"Second, I disabled a huge amount of useless services and it made possible to free RAM considerably [~34MB] and reduce amount of running processes too."Later I decided to repeat my tests on disabled services in more exact way. Finaly, there are the results.
Testing system was identical in both cases, except the recent was with advanced WiFi driver [Intel v.10.5.2] that extra 50MB & 80 files added in comparison to previous used “cut” by Sony v.10.1.0.11 [without Intel control console, but this console works better than MS one]. There is needed to note that at the step of WiFi driver installation it is necessary to install driver v.10.1 first and then upgrade with driver v.10.5. If installation of driver v.10.1 is omited, then Wireless Device Switcher would not work at all. Apparently native driver v.10.1 has something added from Sony in order to fit in with utils. [I think this note is in regard to some Sony notebooks only.]
So was PC: notebook Sony VGN-Fe11s, T2400, 1GB RAM, NVIDIA GF7400, XP Pro SP2 MCE OEM-preactivated original_CD.
Status: freshly installed OS plus necessary drivers [13] and utilities [10], defragmented.
A. Services are intact Physical memory:
- Total: 1046,6 MB
- Available: 780,6 MB
- System cache: 117,3 MB
- Used RAM [Total minus Available]: 266 MB – apparently some portion is not documented and some reserved for Video.

Processes: 37
Threads: 394
Boot up: 45,1 s
Shutdown: 14,3 s
Services started: 49 [Auto: 40, Manual: 9]
B. After useless services have been disabledPhysical memory:
- Total: 1046,6 MB
- Available: 802,2 MB
- System cache: 112,6 MB
- Used RAM: 244,4 MB

Some notes= All measurements are done after 5 minutes boot process has been finished in order to minimize impact of transient, short-time processes.
= Values are based on Windows Task manager data and are typical [~ ±0,5 MB] for number of boots.
= System_cache showed itself of being the most unstable parameter. For example, in some cases at the stage
A it showed ~127,7 MB, while most common value is ~117,3 MB; in some cases at the stage
B it showed ~116,8 MB, while most common value is ~112,6 MB. I can’t explain this phenomenon, maybe MS profies could. It is seemingly most obscured parameter in Windows Task manager [but not the only unclear point]. Common sense hints me that system stability means its parameters’ repeatability, especially, when system is freshy installed.
= It was disabled only these services that has no impact on my daily PC use as Home user, e.g. keep on operating WLAN, LAN, using Bluetooth, built-in camera etc. When using LAN, there may would be needed in some environment not to disable Windows Time service [I have disabled it]. Another good step in resource cleaning is to delete or move to safe place Bluetooth Manager shotcut from Startup folder [any program placed there starts on PC boot] – doing that the amount of processes in Task manager is reduced by 4 and Bluetooth still will work when turned on. Therefore, I did not test Bluetooth functionality in more detailed way. There are needed some external devices to plug in, recently I don’t have them available.
ConclusionsMost representative parameters are… I can say, all of them, except System_cache that is with some dose of unpredistability and obscurity. By the way, it’s very interesting – 27% of threads are down !
I suppose, these results could be a good comparison base for notebooks with factory-installed OS [and, of course, with a variety of added staff], or even desktops that usualy have fewer OEM drivers and utilities installed. Personally I can not make such kind of comparison because I do not have any saved image of factory-made recovery OS for my notebook. Results from other users are welcome.
Added:
There are screenshots of W. services after unused ones have been disabled.
