folder will actually degrade system performance during startup of the applications that are listed in the folder. The folder contains a maximum of 128 pf files that Windows uses to quickly look up load information for the corresponding file. The folder gets cleaned automatically once the 128 file limit is reached.
2. Unload DLLs: - AlwaysUnloadDLL is a Registry setting in Windows that is very popular in tweaking utilities. Enabling this setting supposedly frees up system memory. The key has in reality no effect on Windows NT systems and was only used in pre-NT systems.
3. Enabling Superfetcher in Windows XP: Superfetcher is a feature of Windows Vista that does not exist in Windows XP.
4. Disabling System Restore: - Creating a System Restore Point is a quick process that normally only lasts a few seconds while the monitoring of the system causes no apparent performance loss. The only reason to disable System Restore would be lack of hard disk space.
5. Disabling QoS will free up the 20% bandwidth: - I'm seeing this tip all over the Internet. "Networking Quality of Service (QoS) refers to a variety of techniques that prioritize one type of traffic or program that operates across a network connection instead of relying only on "best effort" connectivity." The computer is using 100% of the bandwidth but 20% can be reserved by programs when sending data. In reality disabling QoS has normally no effect on the bandwidth of the computer.
