Menaikkan Speed Internet

Windows (Win XP Pro dan2000) sebenarnya tanpa kita ketahui juga telah mencuri bandwidth kita sebesar 20%. Bandwidth sebesar 20% ini digunakan oleh Windows untuk mendownload update-update terbaru (auto update) untuk Windows itu sendiri. Bayangkan, bila kita bisa mengalihkan bandwidth ini untuk keperluan browsing kita, maka secara otomatis kecepatan internet kita akan meningkat sebesar 20%. Untuk Menbuatnya langkah-langkah adalah sebagai berikut:

1.      Klik Start => Run lalu ketik gpedit.msc.

2.      Maka akan tampak tampilan “Windows Policy”

3.      Kemudian masuk ke : Local Computer Policy => Computer Configuration => Administrative Templates => Network => QOS Packet Scheduler

4.      Kemudian pada kolom sebelah kanan pilih Limit Reservable Bandwidth, disitu tertulis Not Configured => Double click.

5.      Jika ingin tahu keterangannya buka tab Explain, di situ tertulis keterangan bahwa Windows secara default menggunakan 20% bandwidth kita.

6.      Kembali ke tab Setting dan pilih Enable, Kemudian rubah value 20% menjadi 0%.

Fix Dvd/Cd Room Disappeared

before doing the hack make sure You really need it. Go to View system information then go to Hardware Tab and choose device manager. Go to Your CDROM/DVDROM/RW drive and try to ‘fix the issue’. It prolly wont as WinXP wont see CDROM/DVDROM/RW drives.

Okay so heres the fix without useless talk:
1 – Start Menu > Run > type regedit aka enter Windows Registry [dont worry it iwll be easy]
2 – Go to HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Class entry

so it would be path: H_L_MSystemCurrentControlSetControlClass{3d36e965-e325-11ce-bfc1-08002be10318}
4 – Click UpperFilters and LowerFilters keys from WIndows Registry to highlight them, then simply delete both of them without blink of an eye.
